  • Because stainless steel metal sheet processing parts are easily deformed, a centrifugal finishing machine with a small-capacity working barrel is used to reduce the operating speed and use it with softer texture cone-shaped resin media (also called plastic media) is used to chamfer and deburr. If you use ceramic tumbling media or other very hard abrasive media will cause problems such as deformation and bending of the workpiece, and ceramic deburring media can easily contaminate the stainless steel surface and make the surface black.
  • So why don’t polish parts use vibratory polishers? Because the vibrating polishing machine will cause the thin parts to stick to each other, and multiple pieces will fit together, which will not achieve the finishing and polishing effect.
  • Products can be separated automatically using a vibrating separator, to control the vibration amplitude of the vibrating separator so that no bending deformation occurs due to mutual collision.
  • In order to improve the anti-rust and anti-corrosion performance of the product after water cleaning, vibrating dryer, with corn cob polishing media, dry the moisture and wipe away water stains on the surface of the product.

5. Additional instructions
  • Because stainless steel is harder material, ceramic deburring ball is used for rough finishing to remove scale and burrs. If you use angle cut triangle ceramic deburring media or angle cut cylinder ceramic deburring media with sharp corners or edges will cause scratches, pitting and other problems on the surface of the product.
  • The workpiece material is hard and has no edges and corners, so it can be automatically separated by a machine. There will be no surface damage caused by collision with each other, which greatly improves the efficiency of discharging materials.
  • For stainless steel product parts, polish with stainless steel polishing ball is very effective in brightening. The surface of the product after rough finishing has no luster, but it will become bright after vibratory fine finishing and polishing with stainless steel media.
    In order to further improve the smoothness and brightness of the product surface, finally use tumbling barrel polishing machine, combined with walnut shell polishing media, achieves a quasi-mirror polishing effect with the support of polishing paste.

  • Because the workpiece material is relatively soft, resin media can only be used to roughly remove scale and burrs. If you use ceramic deburring media, so the hardness is too high and the sand grits are too coarse, it will wear the surface of the product and cause scratches, pitting, color contamination and other problems.
  • Also because of the material, if a machine is used for automatic separating, the collision of workpieces will cause surface damage.
  • Zinc alloys can easily re-oxidize when exposed to water and air. Therefore, we need to dry the water immediately after polishing.

6. Final summary
  • In this case, we demonstrate a process of using a resin (plastic) finishing media to deburr, remove scale and brighten on the surface of a zinc alloy handle.
  • This process is also suitable for polishing belt buckles, jewelry pendants, souvenirs, craft gifts and other products produced from aluminum alloy and copper die-casting parts.

5. Additional information
  • Because the motorcycle starter lever accessories are made of pig iron forgings and the material is very hard, ceramic media with heavy cutting force is used to roughly remove scale and burrs. In order to fully finish the corners of the parts or the toothed inner wall of the inner ring, the shape of the ceramic media is a chamfered cylindrical tumbling deburring media, and the smooth curve of the cylinder itself can have a smooth surface on the starting rod. Smoother polishing effect. It should be noted that if the starting rod is made of aluminum forgings, then our tumbling finishing media cannot use ceramic media, but needs to use softer materialResin media (also called plastic media).
  • These motorcycle parts are not afraid of hitting each other, so in order to improve the screening efficiency, the finishing machine uses the vibrating bowl finisher with separator.
  • Iron workpieces are easily oxidized again when exposed to water and air. Therefore, we need to dry the water immediately after finishing and polishing.

6. Final summary
  • In this case, we demonstrate the process of deburring and descaling on the surface of a forged motorcycle workpiece, also called a starter lever, starter rod, and spark lever, and further improving the surface gloss and brightness.
  • This process is also suitable for polishing parts and components such as automobiles, bicycles, fishing gear, pumps and valves, sewing machines, equipment and tooling produced from forged iron.

The production and manufacturing process of vibratory finishing machines

Let’s take a look at how a Vibratory Finishing Machine changes from a steel plate into a polishing artifacts for deburring and descaling.

Vibratory finishing machine production process
  • 1. Blanking

    The purchased steel plates of standard sizes are cut into small iron plates according to the sizes of different machine models. The factors that affect the quality of machine products in this link are the quality and thickness of the steel plate. Our steel plates are all from the large factory of Shanghai Baosteel, with uniform thickness, and are all 4mm thick plates.
  • 2. Forming

    The cut steel plate is rolled into a cylinder with a plate rolling machine, which is used as the base of the machine and the barrel-shaped cylinder in the middle of the working chamber for installing the motor. Another main component is the bowl-shaped working chamber of the machine, which is pressed out using a hydraulic press and a special mold. In this way, the main components of the machine frame are finished.
  • 3. Welding

    This process is to weld the two ends of the rolled cylinder just now, and at the same time weld the bottom heel under the base to assemble the support of the vibration spring. This process can also affect the quality of the machine. Because the welds are not up to standard, problems such as cracking and falling off may occur during future use.
  • 4. Inspection and Finishing

    Check the surface condition of the weld, remove welding slag and oxide scale, use a grinder to grind the weld, and polish flash and burrs. Everyone knows that details are the devil, especially in the production process of industrial products, some seemingly inconspicuous small details often determine the final quality of the product. Blisters, small cracks in welds, flash and burrs on the surface of accessories will ultimately determine the appearance quality and service life of the machine.
  • 5. PU Casting

    Lining the inner wall of the hydraulically formed working tank with wear-resistant polyurethane colloid is the task of this process. During casting, a mold with a diameter smaller than the external frame body should be placed in the chamber, the external frame body and the mold should be fixed, and then the hot-melted PU glue should be poured into the gap between the frame and the mold. After the colloid cools and solidifies, it can be removed. After molding, the working chamber lined with PU glue is ready. This link is a key process that affects the service life of the machine. The wear resistance, thickness, and hardness of PU glue are factors that affect the length of use. Our polyester raw materials are all products from Dow Chemical (DOW) in the United States, and the casting thickness can reach about 15-20cm.
  • 6. Painting

    The next step is to spray paint on the surface of the working chamber and base, which can protect the iron plate and improve the aesthetics of the machine. Apply putty on the surface of the iron plate first to repair some obvious defects, such as pits, gaps, etc. After the putty dries, you can spray various beautiful colors.
  • 7. Assembling

    All required parts are ready. The next step is to put them together. First, a vibration motor needs to be installed in the middle cylindrical barrel of the machine. Install the motor to the base using a flange. The upper and lower ends of the motor are equipped with eccentric swing arm, commonly known as hammers. This is the main component for adjusting the direction and speed of the machine’s movement.
    Another major installation task is the installation of the base spring. Put the springs one by one on the support tubes on the base, so that the working chamber is suspended and supported on the base. The eccentric excitation force of the vibration motor will be brought to the chamber body to produce a spiral tumbling motion.
  • 8. Self Testing

    After all the installation steps are completed, it is the last step of power-on self-test. Connect the machine’s power cord to the control box and press the start button to start the machine. In this step, you need to check whether the direction of rotation and rolling of the machine is correct, whether the vibration frequency and amplitude are normal, whether there is any abnormal noise, and whether the installation and tightening bolts are loose. If everything is OK, it can be packaged and shipped.

What is stainless steel media?

About Stainless Steel Media

  • 1. What is stainless steel media?
  • As the name suggests, stainless steel media are tumbling media made of stainless steel. This is a kind of mass finishng, tumbling polishing, brightening and smoothing abrasive media mainly used in the finishing industry.
    Stainless steel media act on your product parts and workpieces and have the functions of deburring, cleaning, degreasing, brightening, and mirror polishing. Most metal parts can obtain a shiny surface effect after polishing.
    High-quality stainless steel raw materials produce high-quality stainless steel media. They have a long service life and can be used for a long time. They are the best choice for tumbling, mass finishing and polishing processes. At the same time, the impact of stainless steel media can improve the surface strength of product parts and repair surface defects.

  • 2. What are the uses of stainless steel media?
  • Stainless steel media are widely used in the finishing and polishing industry of tumbling, vibrating, mass finishing and polishing. Specific applications are as follows:

    2.1 Deburring. Stainless steel media also have the function of removing burrs. Some small burrs and sharp teeth on the edges of parts and hole walls can be chamfered and flattened by scraping with stainless steel media with sharp corners or edges to achieve the effect of removing burrs.

    2.1 Turning tool marks removing. This process is similar to deburring. The turning tool marks left after the machining of parts can be removed by the impact and scraping of stainless steel media.

    2.2 Polishing. The main function of stainless steel media is to brighten the surface of product workpieces. Through the tumbling and rotating motion of the machine, the high density stainless steel media impacts the surface of the part, changing the metallographic structure of the metal surface layer. The arrangement of the metal grains is reorganized to form a dense layer, which enhances the diffuse reflection of light, making the surface Becomes shiny and sparkling, achieving a near-mirror polished effect.

    2.3 Degreasing. Through the combined use of stainless steel media and cleaning liquid, dust, sludge, and grease on the internal and external surfaces of parts can be removed. Manual cleaning of oil stains is a time-consuming and labor-intensive process. Using a tumbling finishing machine and stainless steel media for cleaning can improve the brightness and gloss of the surface of the parts while removing oil and stains. It is a process that gets twice the result with half the effort.

  • 9. Which finishing and polishing machine is suitable forv stainless steel media?
  • ShineTec recommends using a vibratory polishing machine with stainless steel media for polishing. The reasons are as follows:

    9.1 To achieve a good polishing effect with stainless steel media, the product parts need to be put into as much tumbling media as possible. The vibratory finishing machine can be equipped with a high-power vibration motor and a large-capacity working chamber to obtain a larger amplitude, allowing the workpiece to fully tumble in the machine and collide with the abrasive media to obtain a better surface effect.

    9.2 Because the size of the centrifugal barrel is limited, the centrifugal barrel finishing machine has a small loading capacity of tumbling media and is not very efficient. Moreover, due to the large proportion of stainless steel media, the centrifugal force generated when the barrel is loaded with abrasive media and rotates at high speed will increase many times, which greatly exceeds the design strength of the centrifugal barrel finishing machine and creates potential safety risks.

    9.3 The barrel of the centrifugal disc finishing machine also does not meet the capacity requirements compared to the vibrating finishing machine. If it is operated at full load, it will greatly exceed the design strength of the machine, and it is not suitable to use stainless steel media to polish product parts.

    9.4 The polishing efficiency of the tumbling barrel finishing machine is too slow, and the design capability of the machine itself is not suitable for heavy-duty use, and it is not suitable for polishing with stainless steel media.

  • 10. What are the benefits of polishing with stainless steel media?
  • If you don’t know how to improve the surface gloss and brightness of metal product parts and workpieces, then using stainless steel media for tumbling and polishing is the best polishing process and method.

    10.1 High polishing efficiency. Compared with polishing media such as high-alumina porcelain media, high-density porcelain media, and zirconia balls, stainless steel media have the highest specific density (7.8 g/cm3) and can obtain the highest brightness in the shortest time.

    10.2 High cleaning efficiency. Stainless steel media have very little wear and do not pollute the surface structure of metal product parts. With the assistance of cleaning agents and brighteners, they can fully clean away oil, sludge, and impurities on the surface of workpieces automatically, in large quantities, quickly, and solve the problem of manual cleaning. Time-consuming and labor-intensive problem.

    10.3 Non-destructive polishing. 不Stainless steel media have no cutting force, will not finish the surface with great force, and will not affect the dimensional accuracy of the product. It is a non-destructive polishing process.

    10.4 Extra long service life. Stainless steel media have almost no wear, and a single purchase can last almost a lifetime. There is almost no wear cost, which can greatly reduce your direct polishing costs.

    10.5 Easy to use. Ceramic polishing media will stick to each other, break, and become dirty after use. They need to be fully self-polished and cleaned before they can be used again. There are no breakage or bonding issues with the stainless steel media. After polishing, you only need to simply rinse it with water and it can be used continuously again.
  • 11. Do stainless steel media require maintenance for daily use?
  • Good maintenance habits can extend the service life of stainless steel media. Although stainless steel media is an tumbling polishing media that is easy to use and store, its service life will be accelerated if not properly maintained.

    11.1 Correct usage. After polishing, if it is not used for a long time, you need to rinse the stainless steel media with water and dry it before storing it.

    11.2 Proper mixing ratio of stainless steel media, product parts and polishing liquid. A corresponding ratio needs to be maintained among the above three. In order to save procurement costs, many people want to use as little stainless steel media as possible and put more product workpieces. However, too little abrasives will cause the product parts to collide with each other during polishing or the workpieces to directly scratch the working chamber wall of the machine and damage the lining PU. This results in reduced polishing efficiency, reduced polishing quality and possible damage to product parts and machines.

    11.3 Replacement of damaged stainless steel media. Ensure that every one of stainless steel media in the machine is intact. If some of the media are deformed or damaged, the damaged media must be replaced immediately. The damaged media surface will produce cracks, edges, and cutting edges. These parts will affect the surface effect of product parts during polishing, and even damage the product.

  • 12. In which industries can stainless steel media be used for product parts and workpieces?
  • Stainless steel abrasives can be used for finishing and polishing metal parts or workpieces in most industries.

  • Yes, stainless steel media can be used to polish nickel plated metal parts. However, the polishing time needs to be shortened to 40-60% of the ordinary polishing time.
  • 17. Can stainless steel media be used for dry and wet finishing?
  • Stainless steel media cannot be used for dry polishing. During the polishing process of product parts, metal shavings, oil stains and other impurities will be produced. If these sludge is not cleaned during the finishing process, it will adhere to the surface of the product to form a layer of oil stains, making the parts black and dull. The result is that the workpiece will become darker. The darker you throw it, the brighter it will never be.
  • 18. Do stainless steel media need to be dried when stored?
  • If you need to store it for a long period of time, such as months or years, you need to let the stainless steel media dry before packaging and storage. If it is for a short period of time, it is not necessary because stainless steel itself is rust-proof and anti-corrosion.

  • 26. Why does the surface of the part become darker and lose its luster after being polished with stainless steel media?
  • When polishing with stainless steel media, it is found that the surface of the part becomes black and dark because the oil on the surface of the media or the carbon in the impurities is deposited on the surface of the product. The solution is to clean the stainless steel media with cleaning liquid before polishing.
  • 27. Which stainless steel media should I buy?
  • 27.1 Choose the appropriate stainless steel media according to the shape and size of your product parts and workpieces. Please do not use large-sized media to polish small-sized parts to avoid damage. If you use small-sized media to polish large-sized parts, it will take more man-hours and have a big impact on the service life of the media.

    27.2 Make sure that the internal and external surfaces of your parts, as well as holes, gaps, corners, etc., can be polished with stainless steel media.

    27.3 According to the actual usage environment of your product. If your use environment contains acid and alkaline substances, you need to choose high-grade stainless steel media. The following is the corrosion resistance of various grades of stainless steel media:

    440C < 420 < 302 < 304 < 316
  • 28. Why do my product parts turn black after being polished with stainless steel media?
  • The main reason is that the stainless steel media needs to be pre-cleaned before polishing. If there are some residual brighteners, sludge, debris and other impurities attached to the media surface after the last polishing, polishing again will contaminate your product parts with these impurities, causing the product surface to turn black.
  • 29. Do stainless steel media need to be cleaned before each use?
  • We recommend cleaning stainless steel media once before use. This ensures that the surface of the part will not turn black or dull during the polishing process.
  • 30. How much stainless steel media is required to complete a polishing process?
  • Depending on the machine capacity used. It is recommended that the total volume of materials does not exceed 2/3 of the working chamber.

About Polishing Media

  • 1. What’s the polishing media?
  • polishing media, also called polishing chip, polishing stone, and vibratory polishing media. Compared with ceramic deburring media, polishing media are a kind of abrasive media that does not contain abrasive sand with finishing function. Its main function is to improve the gloss and brightness of the surface of product parts. Its operating principle is to use its own pressure with high density to hit the surface of the product during the tumbling, rolling, throwing and rotating processes, changing the grain structure of the surface of the workpiece to form a dense layer, thereby achieving a shiny decorative effect on the surface.
    ShineTec's porcelain media
  • 2. What are the polishing media?
  • Polishing media are classified according to materials into porcelain media, stainless steel media, and bio-degradable polishing media.

    2.1 Porcelain media. Porcelain media are artificially made mass abrasives with various shapes, shaped like stones, so they are also called polishing stones. There are high-alumina porcelain media, high-density porcelain media, and zirconium bead polishing media.
    The main component of high-alumina porcelain media is alumina. Its appearance and internal physical properties are similar to those of porcelain bowls used for eating at home. They are generally white, hard in texture, and have a specific density of up to 2.6 g/cm3, and the ceramic media for deburring has a specific density of about 2.3 g/cm3. There is a significant difference in weight between the two.
    The material of high-density porcelain media is actually the same as that of high-alumina porcelain media, except that the proportion of alumina power contained in it is higher, up to more than 95%, so the specific density is larger than that of high-alumina porcelain media, up to 2.9 g/cm3, the surface of the polished workpiece is brighter than that of high alumina porcelain.
    Zirconium polishing bead use zirconia powder or zirconium silicate powder instead of alumina powder. The main shape is spherical ball. Due to different materials, they are generally called zirconia beads, zirconia balls or zirconium silicate beads, zirconium silicate balls. The density can reach 6.0 g/cm3 and 4.0 g/cm3 respectively, which shows that the surface brightness of the polished workpiece product is even higher.

    2.2 Stainless steel polishing media. Mainly produced from stainless steel, the materials are divided into 201, 304, 316, 316L, 402, etc., and are used in environments with different anti-corrosion requirements. It is required that the polished workpiece be a metal product, and non-metallic workpieces will have no effect. The shapes include spherical, ballcone, ufo, pins, angle cut cylinder, etc. Because the shape has sharp corners or edges, it can touch holes, seams, corners and other parts of product parts to achieve polishing of the internal and external surfaces.

    2.3 bio-degradable polishing media. It uses the crude fibers of animal and plant materials and the oil contained in them to polish, imitating the cloth wheel and adding polishing paste for polishing, which can achieve a mirror polishing effect. At present, the most widely used materials include corn cobs, walnut shells, wood pellets, bamboo chips, sawdust, shredded felt, shredded leather and other materials. This kind of mirror polishing method generally uses a barrel (tumbler) polishing machine to dry polish without adding water. The workpiece after initial polishing or fine polishing is put into the barrel together with the biological polishing media, and an appropriate amount of polishing paste is added. It may take more than ten hours, and the final result will be sparkling, close to the mirror polishing effect of a handmade cloth wheel.

  • 3. How to choose the appropriate polishing media?
  • 3.1 Depending on the material of the product parts that need to be polished. The harder the workpiece itself is, the higher the hardness of the polishing media required. In layman’s terms, only head-on confrontation will produce results. The harder the polishing media, the better the polishing effect. The following is the order of hardness of various polishing media:
    High alumina porcelain media < High density porcelain media < Zirconium silicate ball polishing media < Zirconia ball polishing media < Stainless steel polishing media.
    3.2 According to the shape of the polishing media. The following is a comparison of the polishing effects of different shapes of polishing media: spherical > oval > cylindrical > triangular.

    3.3 Some metal workpieces or non-metallic parts require a barrel polishing process, so bio-degradable polishing media must be selected.

  • 4. Is polishing media expensive?
  • The price of polishing media is much higher than the price of deburring ceramic media for rough or fine finishing. The price generally ranges from more than five dollars to tens of dollar per kilogram, but its wear resistance is several times higher than that of deburring media. Like stainless steel polishing media, it can be said that there is basically no wear and tear. You can buy it once and use it for life. Therefore, in terms of unit wear cost, the use cost of polishing media is low.
  • 5. What is the service life of the polishing porcelain media?
  • The higher the hardness of polishing media, the stronger the wear resistance. Generally speaking, the service life of polishing media is at least one year. The polishing media produced by ShineTec are durable abrasives that have been fired through dozens of sample tests using exclusive process formulas. After wear resistance testing, the wear resistance of our polishing media is comparable to the performance of world-renowned manufacturers such as German Roesler and Japanese manufacturer Tipton. If you don’t know where to find the best polishing media, you can take a closer look at our ShineTec products.
  • 6. Is it necessary to add polishing compounds when using polishing media?
  • Polishing compound is a product that does not contain sulfur, phosphorus, or chlorine additives Water-soluble polishing liquid, also called polishing liquid, brighteners, have good degreasing, rust-proof, cleaning and gloss-enhancing properties, and can make metal products show true metallic luster. It has the advantages of stable performance, non-toxicity and no pollution to the environment. Adding an appropriate amount of polishing compound during polishing can improve the polishing efficiency and effect. It has a significant effect on the surface polishing of stainless steel, aluminum alloy, copper and other products, so it must be added.

    6.1 Softening effect. Polishing compound can soften the oxide film on the surface of metal products and is easily removed by polishing media to accelerate polishing.

    6.2 Lubricating effect. Polishing compound can provide lubrication. It acts as a lubrication between polishing media and metal parts to reduce scratches on the surface of the workpiece caused by impurity particles.

    6.3 Cleansing effect. Polishing compound can clean the oil stains on the surface of the workpiece and restore the original luster of the metal.

    6.4 Buffering effect. The tumbling motion of polishing compound and water in the polishing machine can buffer the collision between workpieces and polishing media and protect the workpiece.

    6.5 Anti-rust and anti-corrosion effect. Parts treated with polishing compound can have anti-rust and anti-corrosion effects in a short period of time. Of course, the best anti-rust measure is to treat it with anti-rust agent and then dry it.

  • 7. What are the functions of different types of polishing media?
  • Usually, hard polishing media are used when polishing metal parts, such as high-alumina porcelain media, high-density porcelain media, zirconium balls, stainless steel and other abrasives. Marble polishing should choose high-alumina porcelain polishing media. It is best to choose zirconium ball polishing media for metal mold polishing. Soft parts such as plastics are polished using a mixture of bio-degradable media and hard media.
  • 8. What effect does the shape, size and angle of polishing media have on the polishing effect?
  • The smoother the surface of the polishing media, the better the polishing effect on the parts. Therefore, when polishing, choose spherical polishing media as much as possible. The size of the media should be smaller than 1/3 of the inner hole of the part, but not too small to prevent the hole from being blocked by the media.
    Some parts with edges, folds, steps, etc. can be mixed with spherical polishing media and polishing media with sharp corners or edges, so that parts that cannot be touched by balls can be polished.
    Polishing media exceeding 80mm will not have very good brightness after polishing, so the size of the polishing media selected is generally below 80mm.

    polishing media selection
  • 9. What is the difference between the polishing effects of natural polishing abrasives and polishing media?
  • Natural polishing media refer to abrasives obtained directly from nature without artificial processing, such as quartz sand, pebbles, garnets, etc. Because of their size and materials, their application range is very narrow, and it is difficult to obtain a satisfactory surface effect when polishing. Artificial polishing media are customized according to the shape and material of the parts. The products are rich in variety and specifications, and can quickly obtain satisfactory surface quality.
What is the ceramic media?

About Ceramic Media

  • 1. What is the ceramic media?
  • Ceramic media is used for tumbling finishing and polishing of product parts and workpieces, also called tumbler media, vibratory media, tumbling chip. It is a melting reaction between sand powder abrasives (such as brown corundum abrasive sand, white corundum abrasive sand, chrome corundum abrasive sand, silicon carbide abrasive sand, alumina powder, zirconia powder, etc.) and other ceramic bonding agents at high temperatures, artificially sintered mass finishing and polishing materials with various shapes. Because its hardness is close to that of stone, it is called tumbling stone. It can repair defects on the product surface, improve surface physical properties, and has a variety of finishing or polishing uses.

  • 2. What types of ceramic media are there?
  • There are many types of ceramic media, each suitable for different surface treatment purposes.
    Depending on the type of sintered abrasive sand powder, the commonly used ones are ceramic deburring media, silicon carbide deburring media, White corundum finishing media, chrome corundum finishing media, porcelain polishing media, High density porcelain media, zirconia polishing ball, Resin media.
    According to the use effect, there are rough finishing media, fine finishing media and polishing media. Both rough and fine finishing media have cutting force, but the cutting force is divided into light and heavy. The polishing media does not have cutting force and is only used to improve the surface gloss and brightness of the workpiece.
    According to the material, there are ceramic media and resin media. Among them, ceramic media are the collective name for deburring media such as brown corundum, silicon carbide, white corundum, chrome corundum, high-aluminum porcelain, high-density porcelain, and zirconia abrasive media.

  • 3. What is the use of ceramic media?
  • The operating principle of the ceramic media is to mix the workpiece or part with the tumbling media, add an appropriate amount of water and finishing compound, and load it into tumbling finishing machine In the working barrel, mechanical movements such as tumbling and rotation are carried out through vibratory (vibration), centrifugal disc, barrel, and tumbling barrel, so that the ceramic media and the workpiece impact and rub against each other, finishing the surface to achieve the effect of deburring and polishing.
    The role of ceramic media is reflected in two aspects:
    The ceramic media with cutting force can perform functions such as deburring, descaling, deflashing, chamfering, derusting, degreasing, cleaning and smoothing of parts and workpieces.
    The ceramic media without cutting force improves the density of the skin layer by impacting the product surface, and can polish and brighten the surface of parts and workpieces.

  • 4. How long is the service life of the ceramic media?
  • The service life of a ceramic media can usually be from a few months to a few years, depending on the hardness, shape, and size of the finishing workpiece. Workpieces with sharp burrs and edges, sharp edges, flash edges, higher hardness and larger appearance will cause greater loss to the media. The service life is shorter.
    Of course the most basic factor depends on the quality of the ceramic media. High-quality tumbling media will enhance wear resistance while ensuring finishing efficiency. ShineTec’s ceramic media is a mature and stable formula formed on the basis of dozens of process tests. Corundum sand and ceramic bonding agent have the strongest matching performance, and the wear resistance of the product is longer than other products on the market in terms of service life. There is a 3 times improvement.
  • 5. What are the different functions of ceramic media made of different materials?
  • 5.1 Brown corundum deburring media is suitable for finishing and cutting product workpieces made of general metal or non-metal materials such as burrs, oxide scales, flash edges, turning tool marks, cutting edges, mold closing lines, etc.

    5.2 Silicon carbide deburring media are suitable for finishing and cutting hard, highly brittle and low-strength materials, such as cast iron, brass, bronze, zinc, tin and other products, especially magnetic materials such as rubidium iron boron, with very good results.

    5.3 White corundum and chrome corundum deburring media are suitable for finishing and cutting some precision parts and components because of their fine grit size. Also, because of their low surface roughness after treatment, they also form a very bright surface effect, so It is often used to finish and polish these products in one process at the same time.

    5.4 High alumina porcelain polishing media do not contain abrasive sand inside, so they have no deburring effect. The main component is alumina powder. The abrasive has high density. When it moves with the workpiece, it has a strong impact on the surface of the workpiece, forming a thick surface dense layer, which can improve the surface gloss and brightness of the part.

    5.5 The function of high-density porcelain polishing media is the same as that of high-alumina porcelain media. The difference is that the content of alumina powder in high-density porcelain media is higher, and its alumina content can reach more than 95%. Therefore, the density is larger, forming the surface brightness is higher.

    5.6 There is no abrasive sand inside the zirconia polishing ball. The main component is zirconia powder. The density of the zirconia media is higher than that of high-density porcelain media. The surface brightness of the workpiece after natural treatment is the highest.

    5.7 Resin media contain abrasive sand inside. Depending on the grit size of the sand, they can be divided into heavy cutting, medium cutting, and light cutting. They are suitable for finishing some soft metal workpieces, such as aluminum alloy products.

  • 6. What is the finishing efficiency of the ceramic media?
  • The finishing efficiency of the ceramic media depends on the grit size of the abrasive sand contained in it and the type of deburring and finishing machine. Specifically in terms of finishing time, the time required for a single finishing treatment can range from a few minutes to a few hours.
    The larger the grit size of the abrasive sand, the stronger the cutting force and the higher the finishing efficiency. But the larger the grit size, the greater the surface roughness and therefore the worse the surface finish.
    Depending on the operation mode and speed of the tumbling finishing machine, the finishing efficiency can be arranged in the following order:
    centrifugal disc finishing machine > centrifugal barrel finishing machine > vibratory finishing machine > tumbling barrel finishing machine
    In addition, for the same type of machine, the larger the machine, the larger the volume of the working barrel, and the higher the finishing efficiency.

  • 7. Does the shape and size of the ceramic media affect its finishing performance?
  • The shape and size of the ceramic media are key factors affecting finishing performance. The purpose of making the ceramic media into shapes such as triangles, cubes, spheres, cylinders, and three-star shapes is to make certain sharp corners, cut surfaces, and curved surfaces of the ceramic media better match the irregular and complex shapes of product parts, so that some parts that are difficult to reach can be parts can also be polished. If the selection of the ceramic media is incorrect, some parts will never be polished, which will definitely affect the finishing performance.
    The size of the ceramic media is also an important factor to consider. If the size is too large, it will also cause the inner holes, dead corners, gaps and other parts of the workpiece to be unable to be polished. If the size is too small, on the one hand, it will cause the abrasive to wear too fast, and on the other hand, it will block certain holes in the product, and may even result in defective products.

  • 8. What are the benefits of finishing and polishing with ceramic media?
  • Are you still looking for manual polishing methods? Let us recommend to you this large-volume, high-efficiency automatic finishing and polishing process. Its comparative advantages over manual finishing methods are as follows:

    8.1 Compared with manual finishing and deburring, the efficiency can be improved dozens of times. Using some large-scale tumbling finishing machines, ceramic media mixed workpieces can feed hundreds or even thousands of kilograms at a time, and can be completed within dozens of minutes or hours. This processing efficiency is incomparable to manual polishing.

    8.2 The surface effect after finishing is uniform and controllable. The quality of hand polishing depends on the personal skill proficiency of the worker. Some products may have burrs polished cleanly, while others may still have some residue. The surface quality of each product is different. Sometimes it may also cause product damage, resulting in a relatively high scrap rate.

    8.3 The running costs of tumbling finishing are extremely low. The one-time purchase cost of the machine starts from a few thousand dollars, and it can generally be used for many years. The choice of ordinary ceramic media depends on the actual conditions of the product parts that need to be processed, and the price ranges from a few dollars to more than ten dollars per kilogram. Buying a few hundred kilograms at a time can usually take several months. The amount of polishing compound is very small and the cost is almost negligible.
    Ordinary finishing machines can feed dozens of kilograms of workpieces at a time, and the finishing time for a batch is generally 30-60 minutes. The direct cost of finishing and polishing when evenly distributed to each product is minimal.
    On the other hand, in terms of saving labor costs, the advantage of using ceramic media for batch deburring and polishing is even greater. As long as workers need to handle it when loading and unloading materials, the machine can be operated unattended, which greatly saves labor costs.

    8.4 By customizing ceramic media with special shapes and sizes, they can be used to process some deburring and polishing areas that cannot be completed by manual finishing. They have powerful functions and wide applicability.

    8.5 It is a safe and environmentally friendly deburring and polishing process. Compared with processes such as chemical polishing and electrolytic polishing, the sludge produced by ceramic media can be directly treated as solid waste after filter press, which is environmentally friendly.
  • 9. Can the ceramic media be used for dry finishing?
  • Not allowed.

    The water and finishing compound during the polishing process can provide lubrication. Buffer the impact force generated by the workpiece and ceramic media during high-speed movement. Without the lubrication and buffering effects of water and finishing liquid, the debris and impurities shed during the finishing process will scratch the surface of the workpiece and leave pits on the surface.

    At the same time, these metal or non-metal debris and impurities will accelerate the wear of the PU lining in the working barrel, greatly increase the temperature rise generated during work, and greatly reduce the service life of the PU.
    If the dust generated during the grinding process is not moistened with water, it will produce dust and pollute the surrounding air and environment.
  • 10. What kind of ceramic media is the best quality?
  • If you don’t know where to find the best ceramic media, here are some tips to help you decide:

    10.1 The shape of the ceramic media. The forming process in the production process of ceramic media is a link that reflects the manufacturing process level of the manufacturer. Good quality control capabilities determine that the ceramic media’s mixing, mud refining, shaping, cutting, and sintering processes all have qualified quality control capabilities. The ceramic media produced in this way have uniform shapes, consistent sizes, smooth surfaces, and sharp corners, these performance indicators ensure that cracks, mud occur rarely.

    10.2 The hardness of the ceramic media. This indicator reflects the sintering temperature control level of the kiln. If the kiln temperature is too low, the melting reaction of various micro-powders inside the ceramic media is insufficient, the tumbling media is too tender, the hardness is not up to standard, and the wear is very high during use. If the kiln temperature is too high, it will cause over-burning. Corundum sand on the surface of the ceramic media will precipitate, resulting in a porridge-like surface and the product will be scrapped.

    10.3 Durablity of ceramic media. Excellent product raw material quality, strict production process control, and just the right formula combination can produce high-quality ceramic media. The wear resistance of ShineTec’s tumbling media can reach about 3 times that of other manufacturers on the market. You can compare the use cost, which can reduce the direct cost of your product finishing and polishing process by 3 times.

  • 11. How to choose a suitable ceramic media?
  • 11.1 Choose the material of your ceramic media based on the effect you want to achieve. If you want to deburr, descale, deflash, derust, chamfer and other finishing effects on your product parts, then you should choose ceramic deburring media, silicon carbide deburring media, white Corundum finishing media and chrome corundum finishing media are abrasives with cutting force. If you just want to improve the surface brightness of your product, you need to choose polishing porcelain media, high-density porcelain media, and zirconia polishing bead, which are non-cutting and high-density tumbling ceramic media. If your product is made of soft metals such as aluminum alloy, copper, and zinc, you need to choose a resin media.

    11.2 Choose the appropriate ceramic media based on the size and surface condition of your product. If your product does not have holes, or cracks, then choose a larger deburring media so that it has a long service life and will not produce stuck holes or clogging even after its shape becomes smaller.

    11.3 Choose the appropriate ceramic media based on surface roughness. For rough products, choose a tumbling media with strong cutting force and sharp product corners. For precision parts, choose a abrasive media with fine abrasive grit and low cutting force.

About Finishing Media

  • 1. What is the finishing media?
  • All materials that are naturally produced or artificially produced and have high hardness, cutting ability and certain strength and toughness, and are used for grinding, finishing or polishing, can be finishing media, abrasive media. Finishing media are a diverse category, and many people have questions of one kind or another, such as: What are finishing media? What are the commonly used finishing media? What are finishing media used for? What are the types of finishing media? Let’s talk about these issues in detail below.
    natural abrasives
  • 2. What are the types and uses of commonly used finishing media?
  • According to the source, abrasives can be divided into two categories: natural abrasive media and artificial finishing media.

    2.1 Natural abrasive media include diamond, natural corundum (also called emery), garnet, quartz sand, diatomaceous earth, pumice, flint, silica, feldspar, chalk, lime for polishing, etc.

    2.1.1 Diamond. Diamond is the hardest substance currently known. The main ingredient is carbon, which is expensive because of its limited origin. Mainly used for manufacturing resin, ceramic or metal bonded abrasive tools. Diamond has a sharp shape and is the best abrasive tool for grinding hard and brittle materials such as cemented carbide, optical glass, and ceramics. It has a better polishing effect on alloys of different phases with huge differences in soft and hard. In addition, diamond polishing abrasive media have the characteristics of long finishing life, high cutting ability, and strong wear resistance. However, because it is easily carbonized at 700℃~800℃, it is not suitable for finishing steel materials and ultra-high-speed grinding.

    2.1.2 The main components of emery are aluminum oxide (Al2O3), a small amount of iron oxide (Fe2O3) and other impurities. It can be used for finishing and polishing all metals.

    2.1.3 Garnet is the oldest type of polishing abrasive media. It was called Ziyawu in ancient China. It has been used to grind gemstones since the Bronze Age. It gets its name because the crystal particles are shaped like pomegranate seeds. It is mostly used for sandblasting, waterjet cutting, manufacturing coated abrasive tools, filter materials, wear-resistant floor aggregates, etc. It is used in hardware, steel, castings, ceramics, aluminum, wood, and leather industries.

    2.1.4 The main component of quartz sand is SiO2, which is the earliest grinding wheel material and can be used for grinding, polishing, tumbling and sandblasting. The main component of diatomite is also SiO2, which is an ingredient in the manufacture of polishing powder and whetstone. Suitable for finishing and polishing soft metals such as brass, aluminum, and zinc.

    2.1.5 Pumice comes from volcanoes and is the raw material for making polishing powder. Suitable for finishing and polishing soft metals and their alloys, wood, glass, plastic, leather, etc.

    2.1.6 Flint, is a relatively common siliceous rock. Because flint is hard and produces sharp fractures when broken, it was first favored by primitive people in the Stone Age and used to strike and make stone tools. The striking of flint and iron tools will produce sparks, so it was also used as a fire-making tool by ancient people. In ancient China, a small piece of flint and a steel “fire sickle” were often struck to make fire, so flint is also called flint. The modern grinding industry utilizes its hard and sharp edges as grinding materials.

    2.1.7 Silica is the general name for vein quartz, quartzite, and quartz sandstone. The main component is also SiO2. Silica has a wide range of uses. When used in the grinding industry, it can be used to make grinding stones, oil stones, and sandpaper. It can also be used to polish glass, Surface of metal products, sawing and grinding stones, polishing jewelry, etc.

    2.1.8 Feldspar is the general name for feldspar minerals. There are many types, such as albite, anorthite, barium feldspar, barium adolite, microcline feldspar, orthoclase, feldspar, etc. The main component is feldspar. Silicon oxide, aluminum oxide, K2O, sodium oxide, calcium oxide, etc. When used in the grinding industry, it is often used as a bond component in the production of bonded abrasive tools, such as grinding wheels.

    2.1.9 Chalk is calcium carbonate and has a wide range of uses. It is used in the grinding industry as a raw material for tooth powder, toothpaste and other cosmetics.


    2.2 Artificial abrasive media. It is an abrasive material that does not exist in nature and is entirely artificially produced. The main types are:

    2.2.1 Sintered abrasives. Mainly divided into corundum abrasive media, silicon carbide abrasive media and CBN (cubic boron nitride) abrasive media, the varieties are divided into:

    Brown corundum abrasive media. The main component is Al2O3, which has medium hardness, high toughness, sharp particles, relatively low price, and is suitable for processing metals with high tensile strength.

    White corundum abrasive media. Its hardness is slightly higher than brown corundum, but its toughness is poor. It is easy to cut into the workpiece during finishing. It has good self-sharpening, low heat generation, strong finishing ability and high efficiency. Chrome corundum abrasive media is its derivative.

    Single crystal corundum abrasive media. Its particles are composed of a single crystal and have good multi-edge cutting edges, high hardness and toughness, strong grinding ability, and low grinding heat. The disadvantage is that the production cost is high and the output is low, so the price is relatively high.

    Silicon carbide abrasive media. Divided into black silicon carbide abrasives, green silicon carbide abrasives, cubic silicon carbide abrasives, and cerium silicon carbide abrasives. The main component is SiC, which has high hardness, high brittleness, sharp abrasive grains, good thermal conductivity, and strong wear resistance. It is more suitable for processing hard and brittle metal and non-metallic products. At present, the finishing and cutting of most NdFeB magnetic materials is widely used.

    CBN (cubic boron nitride) abrasive media. It is a synthetic super-hard material, its hardness is second only to diamond, and it is an excellent grinding material. Compared with traditional grinding materials, CBN abrasives have excellent grinding performance, especially when grinding cemented carbide, and are more efficient. CBN abrasive media are known as one of the greatest technological advances in the history of the abrasives industry due to their high strength, high wear resistance, excellent hardness close to diamond, and excellent thermal stability. The wear resistance and hardness are more than four times that of traditional abrasives, and its unique chemical properties also make it particularly suitable for grinding ferrous metal materials.
    The thermal integrity of CBN abrasive media and their ability to maintain a sharp cutting edge when machining ferrous materials makes them the product of choice for advanced grinding systems. When grinding ferrous metals, they do not react with each other; when grinding steel alloys, they are not easily oxidized. This makes CBN abrasive media the first choice for high-performance grinding wheels for grinding different materials such as cast iron and hard steel.
    CBN abrasive media can withstand high temperatures of 1300℃~1400℃, are chemically inert to iron group elements, have good thermal conductivity, have high removal rates when grinding steel, have large grinding ratios, and have long tool life. They are ideal for grinding hardened steel, The best abrasive for metals with high hardness and toughness such as high-speed steel, high-strength steel, stainless steel and heat-resistant alloys. In addition, CBN abrasive tools are also suitable for ultra-high-speed grinding, and metal-based CBN abrasive tools will not break even if the linear speed exceeds 250m/s.


    2.2.2 Preformed finishing media.
    There are two types of such finishing media: One is sintered ceramic media; also known as ceramic deburring or polishing media. Corundum sand or silicon carbide powder, quartz powder, alumina and other materials are melted at a high temperature of more than 1,000 degrees and sintered into a finishing media with very high hardness. The other is abrasives media bonded with resin, called resin media, polyester media or plastic media. This type of abrasives media can be made into triangular, spherical, square, conical, cylindrical and other shapes. Each shape of abrasives media has different sizes.


    2.2.3 Steel finishing media.
    It can be made into hard steel balls, stainless steel balls, ballcone, ufo, needles, pins, angle cut cylinder and other shapes. This type of abrasive media has high strength and is not easily broken. It is mainly used for polishing surface brightness.


    2.2.4 Bio-degradable finishing media.
    Commonly used ones include corn cobs, walnut shells, sawdust, shredded felt, shredded leather, etc. It is mainly used in the tumble polishing process. It is used for the final polishing and drying of parts that have been treated with light finishes, and can achieve an effect close to mirror polishing.

  • 3. What is tumbling finishing media?
  • Tumbling finishing mediaalso called tumbling abrasive media and mass finishing media, refer to abrasive media that use tumbling, vibrating, rotating and other motion methods to finishing the surfaces of product parts and workpieces. It can be natural abrasive media such as river sand, stones, and plants, but most of them use artificial abrasives, including abrasive media with cutting force and polishing media without cutting force. This artificial abrasive media comes in a variety of shapes, including tri-angle, ellipses, spheres, cylinders, tri-star shapes and other clumps, so it is also commonly called tumbling media. It can be said that tumbling abrasive media are one category of abrasive media, but because natural abrasive media are rarely used now, tumbling media actually refer to tumbling abrasive media in most cases.

  • 4. What can tumbling finishing media be used for?
  • Tumbling media can deburr, descale, deflash, chamfer, derust, degrease, clean, polish, brighten on metal and non-metallic parts and workpieces. The advantage of this kind of finishing media is that it can quickly finish products in large quantities, automatically, and has the characteristics of low cost, high efficiency, safety and environmental protection.
  • 5. What are the types of tumbling finishing media?
  • Tumbling media are divided into three types of abrasive media: rough finishing, fine finishing and polishing:

    5.1 Rough finishing media, mainly includes brown corundum ceramic media, resin ( plastic) media, divided into heavy cutting force, medium cutting force and light cutting force.

    5.2 Fine finishing media, includes white corundum ceramic media, chrome corundum ceramic media, 3P abrasive media, etc. Because the grit size of the micropowder contained in it is very fine, some of which are nearly 2000-3000 mesh, it can continuously perform micro-cutting on the surface of the workpiece to form a more delicate surface roughness, which is suitable for finishing and polishing precision parts.

    5.3 Polishing abrasive media include high-alumina porcelain media, high-density porcelain media (high-alumina porcelain media with an alumina content of more than 95%), stainless steel media, walnut shell abrasive media, corn cob abrasive media, etc. The main purpose is to improve the gloss and brightness of the workpiece surface.

  • 6. How does tumbling finishing media work?
  • The shapes of tumbling finishing media include triangles, spheres, cubes, cylinders, three-star shapes, etc. The cutting surfaces are straight and angle to form acute angles at different angles. The specifications are also available in dozens of sizes from 1mm to 60mm, which are suitable for each. Finishing and polishing of internal and external surfaces of product parts with irregular and complex shapes, holes, seams, corners and other parts. The main mode of operation is to put the abrasive media and parts together into the working barrel of the tumbling finishing and polishing machine, and use the vibrating, tumbling, rotating and other mechanical movements generated by the machine to cause the abrasives to rub and cut on the surface of the workpiece to achieve the effect of finishing and polishing.

  • 7. How to choose the correct tumbling finishing media?
  • There are several factors to consider when purchasing tumbling media:

    7.1 Cutting force. This indicator determines the speed at which the workpiece is ground. Heavy-cutting abrasive media can finish parts faster but produce a relatively rough surface finish. Conversely, light-cutting abrasive media finish more slowly but produce higher surface quality.

    7.2 Durability. Wear resistance determines the service life of abrasive media. Wear resistance is affected by factors such as the quality of various raw materials, the particle size and content of abrasives, the matching degree of binder and corundum sand, the condition of vacuum during molding, and the control of sintering temperature. This is a key indicator reflecting the quality of abrasives.

    7.3 Hardness. Workpieces with different hardnesses require tumbling media with different hardnesses for finishing. The harder the workpiece, the harder the abrasive media is required to polish it. If high-hardness abrasives are used to polish workpieces made of soft materials, they may cause damage to the workpiece. For example, if aluminum alloy workpieces are ground with brown corundum ceramic deburring media, the surface will be dull, corrosion pits (impacting points) and a deformation disturbing layer will be produced on the surface.

    7.4 Shape and size. Different shapes and sizes of product parts require matching abrasive media of different sizes and shapes. Generally speaking, the larger your workpiece is, the larger the media will be, and the smaller the workpiece will be, the smaller the abrasive will be. Particular attention should be paid to the shape and size of the abrasive media so that it cannot get stuck in the inner holes, pipes, gaps, corners, etc. of your product.
    Every user of abrasive media wants to buy high-quality abrasives with fast grinding time, high surface quality and strong wear resistance. Maybe you are looking for where is the best tumbling abrasive media manufacturer? Please contact us. ShineTec masters the key technologies of abrasive production and manufacturing and can provide you with the most cost-effective abrasive media.
  • 8. What is the best tumbling finishing media?
  • To measure the quality of finishing media, the most critical factors are cutting efficiency and wear resistance. However, in terms of production and manufacturing processes, these two are contradictory indicators. To achieve high cutting efficiency, you need to use large-grained corundum sand. However, the larger the particle size of the sand, the easier it is to fall off from the matrix during finishing, affecting the wear resistance of the abrasive and causing high wear. Here it is necessary to master the bonding strength between the sand grains and the binder, find a balance point, and maximize the cutting force of corundum sand while enhancing the bonding strength with the matrix. It requires both high cutting force and strong wear resistance. This is the core technology that produces the best tumbling media.

  • 9. How long is the service life of tumbling finishing media?
  • The service life of tumbler media typically ranges from several months to several years, depending on the hardness, shape, and size of the workpiece being ground. Workpieces with sharp burrs and edges, sharp edges, flash edges, higher hardness and larger appearance will cause greater loss to the abrasive. The service life is shorter.
    Of course the most basic factor depends on the quality of the tumbler media. Good abrasive media will enhance wear resistance while ensuring grinding efficiency. ShineTec’s tumbler media are mature and stable formulas formed on the basis of dozens of process formula tests. Corundum sand has the best material match with other binders, and the wear resistance of the products is longer than other products on the market in terms of service life. There is a 3 times improvement.
  • 10. How to calculate the volume matching ratio between finishing media and workpiece?
  • What is the most appropriate loading ratio of tumbler media to workpiece during primary finishing and polishing? This ratio depends on the finishing effect you want to achieve. Factors that need to be considered include the material, size, shape of the abrasive media, the material and weight of the workpiece.
    Below is a basic tumbler media : parts ratio guide, please refer to the table below to determine your usage:

    Tumbler Media to Workpiece Volume Ratio Typical Application
    0 : 1 no abrasive media, and the product is self-finishing and polishing, such as some decorative stones for handicrafts.
    1 : 1 Same proportion of tumbler media and products with very rough surface, such as forgings, castings, etc.
    2 : 1 Light finishing, allowing workpieces to collide with each other.
    3 : 1 Minimum ratio for copper, aluminum, zinc and other non-ferrous metal workpieces. The workpieces may collide with each other, so the ratio is suitable for finishing and polishing ferrous metals.
    4 : 1 Average efficiency ratio of non-ferrous metal workpieces. High efficiency ratio for ferrous metal parts.
    5 : 1 Suitable for finishing and polishing non-ferrous metal parts. Workpieces rarely collide with each other.
    6 : 1 Suitable for finishing and polishing of non-ferrous metal products. It is often used for pre-plating treatment of resin media and aluminum and zinc alloy workpieces.
    8 : 1 Suitable for finishing and polishing of non-ferrous metals or precision parts. Less surface roughness and smoothness.
    10:1~20:1 Better polishing quality. Suitable for irregular shapes or fragile workpieces.
    Max No collision between workpieces. One machine polishes one part or each workpiece needs to be separated.

  • 3. What kind of polishing effect can the hardware tumbler achieve?
  • In terms of polishing efficiency, this fully automatic hardware tumbler can process hundreds or thousands of kilograms of mechanical parts and hardware components at a time. It is a kind of automatic hardware polishing mechanical equipment that has been widely used.

    The effect of finishing depends on your needs for the product surface. To achieve the best surface finishing and polishing effect, most product polishing processes require three processes: rough finishing, fine finishing, and polishing.

    The first step is to finish it roughly. Use abrasive tumbler media with high cutting force to remove defects such as burrs, scale, flash, sharp edges on the product surface to form a smooth surface with low surface roughness.

    The second step is fine finishing. Use abrasive tumbler media with finer grit, some reaching micron powder size, to further perform micro-cutting on the product surface to achieve a smoother surface quality.

    The third step is polishing. Use high-density, non-cutting polishing tumbler media, such as high-aluminum porcelain media, high-density porcelain media, stainless steel media, or some bio-degradable tumbler media that can simulate the polishing effect of cloth wheels, such as walnut shell abrasive chip, corncob abrasive chip, polishing Wood particles, etc., combined with special brightening compound, can improve the gloss and brightness of the product surface and achieve a sparkling, close to mirror polishing effect.

  • 4. Are there any defects to hardware tumbler?
  • The main disadvantage of this automatic hardware tumbler is that it cannot polish a certain part of the product surface because it is an overall polishing process. For example, the oxide scale on the surface of a certain part of a product is relatively thick. If you want to focus on this part and spend more time to finish it, this will not work. The thickness of this part is ground, and other parts will also be ground to such a thickness.

    The surface quality is not as good as mirror polishing.

    Some inner holes and cross holes that are too deep and too thin, such as inner surfaces exceeding 50mm, cannot be finished and polished.

    Too long burrs and flash edges cannot be processed. For example, burrs and flash edges exceeding 2mm.

  • 5. How does the hardware tumbler finish and polish?
  • In order to solve the problems of low efficiency, low quality and high labor cost of manual finishing, ShineTec’s Hardware Tumbler is an automatic finishing and polishing machine. The main operating principle is to mix special tumbler abrasive media with product workpieces, appropriate amounts of water and finishing liquid in a certain proportion, and put them into the working barrel of the polishing machine, and use mechanical motion methods such as vibration, centrifugal high-speed rotation, tumbling rotation, etc. to make the ceramic tumbler media and workpiece tumble and rotate together in the barrel, and use the cutting force of the abrasive surface to finish the burrs on the surface of the workpiece.

    There are four main types of deburring and polishing machines. Each movement mode has its own advantages and disadvantages, and is suitable for different finishing and polishing needs. Vibratory finishing and polishing is the most common process method. If you need to process large quantities every day, such as hundreds of kilograms of product workpieces, then choose a vibrating polishing machine. If you need to process some small precision parts and components, the quantity is within tens of kilograms, Precision parts finishing and polishing machine is the best choice, then the centrifugal barrel finishing process is the most suitable method. If you are looking for the fastest polishing process, then centrifugal disc finishing is the fastest polishing method. If you want to find the cheapest, lowest cost finishing and polishing process, go for the tumbling barrel finishing method.

  • 6. What types of ShineTec’s hardware tumbler are there?
  • According to different operating modes, automatic hardware tumbler are divided into the following four types:

    6.1 Vibratory (vibrating) finishing and deburring polishing machine. It is a general-purpose finisher. The spiral vibration method is used to drive the tumbler media and the workpiece to move together to achieve the deburring, descaling, deflashing, derusting, finishing and polishing effect.

    6.2 Centrifugal barrel finisher. It is suitable for rapid deburring of precision parts. It is similar to the operation of a Ferris wheel. The motor drives the large centrifugal disk to rotate, allowing the four barrels on the disk to rotate at high speed, driving the tumbler media and the workpiece to move together to achieve the finishing and polishing effect.

    6.3 Centrifugal disc finisher. It is the fastest deburring equipment. The chassis drives the barrel to rotate at high speed on the horizontal plane. The tumbler media and workpiece also tumble and rotate in the barrel to achieve the finishing and polishing effect.

    6.4 Tumbling barrel finisher. It is the simplest structure and the lowest cost deburring method. The barrel rolls around the central axis, and the tumbler media in the barrel rolls together with the workpiece to achieve the finishing, polishing effect.

  • 7. How much does a hardware tumbler cost?
  • The price of the machine ranges from several thousand to tens of thousands. The price of tumbler media generally costs around a few thousand dollars for an initial order of several hundred kilograms. Such an automatic deburring and polishing solution can be said to be quite economical.
    However, the economic benefits or benefits brought by using the deburring and polishing machine are very high. If your products still use manual finishing and polishing, we can conduct a calculation of the processing cost to see how much our workpiece deburring and polishing machine can save you.

  • 8. What kind of abrasive media do hardware tumbler use?
  • Because our hardware tumbler can be used to handle a variety of surface treatment process requirements, the abrasive media provided are divided into three types: rough finishing, fine finishing and polishing:

    8.1 Tumbler media for rough finishing, mainly include tumbling deburring media, Resin (plastic) deburring media , divided into heavy cutting force, medium cutting force and light cutting force.

  • 11. What are the differences between different types of hardware tumblers?
  • As a small mass finishing machine, hardware tumbler are divided into the following four types according to different operating methods:

    11.1 Vibratory deburring finisher. It is a general-purpose grinding and deburring machine. The spiral vibration method is used to drive the abrasive media and the workpiece to move together to achieve the grinding, polishing and deburring effect.

    11.2 Centrifugal barrel deburring finisher. It is suitable for surface polishing of precision parts and components. It is similar to the operation of a Ferris wheel. The motor drives the large centrifugal disk to rotate, allowing the four barrels on the disk to rotate at high speed, driving the abrasive media and the workpiece to move together to achieve the grinding, polishing and deburring effect.

    11.3 Centrifugal disc deburring finisher. It is the fastest deburring equipment. The chassis drives the barrel to rotate at high speed on the horizontal plane. The tumbler media and workpiece also tumble and rotate in the barrel to achieve the grinding and polishing deburring effect.

    11.4 Barrel deburring finisher. It is the simplest structure and the lowest cost finishing and deburring method. The barrel rolls around the central axis, and the tumbling media in the barrel rolls together with the workpiece to achieve the grinding, polishing and deburring effect.

    11.5 Processing capability. We compare according to the largest models in their respective categories. The vibratory finishing machine can process tons of products at a time. The largest tumbling barrel finishing machine can also achieve such processing capabilities. The centrifugal disc finishing machine can reach 1-200 kg, the centrifugal barrel finishing machine can handle about 2-300 kg. Taking into account the processing time required for a complete batch, the processing capacity can be arranged in the following order: vibratory finisher >tumbling barrel finisher > centrifuge barrel finisher > centrifugal disc finisher.

    11.6 Machine noise. Vibratory finisher > Centrifugal disc finisher > Centrifugal barrel finisher > Tumbling barrel finisher.

    11.7 Finishing time. Centrifugal disc finisher > Centrifugal barrel finisher > Vibratory finisher> Tumbling barrel finisher.

    11.8 Finishing costs. Centrifugal disc finisher > Centrifugal barrel finisher > Vibratory finisher > Tumbling barrel finisher.

    11.9 Cutting force. Centrifugal disc finisher > Centrifugal barrel finisher > Tumbling barrel finisher > Vibratory finisher.

  • 12. What kind of daily maintenance can extend the service life of the hardware tumbler?
  • 12.1 Before each start-up, should the overall appearance of the machine be checked for damage? Is the foot position stable? Is there any abnormal noise during operation?

    12.2 Depending on the model, do you regularly check whether the spring of the machine is broken? Are there any cracks in the casing? Does the tension of the transmission chain, synchronous belt, and sprocket match? Is the lining damaged? Is there any water leakage from the sealing cover?

    12.3 The motor needs to be lubricated every month. Are there any signs of aging and failure of the electrical components? Is the copper wire of the electric wire exposed?

    12.4 Operate within the rated load capacity of the machine and do not overload it. Generally, the material loading capacity of the entire machine should not exceed 70% of the total load capacity of the machine.

    If you are a hardware finishing job shop, your finishing and polishing equipment must be in working condition for a long time, so good maintenance habits can better extend the service life of your hardware tumbler and create more benefits for you.

  • 13. How to buy a hardware tumbler?
  • As a finishing and polishing machine manufacturer, we have a variety of mass finishing machines available. Before ordering, you need to send samples for process testing. If you are satisfied with the results, please refer to the following steps to confirm your ordering requirements:

    13.1 Power requirements. Our hardware tumbler requires 380V/3-phase/50Hz industrial power and is not suitable for civilian 220V/2-phase power. Special requests need to be confirmed in advance.

    13.2 Processing capability requirements. First estimate the quantity of your product that needs to be processed every day, your shift schedule, and confirm the machine model based on the process plan.

    13.3 Your product parts size. These workpieces within 300mm can all be processed, but the vibrating finishing machine is the most commonly finisher. For workpieces that are too long, a long rectangular tub finishing machine is needed. Some small-sized precision parts require a precision finishing machine. It is recommended to use a centrifugal barrel finishing machine. Workpieces within 100mm require rapid deburring and polishing, then the centrifugal disc finishing machine is the best choice, It is not afraid of deformation or bumping. For thin workpieces within 300mm in length, which are easy to adsorb each other, use a barrel tumbling finishing machine.

    13.4 Selection of tumbling media. According to the effect of the testing sample, select the appropriate abrasive material, cutting strength, shape, and size.

    13.5 Wear resistance of tumbling media. Different cutting strengths, shapes, and sizes determine the different wear resistance properties of abrasive media. Finishing media with heavy cutting force have smaller wear resistance than media with light cutting force due to the large grit size of corundum sand contained. The larger the product, the longer it will last and the more wear-resistant it will be. There are also different shapes with different wear resistance. For example, shapes such as spheres and cylinders are more durable than triangles and tri-star shapes.

    13.6 Finishing time. The finishing efficiency of each model is different. You should choose the appropriate model based on your production shift schedule, product output, and batch processing time requirements for deburring and polishing.

    13.7 The intensity of working. The bowl of the vibrating finishing machine is open, making it easy to load materials; the disc type is similar and easy to load and unload; the centrifugal barrel type has a smaller working barrel and a smaller opening, so it takes more time to load and unload. The opening of the tumbling barrel is also small, and the loading and unloading of materials is relatively slow; the overall labor intensity and loading and unloading time are stronger than the disc type, the tumbling barrel type, and the centrifugal barrel type.

  • 14. How to improve the polishing efficiency of hardware tumbler?
  • Some precautions during actual use can help improve the efficiency of the hardware tumbler.

    14.1 Reasonable ratio of abrasive media to workpiece. The reasonable ratio of the two when loading and feeding is the key factor affecting the finishing and polishing efficiency. The most commonly used ratio is 3:1 abrasive media to workpiece. Please refer to the table below to determine your usage:

    Media to workpiece volume ratio Typical application
    0 : 1 No tumbling media, self-finishing and polishing, such as some decorative stones for handicrafts.
    1 : 1 The same proportion of abrasive media and parts such as forgings, castings, etc., with very rough surfaces.
    2 : 1 Gentle finishing, allowing workpieces to collide with each other.
    3 : 1 Minimum ratio for finishing copper, aluminum, zinc and other non-ferrous metal workpieces. The workpieces may collide with each other, so the ratio is suitable for grinding and polishing ferrous metals.
    4 : 1 The ratio of non-ferrous metal workpieces with average efficiency. High polishing efficiency ratio for ferrous metal parts.
    5 : 1 More suitable for finishing non-ferrous metal parts. Workpieces rarely collide with each other.
    6 : 1 Suitable for finishing of non-ferrous metal products. Commonly used for pre-plating treatment with resin media and aluminum and zinc alloy workpieces.
    8 : 1 Suitable for finishing of non-ferrous metals or precision parts. Less surface roughness and smoothness.
    10:1~20:1 Better finishing quality. Suitable for irregular shapes or fragile workpieces.
    Maximizing No collision between workpieces. One machine polishes one part or each workpiece needs to be separated.


    14.2 Loading capacity. Too much or too little loading will affect the finishing efficiency of the machine. Please do not feed materials at 100% full load or less than 50%. Generally, the overall volume of the material after loading does not exceed 70% of the barrel volume, and the water surface does not exceed 80% of the barrel volume.

    14.3 Amount of finishing compound liquid. Too little dosage will definitely not play the role of the additive in accelerating grinding. Too much dosage will produce a large amount of foam, which will pollute the environment, and on the other hand, it will block the tumbling and rotating motion of the abrasive media and the workpiece, reducing the grinding efficiency.

    14.4 Suitable machine operating speed. This is a process that requires long-term experience accumulation. Polishing efficiency depends on the material and size of the tumbling media used, the amount of water and chemical compound added, and the running speed of the machine. Too little material input and high-speed machine operation speed will cause over-grinding of the product, affecting the overall size, accuracy or chamfering degree. Excessive material input and too low machine speed will cause insufficient movement of the workpiece inside the abrasive media, reduce cutting strength, and affect efficiency.

  • 15. How long does it take to polish the parts with a hardware tumbler?
  • There are three factors that determine the finishing time it takes to a hardware deburring tumbler:

    15.1 The material and surface condition of the workpiece. The length, thickness, and location of burrs, flash, and sharp edges will all affect the processing time. In addition, the harder the workpiece is, the longer it will take. On the contrary, the softer the workpiece will be, the shorter the time will be.

    15.2 The choicing of polishing machines. Generally speaking, compared by finishing speed, centrifugal disc finisher > centrifugal barrel finisher > vibratory finisher > tumbling barrel finisher.

    15.3 The capacity of the machine. The larger the capacity of the machine, the greater the friction process between the abrasive media and the workpiece, and the faster the desired effect can be achieved.

  • 16. Which hardware tumbler is the best?
  • In the surface treatment industry, there are various finishing equipment and polishing process methods. Such as manual polishing, robot polishing, chemical polishing, electrolytic polishing, abrasive flow polishing, magnetic polishing, sandblasting and shot blasting, plasma polishing and other processes. Each polishing method has its own characteristics and applicable fields, so no one polishing machine is the best. Only the equipment that is more suitable for your own product polishing needs is the best.

  • 2. What are the advantages of a parts deburring machine compared to manual deburring?
  • In an era of automation and intelligence, are you still looking for manual deburring methods? Let us recommend to you this large-volume, high-efficiency automatic deburring and polishing process. Its comparative advantages over manual deburring are as follows:

    2.1 Compared with manual deburring, the efficiency can be improved dozens of times. Using some large-scale deburring and polishing machines, hundreds or even thousands of kilograms of material can be fed at one time, and all can be completed within dozens of minutes or hours. This processing efficiency is incomparable to manual polishing.

    2.2 The surface effect after deburring is uniform and controllable. The quality of manual deburring and polishing depends on the personal skill level of the worker. Some products may have clean burrs, while others may still have some residue. The surface quality of each product is different. Sometimes it may also cause product damage, resulting in a relatively high scrap rate.

    2.3 The running costs of parts deburring machines are extremely low. The one-time purchase cost of the machine starts from a few thousand dollars, and it can generally be used for many years. The choice of ordinary abrasive media depends on the actual conditions of the product parts that need to be processed, and the price ranges from a few dollars per kilogram to more than ten dollars, buying a few hundred kilograms at a time can usually take several months. The amount of finishing liquid is very small and the cost is almost negligible.
    Ordinary models can feed dozens of kilograms of workpieces at a time, and the deburring time for a batch is generally 30-60 minutes. The direct cost of finishing and polishing when evenly distributed to each product is minimal.
    On the other hand, in terms of saving labor costs, the advantages of automatic parts deburring machines are even greater. As long as workers need to handle it when loading and unloading materials, the machine can be operated unattended, which greatly saves labor costs.

    2.4 In addition to the automatic deburring function, ShineTec’s parts deburring machine can also perform surface treatment technology of descaling, derusting, cleaning, chamfering, degreasing, decontaminating, brightening, burnishing, etc., powerful functions and wide applicability.

  • 3.Can you tell me how the parts deburring machine deburrs?
  • In order to solve the problems of low efficiency, low quality and high labor cost of manual deburring, ShineTec’s parts deburring machine is an automatic finishing and polishing machine. The main operating principle is to use a dedicated Tumbling Deburring Media are mixed with the product workpiece, an appropriate amount of water and chemical finishing liquid in a certain proportion, and put into the working barrel, mechanical movements such as vibrating, centrifugal high-speed rotation, disc rotation, and tumbling rolling rotation are used to rotate the abrasive media and the workpiece together in the barrel, and the cutting force of the abrasive surface is used to finish the burrs on the surface of the workpiece.

    There are four main product types of parts deburring machines. Each movement mode has its own advantages and disadvantages, and is suitable for different finishing, polishing and deburring needs. Vibratory deburring is the most common process method. If you need to process large quantities every day, such as product workpieces of hundreds of kilograms or more, then choose a vibrating deburring machine. If you need to process some small precision parts, the quantity is within tens of kilograms, the centrifugal barrel deburring process is the most suitable method. If you are looking for the fastest deburring process, then centrifugal disc deburring is the fastest polishing method. If you want to find the cheapest, lowest cost deburring process, go for the tumbling barrel deburring method.

  • 11. How to buy a parts deburring machine?
  • Before ordering, you need to send samples for process testing. If you are satisfied with the results, please refer to the following steps to confirm your ordering requirements:

    11.1 Power requirements. Our parts deburring machine requires 380V/3-phase/50Hz industrial power and is not suitable for civilian 220V/2-phase power. Special requests need to be confirmed in advance.

    11.2 Processing capability requirements. First estimate the quantity of your product that needs to be processed every day, your shift schedule, and confirm the machine model based on the process plan.

    11.3 Your product parts size. The workpiece within 300mm can be processed by all models, but the vibrating finisher is the most commonly used deburring equipment. For workpieces that are too long, a rectangular tub-shaped vibrating deburring machine is needed. Some small-sized precision parts require the use of a centrifugal barrel finisher. For workpieces within 100mm that need to be quickly deburred, a centrifugal disc finisher is the best choice. No afraid of deformation or bumping. Use a barrel tumbling finisher for thin workpieces within 300mm in length that are easy to adsorb to each other.

    11.3 Selection of deburring media. According to the effect of the sample, select the appropriate abrasive media, cutting strength, shape, and size.

    11.4 Wear resistance of tumbling media. Different cutting strength, shape, and size determine the different wear resistance properties of abrasive media when used. Tumbling media with heavy cutting force have smaller wear resistance than media with light cutting force due to the large grit size of corundum sand contained. The larger the product, the longer it will last and the more wear-resistant it will be. There are also different shapes with different wear resistance. For example, shapes such as spheres and cylinders are more durable than triangles and tri-star shapes.

    11.5 Finishing time. The deburring efficiency of each model is different. You should choose the appropriate model based on your production shift schedule, product output, and batch processing time requirements for finishing and polishing.

    11.6 The working intensity. The bowl of the vibrating deburring machine is open, making it easy to load materials; the centrifugal disc type is similar and easy to load and unload; the centrifugal barrel type has a smaller working barrel and a smaller opening, so it takes more time to load and unload. The opening of the tumbling barrel is also small, and the loading and unloading of materials is relatively slow; the overall labor intensity and loading and unloading time are stronger than the centrifugal disc/barrel type.

    If you want to buy a metal deburring machine, precision parts deburring machine, gear deburring machine, laser cutting deburring machine, plastic product deburring machine, ShineTec’s workpiece deburring and polishing machine should be able to meet your requirements.

  • 12. How to improve the finishing efficiency of parts deburring machine?
  • Some precautions during actual use can help improve the efficiency of the automatic deburring and polishing machine.

    12.1 Reasonable ratio of abrasive media to workpiece. The reasonable ratio of the two when loading and feeding is the key factor affecting the finishing and polishing efficiency. The most commonly used ratio is 3:1 abrasive to workpiece. Please refer to the table below to determine your usage:

    Abrasive media to workpiece volume ratio Typical application
    0 : 1 No tumbling media, self-finishing and polishing, such as some decorative stones for handicrafts.
    1 : 1 The same proportion of abrasive media and parts such as forgings, castings, etc., with very rough surfaces.
    2 : 1 Gentle finishing, allowing workpieces to collide with each other.
    3 : 1 Minimum ratio for finishing copper, aluminum, zinc and other non-ferrous metal workpieces. The workpieces may collide with each other, so the ratio is suitable for grinding and polishing ferrous metals.
    4 : 1 The ratio of non-ferrous metal workpieces with average efficiency. High polishing efficiency ratio for ferrous metal parts.
    5 : 1 More suitable for finishing non-ferrous metal parts. Workpieces rarely collide with each other.
    6 : 1 Suitable for finishing of non-ferrous metal products. Commonly used for pre-plating treatment with resin media and aluminum and zinc alloy workpieces.
    8 : 1 Suitable for finishing of non-ferrous metals or precision parts. Less surface roughness and smoothness.
    10:1~20:1 Better finishing quality. Suitable for irregular shapes or fragile workpieces.
    Maximizing No collision between workpieces. One machine polishes one part or each workpiece needs to be separated.


    12.2 Loading capacity. Too much or too little loading will affect the finishing efficiency of the machine. Please do not feed materials at 100% full load or less than 50%. Generally, the overall volume of the material after loading does not exceed 70% of the barrel volume, and the water surface does not exceed 80% of the barrel volume.

    12.3 Amount of finishing compound liquid. Too little dosage will definitely not play the role of the additive in accelerating grinding. Too much dosage will produce a large amount of foam, which will pollute the environment, and on the other hand, it will block the tumbling and rotating motion of the abrasive media and the workpiece, reducing the grinding efficiency.

    12.4 Suitable machine operating speed. This is a process that requires long-term experience accumulation. Polishing efficiency depends on the material and size of the tumbling media used, the amount of water and chemical compound added, and the running speed of the machine. Too little material input and high-speed machine operation speed will cause over-grinding of the product, affecting the overall size, accuracy or chamfering degree. Excessive material input and too low machine speed will cause insufficient movement of the workpiece inside the abrasive media, reduce cutting strength, and affect efficiency.

  • 13.How long does it take to deburr a workpiece with a parts deburring machine?
  • There are three factors that determine the finishing time it takes to a hardware deburring tumbler:

    13.1 The material and surface condition of the workpiece. The length, thickness, and location of burrs, flash, and sharp edges will all affect the processing time. In addition, the harder the workpiece is, the longer it will take. On the contrary, the softer the workpiece will be, the shorter the time will be.

    13.2 The choicing of polishing machines. Generally speaking, compared by finishing speed, centrifugal disc finisher > centrifugal barrel finisher > vibratory finisher > tumbling barrel finisher.

    13.3 The capacity of the machine. The larger the capacity of the machine, the greater the friction process between the abrasive media and the workpiece, and the faster the desired effect can be achieved.

  • 14. Is the parts deburring machine safe?
  • Compared with polishing processes such as angle grinders, belt sanders, or chemical finishing used for manual polishing, the parts deburring machine is the most secure.
    As long as you follow regular daily maintenance and pay more attention to whether the power cord is broken or the copper wire is exposed, the machine will be safe for daily use.
    Wastewater will be produced during the deburring process, which can be recycled and will not affect the environment. Therefore, there are no safety issues in environmental protection.

  • 3.Can you tell me how the deburring tumbler works?
  • In order to solve the problems of low efficiency, low quality and high labor cost of manual deburring, ShineTec’s deburring tumbler is an automatic deburring and polishing machine. The main operating principle is to combine special tumbler media with product workpieces, appropriate amounts of water and finishing compound. Mix them together in a certain proportion and put them into the working barrel of the deburring machine. Vibrating, centrifugal barrel high-speed rotating, centrifugal disc rotating, tumbling barrel rolling and other mechanical movements are used to tumble and rotate the finishing media and the workpiece together in the barrel, using the cutting force of the abrasive media surface, polish the burrs on the surface of the workpiece.
    Each movement method has its own advantages and disadvantages, and is suitable for different finishing and deburring needs. Vibratory deburring is the most common process method. If you need to process large quantities every day, such as workpieces of hundreds of kilograms or more, then choose a vibrating deburring machine. If you need to process some small precision parts, the quantity is within tens of kilograms, the centrifugal barrel deburring process is the most suitable method. If you are looking for the fastest deburring process, then centrifugal disc deburring is the fastest polishing method. If you want to find the cheapest, lowest cost deburring process, go for the barrel tumbling deburring method.

  • 4. What are the benefits with a deburring tumbler?
  • The main benefit is that this is a high-volume, high-efficiency automatic deburring process. details as follows:

    4.1 Compared with manual deburring, the efficiency can be improved dozens of times. Using some large-scale deburring machines, hundreds or even thousands of kilograms of material can be fed at one time, and all can be completed within dozens of minutes or hours. Such processing efficiency cannot be compared with manual deburring.

    4.2 The surface effect after deburring is uniform and controllable. The quality of manual deburring and polishing depends on the personal skill level of the worker. Some products may have clean burrs, while others may still have some residue. The surface quality of each product is different. Sometimes it may also cause product damage, resulting in a relatively high scrap rate.

    4.3 The running costs of deburring tumblers are extremely low. The one-time purchase cost of the machine starts from a few thousand dollars, and it can generally be used for many years. The choice of ordinary tumbler deburring media depends on the actual conditions of the product parts that need to be processed, and the price ranges from a few dollars per kilogram to more than ten dollars. Buying a few hundred kilograms at a time can usually take several months. The amount of polishing fluid is very small and the cost is almost negligible.
    Ordinary models can feed dozens of kilograms of workpieces at a time, and the deburring time for a batch is generally 30-60 minutes. The direct cost of finishing and polishing when evenly distributed to each product is minimal.
    On the other hand, the advantages of automatic deburring tumbler are even greater in terms of saving labor costs. As long as workers need to handle it when loading and unloading materials, the machine can be operated unattended, which greatly saves labor costs.

    4.4 In addition to the automatic deburring function, ShineTec’s deburring tumbler can also perform surface treatment processes such as descaling, derusting, deflashing, smoothing, cleaning, chamfering, degreasing, decontaminating, and improvement of surface brightness. It features powerful functions and wide applicability. If you don’t know how to quickly deburr your product, we recommend you learn more about our fully automatic deburring tumbler.
  • 5. What types of deburring tumbler do ShineTec have?
  • According to different operating modes, our deburring tumblers are divided into the following four types:

    5.1 Vibratory Deburring Machine. It is a general-purpose deburring machine. The spiral vibration method is used to drive the deburring media and the workpiece to move together to achieve the vibration deburring effect.

    5.2 Centrifugal Barrel Deburring Machine. It is suitable for rapid deburring of precision parts and components. It is similar to the operation of a Ferris wheel. The motor drives the large centrifugal disk to rotate, allowing the four barrels on the disk to rotate at high speed, driving the deburring media and the workpiece to move together to achieve the centrifugal deburring effect.

    5.3 Centrifugal Disc Deburring Machine. It is the fastest deburring equipment. The chassis drives the barrel to rotate at high speed on the horizontal plane. The deburring media and workpiece also tumble and rotate in the barrel to achieve the disc deburring effect.

    5.4 Tumbling Barrel Deburring Machine. It is the simplest structure and the lowest cost deburring method. The barrel rolls around the central axis, and the deburring media in the barrel rolls together with the workpiece to achieve the tumbling deburring effect.

  • 6. What does dry and wet deburring mean?
  • Dry finishing is a deburring and polishing method that only adds finishing media, workpieces, polishing paste or polishing powder when the machine is running, and does not add water.
    Wet finishing is a deburring and polishing method that requires adding an appropriate amount of chemical liquid and water to the finishing media and workpiece when the machine is running.
    Wet finishing is the most widely used finishing and polishing process. For most common materials and general-purpose products, wet deburring is the most suitable method. With the assistance of water and liquid finishing compound, it can speed up the deburring process, reduce bumps, lower the machine operating temperature, and avoid dust producing, extending the service life of the machine.
    Dry finishing is mainly used in the polishing process of some products that cannot come into contact with water, such as the deburring process of some easily corroded metal products, wooden handicrafts, precision parts, and the drying process of products after wet finishing.

  • Let’s compare the differences between different types of automatic deburring tumblers from the following aspects:

    10.1 Processing capability. We compare according to the largest models in their respective categories. The vibrating deburring machine can process tons of products at a time. The largest barrel deburring machine can also achieve such processing capabilities. The centrifugal disc deburring machine can reach 1-200 kg, the centrifugal barrel deburring machine can handle about 2-300 kg. Taking into account the processing time required for a complete batch, the processing capacity can be arranged in the following order: vibratory finisher > tumbling barrel finisher > centrifugal barrel finisher > centrifugal disc finisher.

    10.2 Machine noise. vibratory tumbler > centrifugal disc tumbler > centrifugal barrel tumbler > tumbling barrel tumbler.

    10.3 Deburring time. centrifugal disc tumbler > centrifugal barrel tumbler > vibratory tumbler > tumbling barrel tumbler.

    10.4 Deburring cost. centrifugal disc tumbler > centrifugal barrel tumbler > vibratory tumbler > tumbling barrel tumbler.

    10.5 Cutting force. centrifugal disc tumbler > centrifugal barrel tumbler > tumbling barrel tumbler > vibratory tumbler.

  • 11.What kind of daily maintenance can extend the service life of the deburring tumbler?
  • 11.1 Do not overload the machine. Each automatic deburring tumbler has a rated usage capacity, so the machine cannot be overloaded in order to improve production efficiency. Generally, the material loading capacity of the entire machine should not exceed 70% of the total load capacity of the machine.

    11.2 Maintain regular maintenance. The specific work content involves the lubrication of the motor, inspection of the PU lining, inspection of the integrity of mechanical components, inspection of operating temperature, etc.

    11.3 Inspection of electrical systems. Check whether the components in the electrical control box are aging, and whether the power cord is broken or the copper wire is exposed.

  • 12.How to buy a deburring tumbler?
  • We are a manufacturer of deburring tumbler. Before ordering, you need to send samples for process testing. If you are satisfied with the results, please refer to the following steps to confirm your ordering requirements:

    12.1 Power requirements. Our parts deburring machine requires 380V/3-phase/50Hz industrial power and is not suitable for civilian 220V/2-phase power. Special requests need to be confirmed in advance.

    12.2 Processing capability requirements. First estimate the quantity of your product that needs to be processed every day, your shift schedule, and confirm the machine model based on the process plan.

    12.3 Your product parts size. The workpiece within 300mm can be processed by all models, but the vibrating finisher is the most commonly used deburring equipment. For workpieces that are too long, a rectangular tub deburring machine is needed. Some small-sized precision parts require the use of a centrifugal barrel finisher. For workpieces within 100mm that need to be quickly deburred, a centrifugal disc finisher is the best choice. No afraid of deformation or bumping. Use a barrel tumbling finisher for thin workpieces within 300mm in length that are easy to adsorb to each other.

    12.3 Selection of deburring media. According to the effect of the sample, select the appropriate abrasive media, cutting strength, shape, and size.

    12.4 Durability of tumbling media. Different cutting strength, shape, and size determine the different wear resistance properties of abrasive media when used. Tumbling media with heavy cutting force have smaller wear resistance than media with light cutting force due to the large grit size of corundum sand contained. The larger the product, the longer it will last and the more wear-resistant it will be. There are also different shapes with different wear resistance. For example, shapes such as spheres and cylinders are more durable than triangles and tri-star shapes.

    12.5 Finishing time. The deburring efficiency of each model is different. You should choose the appropriate model based on your production shift schedule, product output, and batch processing time requirements for finishing and polishing.

    12.6 The working intensity. The bowl of the vibrating deburring machine is open, making it easy to load materials; the centrifugal disc type is similar and easy to load and unload; the centrifugal barrel type has a smaller working barrel and a smaller opening, so it takes more time to load and unload. The opening of the tumbling barrel is also small, and the loading and unloading of materials is relatively slow; the overall labor intensity and loading and unloading time are stronger than the centrifugal disc/barrel type.

  • 13.What tips can improve the deburring efficiency of deburring tumbler?
  • Some precautions during actual use can help improve the efficiency of the automatic deburring and polishing machine.

    13.1 Reasonable ratio of abrasive media to workpiece. The reasonable ratio of the two when loading and feeding is the key factor affecting the finishing and polishing efficiency. The most commonly used ratio is 3:1 abrasive to workpiece. Please refer to the table below to determine your usage:

    Abrasive media to workpiece volume ratio Typical application
    0 : 1 No tumbling media, self-finishing and polishing, such as some decorative stones for handicrafts.
    1 : 1 The same proportion of abrasive media and parts such as forgings, castings, etc., with very rough surfaces.
    2 : 1 Gentle finishing, allowing workpieces to collide with each other.
    3 : 1 Minimum ratio for finishing copper, aluminum, zinc and other non-ferrous metal workpieces. The workpieces may collide with each other, so the ratio is suitable for grinding and polishing ferrous metals.
    4 : 1 The ratio of non-ferrous metal workpieces with average efficiency. High polishing efficiency ratio for ferrous metal parts.
    5 : 1 More suitable for finishing non-ferrous metal parts. Workpieces rarely collide with each other.
    6 : 1 Suitable for finishing of non-ferrous metal products. Commonly used for pre-plating treatment with resin media and aluminum and zinc alloy workpieces.
    8 : 1 Suitable for finishing of non-ferrous metals or precision parts. Less surface roughness and smoothness.
    10:1~20:1 Better finishing quality. Suitable for irregular shapes or fragile workpieces.
    Maximizing No collision between workpieces. One machine polishes one part or each workpiece needs to be separated.


    13.2 Loading capacity. Too much or too little loading will affect the finishing efficiency of the machine. Please do not feed materials at 100% full load or less than 50%. Generally, the overall volume of the material after loading does not exceed 70% of the barrel volume, and the water surface does not exceed 80% of the barrel volume.

    13.3 Amount of finishing compound liquid. Too little dosage will definitely not play the role of the additive in accelerating grinding. Too much dosage will produce a large amount of foam, which will pollute the environment, and on the other hand, it will block the tumbling and rotating motion of the abrasive media and the workpiece, reducing the grinding efficiency.

    13.4 Suitable machine operating speed. This is a process that requires long-term experience accumulation. Polishing efficiency depends on the material and size of the tumbling media used, the amount of water and chemical finishing liquid added, and the running speed of the machine. Too little material input and high-speed machine operation speed will cause over-grinding of the product, affecting the overall size, accuracy or chamfering degree. Excessive material input and too low machine speed will cause insufficient movement of the workpiece inside the abrasive media, reduce cutting strength, and affect efficiency.

  • 14. How long does it take for a deburring tumbler to work?
  • It depends on the specifics of your product. Generally speaking, soft metals such as aluminum alloys and zinc alloys can achieve a satisfactory effect in less than an hour, while hard product workpieces such as stainless steel, titanium alloys, and cemented carbide may require Requires more than 2 hours of deburring time.
    In addition, the size of the machine used also affects the processing time. The bigger the machine, the less time it takes to grind.
