Note: There is a plastic protective film on the back.

5. Additional instructions
  • 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.

6. Final summary
  • In this case, we demonstrate a process for surface chamfering and deburring of stainless steel laser-cut metal sheet parts using resin finishing media and corn cob drying media.

What is hardware tumbler?

About Hardware Tumbler

  • 1．What is hardware tumbler?
  • ShineTec’s hardware tumbler is a kind of automatic hardware finishing machinery and equipment, specially used for machining, precision molds, auto parts, aerospace, medical equipment, mechanical parts, plastic products, 3C digital, metal casting, electronics High-efficiency high-volume deburring, deflashing, descaling, smoothing, polishing of hardware parts produced in devices, hardware parts, kitchen supplies, 3D printing, textile workpieces, powder metallurgy, electrical components, minting, jewelry, instrumentation, handicraft accessories and other industries.
    ShineTec's hardware finishing and polishing machine
  • 2. Why use a hardware tumbler for finishing and polishing?
  • I believe that as a manufacturing owner, your products will no longer want to use manual polishing methods. If your products are still polished manually, we recommend that you try ShineTec’s automatic hardware finishing machine. The specific advantages 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 polishing is uniform and controllable. The quality of hand polishing depends on the personal skill proficiency of the worker. Some products may have burrs finished 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.

    2.3 The operating costs of a automatic hardware tumbler 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 polishing materials depends on the actual situation 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 compound is very small and the cost is almost negligible.
    Ordinary models 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, the advantages of automated hardware 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.

    2.4 In addition to the automatic deburring function, ShineTec’s hardware tumbler can also perform surface polishing processes such as descaling, derusting, deflashing, cleaning, chamfering, degreasing, decontaminating, and improvement of surface brightness. Craftsmanship, powerful functions and wide applicability.

  • 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.

    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.

  • 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.

  • According to different operating modes, parts deburring machines are divided into the following four types:

    4.1 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.

    4.2 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.

    4.3 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.

    4.4 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.

  • 5. How much does a parts deburring machine cost?
  • The price of the machine ranges from several thousand to tens of thousands. The price of deburring 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 brought by using a automatic parts deburring 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.

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

    6.1 Ceramic tumbling media for rough finishing, mainly include Ceramic Deburring Media, Resin Finishing Media , divided into heavy cutting force, medium cutting force and light cutting force.

    6.2 Fine finishing media, include white corundum finishing media, chrome corundum finishing media, 3P finishing 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.

    6.3 Tumbling polishing media include high alumina porcelain polishing media, high-density porcelain polishing media (high-alumina porcelain media with an alumina content of more than 95%), stainless steel polishing media, Walnut shell polishing media, corn cob polishing media and so on. The main purpose is to improve the gloss and brightness of the workpiece surface.

  • 7．What kind of parts deburring machine is a good and qualified machine?
  • To measure whether a parts deburring machine is qualified or not, it mainly depends on the quality of the raw materials used and the quality control during the production and manufacturing process.

    7.1 Quality assurance of raw materials. Because the PU lining in the working barrel of the machine is a wearing part and needs to be replaced regularly, the wear resistance of the PU lining is a key quality indicator. The raw materials of our PU come from American Dow Chemical products, and the quality can be guaranteed.

    7.2 Reliable motor quality. The motor used in the parts deburring machine is a key component related to product quality.

  • 10. What kind of daily maintenance can extend the service life of the parts deburring machine?
  • As a manufacturer of automatic deburring machines, we recommend the following daily maintenance measures:

    10.1 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?

    10.2 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 gel damaged? Is there any water leakage from the sealing cover?

    10.3 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?

    10.4 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.

  • 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.
