5. Additional instructions
  • 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.

Laser cutting workpieces made of plastic or acrylic are suitable for polishing with high density porcelain tumbling media. This tumbling media does not contain abrasive sand, has no cutting force, and will not scratch the surface of the product.

  • 1. What are laser cut parts?
  • Laser cutting parts are workpieces produced using laser cutting processing technology. It is used in spare parts for products with high precision requirements in various industrial fields.
  • 2. Why do laser cut parts need to be deburred?
  • Laser-cut parts produced during processing must undergo surface treatment processes such as deburring and polishing.
    The benefits of applying this finishing process are as follows:

    2.1 Remove oxide layer.
    Laser cutting uses gases such as oxygen or carbon dioxide as assistance. These gases will form an oxide layer on the surface of the product during high-temperature cutting. It may corrode or rust the parts, so you must polish these cutting parts to remove the oxide layer.

    2.2 Improve product appearance quality.
    The appearance of a product affects its quality. If you are a practitioner of machined parts, using the deburring and finishing process can provide a beautiful and uniform appearance to the workpiece.

    2.3 Repair product surface quality.
    The laser cutting process may cause certain appearance defects to the workpiece, such as silk lines, cracks, pitting, etc. Through finishing and polishing, these defects can be repaired, thereby improving product yield and reducing production costs.

    2.4 Chamfer processing.
    Laser cutting will produce sharp edges or corners, which may cause harm to users during use.
    After chamfering, sharp edges can be removed and sharp corners can be smoothed and rounded. It can also reduce product stress, which affects product durability and quality stability.

    2.5 Produces a special matte effect.
    Some products may require a matte finish. This demand can be met by using appropriate tumbling abrasive media and correct finishing and polishing processes.

    2.6 Improve security.
    Flashes, sharp edges, and sharp corners on the surface of the workpiece may cause harm to the user. Therefore, it is necessary to use a deburring and finishing machine for polishing in the subsequent process to improve the surface quality of the product.
  • 3. Can you explain the method of deburring from laser cutting workpieces?
  • Currently, many laser-cut parts are still polished manually. For example, traditional deburring methods such as sandpaper, power tools with grinding heads, belt sanders, and grinding wheels are used.
    These backward polishing methods are inefficient, not environmentally friendly, and also bring many safety hazards.
    Some new deburring processes include ultrasonic, thermal energy, electrochemical, sandblasting, shot blasting and other methods. Each has its own characteristics and limitations.
    The tumbling finishing and polishing process we currently provide is a low-cost, high-volume, and high-efficiency mechanized deburring and polishing method, which is especially suitable for some special-shaped laser cutting parts with complex cavities.
  • 4. What kind of equipment is the laser cutting workpiece deburring machine?
  • Laser cutting parts polishing machine is a machine used to deburr, descale, chamfer, clean, degrease, and polish and brighten laser cut products. Using the right tumbling abrasive media and choosing the right machine type will make your process more efficient. At the same time, it can also reduce labor costs, reduce labor intensity, and improve production efficiency.
  • 5. What are the advantages of laser cutting parts finishing and polishing machines?
  • The benefits of laser cutting parts deburring and polishing machines are as follows:

    5.1 Lower processing costs. Manual deburring requires high labor costs, more tools and abrasive material losses. Our finishing and polishing machine for laser cutting is a one-time investment. Later, you only need to purchase some tumbling media, chemical compound liquid regularly. Only very little manual participation is required during the processing, so labor costs will be greatly reduced.

    5.2 Save time. It is obvious that machine deburring and polishing can greatly save operating time compared to manual polishing. Your productivity can be greatly improved.

    5.3 Non-destructive surface treatment. Use suitable matching tumbling finishing media and choose the correct mass finishing equipment. After completing the polishing processes such as deburring and descaling, your product workpiece will not change in shape, position and size. It is a lossless process. If it is polished by hand, due to the different handling strength of each workpiece, it may have an impact on the size of the product, and each one is not uniform.

    5.4 Get the best surface quality. The quality of product appearance determines the quality of the product. Manual polishing cannot achieve a consistently stable product surface quality. But a polishing machine can give you a consistent look. Finishing time and surface roughness level can be controlled, helping you to stand out in the fierce market competition.

    5.5 Save labor. At present, the labor cost of product polishing process accounts for a large proportion of the overall product cost. ShineTec’s finishing and polishing machine allows a single worker to perform multiple batches of mechanized deburring, descaling and polishing, which will save a lot of labor costs and greatly reduce labor intensity.

    5.6 High-volume polishing. Our finishing and polishing solutions are characterized by high-volume, high-efficiency, mechanized automatic finishing. Laser cutting parts of different shapes and sizes can be processed in the same polishing machine. If combined with automated assembly lines, your production efficiency and product quality can be greatly improved.

    5.7 Extremely low maintenance costs. The daily maintenance cost of the machine and the loss of tumbling media are the most important factors for business owners to consider. ShineTec’s finishing and polishing machines have almost no maintenance costs. In addition to regularly adding a little lubricant to the motor, there are no other special tools that need to be purchased.

    5.8 No specially trained operators are required. Manual finishing and polishing requires special training for operators first. This is a high labor cost and an uncontrollable link in the production process. The mass finishing machines we provide are very simple to operate. Workers only need to load and unload materials. The polishing process of the machine does not require manual participation.

    5.9 Safe production environment. Laser-cut parts may have sharp corners, burrs or flash edges, which may cause harm to front-line workers. Debris generated during manual polishing may also enter people’s eyes or cause skin allergic reactions. Using finishing and polishing machines can avoid these phenomena. Provide production workers with a safe and reliable production working environment.

    5.10 Improve the adhesion of electroplating, paint and coatings. Some laser-cut parts may require electroplating, painting or coating treatment in the final stage. If polished by hand, the appearance of the product will be inconsistent, resulting in unstable surface quality of the finished product. After using our tumbling finishing and polishing, there will be a uniform surface quality before subsequent surface treatment, and a reliable and stable product quality will be obtained later.
  • 6. What types of laser cutting parts deburring machines does ShineTec have?
  • ShineTec provides different tumbling finishing and polishing machines that can be used to polish laser cut parts. They are vibratory/vibrating deburring and finishing machines, centrifugal barrel finishing machines, centrifugal disc finishing machines, and barrel tumbling finishing machines. Depending on the material, shape, specification and size of the workpiece, we can select the correct machine model and matching ceramic deburring media, porcelain polishing media and other tumbling media to meet your process requirements.

    6.1 Vibratory Finishing Machine. Vibration type, also called vibrating finishing and polishing machine, is the most commonly used equipment for deburring and polishing laser cutting parts. It is characterized by strong applicability, large processing capacity, easy operation, convenient loading and unloading, and controllable process. Generally, small and medium-sized special-shaped workpieces can be processed. The disadvantage is that it is not easy to penetrate deep into the cavity.

    6.2 Centrifugal Barrel Finishing Machine。 The centrifugal barrel finishing type, is a device suitable for finishing and polishing some small-sized laser cutting workpieces. It is characterized by strong cutting force, short processing time, and the ability to penetrate deep into the inner holes and gaps of the workpiece. The disadvantage is that the processing capacity is not large at one time, and loading and unloading is time-consuming.

    6.3 Centrfugal Disc Finishing Machine。 The centrifugal disc finishing machine is suitable for processing some laser cutting workpiece products with large burrs. It is characterized by the strongest cutting force, short processing time and easy loading and unloading. Generally speaking, compared with vibratory polishing machines, the finishing and polishing efficiency can be increased by about 30 times. The disadvantage is that it is not suitable for some thin laser cutting parts and is easy to deform or get stuck in the gaps of the machine chassis.

    6.4 Tumbling Barrel Finishing Machine. Also called rotary barrel polishing machine. It is suitable for parts with high surface polishing brightness and gloss requirements. It is characterized by slow work and careful work, combined with special abrasive media, such as walnut shells, corn cobs, wood, bamboo chips and other plant abrasives, and polishing paste, which can bring a mirror-like shiny surface effect. The disadvantage is that the processing time is slow and the efficiency is low. Some parts may need to be processed for several days at a time. It is also not suitable for some easily deformed laser cutting workpieces.
  • 7. What deburring abrasive media are used in laser cutting parts deburring machines?
  • The tumbling media used for finishing and polishing laser cutting parts are also called mass finishing media. ShineTec offers a wide range of abrasive media. The factors that affect the quality of abrasives mainly include cutting force, wear resistance, specific gravity density, hardness, appearance size, color and other indicators. High-quality raw materials and scientific production process control bring high-quality abrasive media. The main types are as follows:

    7.1 Brown Corundum Ceramic Deburring Media. Brown corundum ceramic media is a commonly used abrasive material used for deburring, descaling, deflashing and finishing of laser cutting parts. Suitable for hard metal parts. The deburring ceramic media provided by ShineTec are available in triangular, cylindrical, spherical, conical, three-star, oval, pyramid, tetrahedral and other shapes. Each shape has different specifications and sizes. Each abrasive media also has different cutting force levels. Heavy cutting force deburring media are used for workpieces that require a lot of finishing and cutting force, and light cutting force deburring media are used for some product workpieces that require a lot of smoothness.

    7.2 High Alumina Porcelain Media. High-alumina porcelain media do not contain brown corundum sand with strong cutting force. Therefore, this tumbling polishing media has no cutting force and cannot be used for deburring, descaling and other processing. Because of the high alumina content, the polishing abrasive media formed after final sintering has a large specific gravity, dense internal structure, and strong hardness. It is suitable for polishing processes that improve the surface brightness of laser cutting workpieces. The greater the specific density, the higher the surface brightness of the treated product. The appearance color is porcelain white, and the shapes are generally spherical, triangular, cylindrical, oval, etc.

    7.3 Resin Media。 Tumbling resin media are also called Plastic Media, Polyester Media. Because they have a moderately elastic surface, they are suitable for polishing and polishing laser cutting parts produced from soft metals such as aluminum alloys. Resin grinding stone is an abrasive material made of resin mixed with corundum sand powder through a curing reaction. It is also suitable for deburring and polishing workpieces made of materials such as copper and plastic. ShineTec can provide resin abrasives in conical, pyramid, triangular, three-star, bullet and other shapes. Brown corundum sand containing different mesh numbers can bring different cutting forces, and can also be divided into heavy cutting, medium cutting, and light cutting grades.

    7.4 Stainless Steel Media。 This polishing media is made of stainless steel. Because it has no cutting force and a density of up to 7.8 g/cm3, it is also used to polish the surface brightness of laser-cut parts. The specific gravity is more than three times higher than that of high-alumina porcelain polishing media, and the surface brightness obtained after polishing is also far superior to that of high-alumina porcelain polishing media. The shapes include ball, ballcone (ufo), and pin shapes, which are suitable for brightening metal workpieces.

    7.5 Mirror Polishing Media. It is mainly produced by processing walnut shells, corn cobs, cork pellets, bamboo chips, etc. In addition to their finishing and polishing functions, walnut shells and corncobs are also used to dry cleaned workpieces in a vibration dryer because of their strong water absorption. Vegetable tumbling media are mainly used to polish the surface brightness of laser cutting parts. When used in conjunction with a barrel tumbling polishing machine, a mirror-like bright effect can be achieved.
  • 8. Which products’ laser-cut parts can be used with this tumbling finishing deburring and polishing machine?

Finishing process method for deburring, deflashing, trimming from plastic rubber silicone and nylon product parts

How to remove burrs,flash and finish plastic, rubber, silicone and nylon product parts?

During the injection molding process of rubber, plastic, silicone and nylon products, due to mold, process or raw material reasons, a large number of burrs and flash often occur on the edge of the product or in the inner hole. The existence of this burr phenomenon will have a negative impact on the surface quality of the product. The commonly used and simple method of deburring and trimming is to use a scraper for manual processing. Of course, this is only suitable for a small number of products. If large quantities of automated mechanical processing are required, since rubber, plastic, silicone, and nylon products are soft and tough, Conventional vibration/barrel finishing, electrolysis, plasma, and magnetic processes cannot achieve satisfactory results. Today we will share a case of how to deburr, deflash from rubber shin guard products to achieve high-efficiency trimming in large quantities. This finishing process is also suitable for trimming requirements of other plastic, polyester, silicone, nylon, aluminum alloy, zinc alloy and other product parts with soft, light and hard-to-break burrs such as mobile phone cases, watch bands, O-rings and other plastics.

5. Additional instructions
  • Due to process limitations, rubber, aluminum alloy, zinc alloy and other products made by injection molding, casting and other processes often have a long layer of burrs around them after molding. This kind of burr is very thin, easy to bend, and has a certain degree of toughness, so simple mechanical and physical removal methods are not effective. Nowadays, a special deburring and trimming machine for rubber and plastic products is used to place the workpieces in batches into a special barrel and roll them. During the processing, liquid nitrogen is added to reduce the surface of the workpieces to more than 100 degrees below zero in a short time, making the edges of the workpieces The burrs and flash will become brittle and broken, but the body of the workpiece will not be affected. While the workpiece is rolling, it is supplemented by high-speed moving plastic elastic sand abrasives that impact the surface of the product, which can accelerate the removal of burrs and rough edge on the edges of the product or inside the holes to improve the surface effect.
  • Another thing to note is that in order to test different processes, we divided the sample into four small pieces and finally determined the optimal deburring plan.

6. Final summary
  • In this case, we demonstrate an automated finishing and trimming process that uses a freezing process to remove burrs and flash from the outer surface and internal holes of rubber shin guards.

Therefore, removing these imperfect surface defects through finishing and polishing methods can greatly improve the durability of the connecting rod.
  • 3. Can you explain how traditional engine connecting rods are polished?
  • The traditional way of polishing connecting rods is manual. It requires a lot of labor and is an annoying process.
    They all use a polishing wheel. Polishing heads of different sizes can be installed on this polishing wheel. According to the different connecting rods, different polishing heads can be replaced for operation. It is also necessary to use polishing paste to speed up the polishing process and make the surface of the connecting rod shiny.
  • 4. How is ShineTec’s engine connecting rod polishing machine polished?
  • Generally speaking, it is divided into two processes. The first is rough finishing, deburring and descaling. Just put your connecting rod blank and tumbling abrasive media into the machine, and then add an appropriate amount of finishing liquid and clean water. After the rough finishing process is completed, the connecting rod can be taken out and transferred to the fine polishing process, which uses polishing to improve the gloss and brightness of the product surface. Just put the connecting rod and the porcelain abrasive media for fine polishing into the machine, add an appropriate amount of polishing chemical liquid and water, and start the machine. The entire polishing process is fully automatic, and you can get a shiny finished connecting rod after the polishing is completed.
  • 5. What are the benefits of using ShineTec’s finishing and polishing machine to polish engine connecting rods?
  • The benefits are many:

    5.1 Excellent surface quality. The traditional manual polishing method depends on the skills and skilled procedures mastered by the workers. The finished products polished by each worker will result in different surface polishing quality, and it is difficult to achieve consistent surface quality of the finished products.
    Polishing with our ShineTec finishing machines can avoid these problems and achieve consistent surface polishing quality.

    5.2 Save man-hours. Polishing each piece by hand requires many man-hours. A worker can only handle one piece of connecting rod at a time. Using ShineTec’s engine connecting rod deburring and descaling solutions, large batches can be processed fully automatically at one time. The operating hours are greatly reduced.

    5.3 low cost. Finishing and polishing mainly consist of two costs. One is the purchase cost of machinery and equipment, and the other is the labor cost of polishing. Manual polishing requires a large number of workers, but using our ShineTec professional finishing machine to polish large quantities of connecting rods only requires one operator. The one-time setup cost of the equipment will be higher than manual polishing tools such as polishing wheels, but it can be used for a long time. The tumbling ceramic media can generally be used for several months or even years after purchase. They are not more expensive than grinding wheels and polishing heads. The key is This saves a lot of labor costs, and overall, the cost of polishing will be greatly reduced.

    5.4 No specially trained polishing operators are required. Hand polishing requires extensive training of operators upfront. Using our mechanized high-volume automated finishing and polishing solutions is simple and requires no dedicated employee training.

    5.5 Not a labor-intensive polishing process. Traditional manual polishing is a typical labor-intensive process and requires a lot of labor. The polishing process of engine piston and connecting rod parts provided by ShineTec is completely mechanized. Only one worker is required to control the machine’s switch, which greatly reduces the use of labor.

    5.6 Non-destructive surface polishing process. The quality of hand polishing depends on the skill of the polisher. Because manpower is uncontrollable, sometimes the polishing process may inevitably cause damage to the product surface. Using ShineTec’s finishing and polishing process, as long as the correct process flow and tumbling ceramic media are determined through process samples in the early stage, the final product of the engine connecting rod will have a uniform surface quality.

    5.7 Extremely low maintenance costs.
    When determining the polishing process for engine connecting rod accessories, routine maintenance costs are also an important factor that should be considered. ShineTec’s deburring and polishing machines are easy to use and operate and do not require additional special tools or trained operators. Therefore, daily maintenance costs are extremely low.

    5.8 Large batch processing. ShineTec’s engine connecting rod polishing machine has the capability of mechanized processing of large batches at one time. It can not only polish the same products in batches, but also deburr and polish connecting rods with different shapes and sizes in the same batch. It can be called an engine connecting rod polisher.
  • 6. Can you explain the differences between polishing by different finishing machines?
  • ShineTec’s finishing and polishing machines mainly have three common types that can be used for professional polishing of engine connecting rods. It can meet the needs of deburring, descaling, degreasing, deflashing, polishing and brightening.

    6.1 Vibratory Finishing Machine。 The vibrating finishing machine is the most commonly used machine for polishing engine connecting rod parts. This model is the easiest to use and operate. The high-strength and elastomer PU lining of the working chamber can protect the connecting rod and tumbling ceramic media from hitting and cutting the inner wall iron plate. It is the most cost-effective and economical engine connecting rod polishing process solution. It can feed large quantities of connecting rods at one time and is suitable for polishing small and medium-sized engine connecting rods.

    6.2 Rectangular Tub Finishing Machine。 Vibratory rectangular tub polishers can be used to polish long wishbones and crossmember links. The rectangular working chamber can be divided into several independent spaces with partitions, so that each connecting rod can be polished in a separate space without collision damage.

    6.3 Centrifugal Barrel Finishing Machine. The centrifugal barrel finisher relies on centrifugal force to drive the working barrel for polishing. It is mainly used to clean and polish connecting rods during the fine polishing stage. The polishing efficiency of this model is very high, and it can produce a mirror-like polishing effect on the surface of the connecting rod within half an hour. Centrifugal barrel finishing machines are divided into two types according to different loading and unloading methods. One is that the barrel has a relatively large capacity and cannot be removed. There is a sealing cover on the barrel, and loading and unloading tumbling media go directly through the opening of the barrel. The other is that the working barrel has a small capacity and can be taken out of the machine. The loading and unloading tumbling media are in the machine. Performed externally, suitable for smaller sized connecting rod polishing.
  • 7. Are there any differences in finishing and polishing between the different abrasive media provided by ShineTec?
  • The abrasive media used to remove burrs, scale and flash from engine connecting rods are also called ceramic tumbling media or polishing media. Each abrasive media corresponds to a different polishing process. Ceramic deburring media are generally used for deburring, deflashing, and descaling. Stainless steel media or polishing porcelain media and high-density porcelain media are generally used to improve brightness. For different shapes and sizes of connecting rods, each tumbling media has different shapes and sizes to choose from.

    7.1 Ceramic Deburring Media. Deburring media is made by mixing brown corundum sand with cutting force with clay, alumina powder, etc., and then sintering it in a high-temperature kiln after shaping. According to the different particle sizes of brown corundum sand, it is divided into heavy cutting, medium cutting and light cutting types, which are suitable for different materials. To measure the quality of a deburring media, there are several indicators such as cutting force, wear resistance, dimensional consistency, hardness, and color difference. The ceramic media produced by ShineTec all use the best first-grade brown corundum new sand, clay raw materials from major manufacturers in the industry, strict molding production processes, and proper sintering temperature control. The above indicators of the tumbling ceramic media are all Ahead of domestic peers. Especially in the key indicator of wear resistance, it is far ahead of competing products. The use time can be extended by 2-3 times, which can save a lot of consumable costs for the manufacturers.

    7.2 Resin Media. Also called plastic media, polyester media, it is obtained by mixing brown corundum sand with resin and curing it. There are also three different finishing levels, heavy cutting, medium cutting, and light cutting. Commonly used shapes include cone, triangle, tetrahedron, and bullet shape. This kind of tumbling finishing media is suitable for polishing soft parts made of aluminum alloy, zinc alloy, copper and other materials.

    7.3 Porcelain Media. This kind of tumbling abrasive media is mainly made of sintered kaolin and alumina powder. It does not contain brown corundum sand and has no cutting force. Therefore, it is mainly used to polish the surface brightness. That is the last fine finishing and polishing process. The quality of the product is mainly determined by the alumina powder content, which ranges from 30% to 70%. The higher the content, the greater the density and specific gravity, and the higher the gloss and brightness of the polished product surface. Of course, sintering temperature is also a key factor affecting quality. Like brown corundum abrasives, tumbling porcelain media have various shapes, including sphere, triangle, oblique triangle, right cylinder, oblique cylinder, three-star, oblique three-star, ellipse, etc., and the specifications and sizes also vary widely.

    7.4 Stainless Steel Media. Since the specific density of stainless steel can reach 7.8 grams/cubic centimeter, which is three times that of porcelain media, the surface of the polished product has the highest density and the highest brightness. Suitable for surface polishing of hard metals. Not suitable for soft metal workpieces such as aluminum alloys and copper. This polishing media has virtually no wear and can be used continuously for decades. The stainless steel media shapes include ball, ballcone, ufo, and pins shapes, and the materials include AISI201, AISI304, AISI316, AISI420, and AISI440C, which are suitable for different acidic or perishable environments.

    7.5 Walnut Shells or Corncob Media. Walnut shell or corncob media is a biodegradable vegetable abrasive. It is mainly used for the drying process after polishing the engine connecting rods. This tumbling abrasive media also comes in different sizes depending on the particle size. In addition to absorbing water and drying, it also has the ability to adsorb impurities and dust on the surface of the connecting rod to the abrasive, playing a cleaning role. It is a dust-free cleaning process.
  • 8. Are there any engine connecting rods that can be polished using ShineTec’s polishing machine?
  • ShineTec’s mass finishing machines are suitable for almost all types of engine connecting rods on the market.

    8.1 Titanium alloy connecting rod. Titanium alloy connecting rods are high-end products on the market because of their strength and durability. Its performance is unmatched by other connecting rod products. A vibratory finishing machine can be used for cleaning and polishing.

    8.2 Cast iron connecting rod. Because it is mainly produced from low carbon steel, its strength is lower than that of stainless steel connecting rods. Due to its low production cost, it is the most widely used connecting rod product on the market. Vibratory finishing machines can be used for finishing and polishing.

    8.3 Machined connecting rods. The material can be produced from different metals, depending on the type of engine used. The most suitable machine is a centrifugal barrel finishing machine, which can quickly remove tool lines, burrs, and scale. A vibrating finisher can also be used.

    8.4 Supercharged engine engine connecting rods. Because it is used in high fatigue strength environments, high-strength materials will be used to produce this connecting rod. Generally used in high-horsepower heavy-duty engines. Proper polishing process can repair surface defects and extend the service life of connecting rods. Suitable for polishing using a centrifugal barrel finishing machine.

    8.5 Forged engine connecting rods. Compared with cast iron connecting rods, forged connecting rods have higher durability. The tighter metal crystal structure formed inside the forged parts ensures higher strength of the product. But forged connecting rods have more surface imperfections. Vibratory or centrifugal barrel finishing machines can be used to polish this product.

    8.6 Aluminum alloy connecting rod. Aluminum alloy connecting rods have better shock absorption performance. It can reduce the stress on the engine crankshaft and extend its service life. Because it is a soft metal, the tumbling finishing media used for deburring, descaling must be a resin tumbling media. The mass finishing machine can be a vibratory finishing machine or a centrifugal barrel finishing machine.
