About Tumbling Barrel Deburring Machine

  • 1．What is the tumbling barrel deburring machine?
  • Tumbling barrel deburring machines are also called rotary barrel finishing machines, rotating tumbler. They use mechanical methods to automatically deburr, descale, derust, finish parts and workpieces in large quantities. Machinery and equipment for surface treatment processes such as deflashing, cleaning, chamfering, degreasing, decontaminating, brightening and improving surface brightness. Its operating principle is to put the product to be polished and the finishing media into the working barrel of the machine, allowing the abrasive and the workpiece to tumble and rotate together, forcing the abrasive and the workpiece to collide and rub against each other to achieve the surface cutting effect.
    The tumbling barrel polishing machine is the simplest structure and the oldest deburring mechanical equipment. The motor drives the barrel to rotate around the central X-axis through a chain or transmission gear. The deburring media in the barrel and the workpiece are turned over and rubbed against each other to achieve the deburring and polishing effect.

  • 2. What is the difference between tumbling barrel deburring and other deburring processes?

  • 2.1 Tumbling barrel deburring is the most traditional mechanical polishing process. Their deburring and polishing principles are similar. The workpiece and the deburring media are mixed together to achieve the deburring effect. The difference is that the barrel tumbler takes the longest time to polish and remove burrs. It is the mechanical equipment tool with the lowest finishing efficiency, but at the same time it is the process equipment with the best surface polishing quality.

    Comparing deburring and cutting efficiency, it can be arranged in this order:
    Centrifugal disc deburring machine > Centrifugal barrel deburring machine > Vibratory deburring machine > Tumbling barrel deburring machine.

    Comparing surface polishing quality, it can be arranged in this order:
    Barrel tumbler > Centrifugal barrel tumbler > Vibrating tumbler > Centrifugal disc tumbler.

    2.2 The tumbling barrel deburring machine uses the dry finishing process when finely deburring and polishing the brightness. That is, the abrasive media and the workpiece are directly mixed together, an appropriate amount of polishing paste is added, and the finishing and polishing is performed directly in the barrel without adding water. Other finishing machines are not allowed to use dry finishing process.

  • 3．Can you tell me how a tumbling barrel deburring machine works?
  • Put the tumbling finising media, the parts to be polished, water, and polishing fluid into the barrel deburring machine according to the corresponding proportions, close the sealing cover of the barrel to make it watertight, and then start the machine. This process can also be called tumbling finishing and polishing process. The abrasive media and the workpiece collide and rub against each other in the barrel, automatically completing the cutting process, reducing the surface roughness of the product, and achieving deburring, descaling, deflashing, chamfering, brightening, burnishing. It is currently the lowest cost, most mature technology and most widely used deburring and polishing solution.

    Since the rotation speed of the barrel is very slow, usually within 50 RPM, the overall processing time of rough finishing, deburring and fine finishing and polishing for each batch will be more than ten hours. It is the slowest finishing and polishing equipment.

    Precision polishing are performed using a dry finishing process. Generally, particle-shaped mirror polishing media with smaller external dimensions are used, such as Corncob polishing media, Walnut shell polishing media, bamboo wood chip, 3P polishing media and other polishing media, with polishing paste, without adding water, can simulate manual polishing with a cloth wheel, so that the surface of the workpiece can achieve a mirror-like polishing effect.

  • 4. What are the benefits of using a tumbling barrel deburring machine to polish parts?
  • Compared with manual polishing, there are definitely many advantages:

    4.1 Automatic large-scale mechanized deburring and polishing. Although the barrel deburring machine takes a relatively long time to finish and polish at one time, dozens hundreds or even tons of workpieces can be put into a batch, making the unit processing time advantage greater.

    4.2 Automatically remove rust and scale. Surface problems such as turning lines and mold lines can also be removed. This is the same as other tumbling finishing machines.

    4.3 Automatic chamfering. Products can be chamfered quickly.

    4.4 Improve surface finish and increase brightness. Make the product surface smoother and brighter. This is the strength of the barrel polishing machine. Its surface finish is of the highest quality.

    4.5 Automatic cleaning and degreasing. It can automatically remove dust, dirt, sludge and other phenomena adsorbed on the surface of the workpiece.

  • 5. Is the operating cost of a tumbling barrel deburring machine high?
  • Compared with manual finishing and polishing, the cost of barrel deburring machine can be said to be very low.
    This is the cheapest automatic finishing and polishing equipment. The one-time purchase cost of the machine can start from several thousand dollars, and it can generally be used for many years. The choice of ordinary abrasive media 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. Etc., buying a few hundred kilograms at a time can generally last for months or even years. The amount of polishing compound is very small and the cost is almost negligible.
    The product workpiece can be fed with about tens of kilograms of material at a time in the smallest tumbling deburring machine. The finishing processing time for a batch is generally 2 hours. The direct cost of deburring and polishing when evenly distributed to each product is minimal.

    On the other hand, the advantage of using a barrel tumbling deburring machine is 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.

  • 6. What optional configurations are available for ShineTec’s tumbling barrel deburring machine?
  • 6.1 protecting mask. A protective net cover can be installed outside the barrel to prevent collisions between people or materials during machine operation.

    6.2 Vibratory separator can be used to screen the abrasive media and parts. It can be used as an auxiliary equipment for the tumbling barrel deburring machine and can be configured separately.

  • 7．Which model of tumbling barrel deburring machine should I choose?
  • You should choose which type of tumbling barrel deburring machine based on the shape, size, material, surface quality requirements, processing quantity and other factors of your product parts.
    There is no limit to the workpiece material suitable for the tumbling barrel deburring machine, and the length is generally within 0.5 meters. However, one requirement is that the workpiece cannot be easily deformed or may be bumped. Because the vertical drop is relatively large when the barrel is turned over, and the impact force of the abrasive media on the workpiece is also large, soft long strips or thin products are easily deformed and damaged.

  • 8. How does ShineTec ensure the quality of the tumbling barrel deburring machine?
  • 8.1 Quality assurance of raw materials. Because the lining of the working barrel of the machine can be rubber or PU, this lining is a wearing part and needs to be replaced regularly. The wear resistance of the colloid is a key quality indicator. The raw materials of our colloids come from major domestic manufacturers and products from Dow Chemical of the United States, so the quality can be guaranteed.

    8.2 Reliable motor quality. The motor is a key component related to product quality. The three-phase asynchronous motors used in our barrel deburring machines all come from well-known professional motor manufacturers in Shanghai, and there is no problem with their quality.

    8.3 Electrical accessories. All are purchased from domestic first-tier manufacturers such as Chint and Delixi.

    9.5 The commonly used power supply for the machine is 380V/3-phase/50Hz. Are there any special power requirements?
    After clarifying the above details, you can place an order.

  • 10．What abrasive media can be used in barrel deburring machines?
  • Abrasive media for rough finishing, fine finishing and polishing:

    10.1 The abrasive used for rough finishing is mainly ceramic deburring media, which is divided into heavy cutting force, medium cutting force and light cutting force.

    10.2 Abrasives for fine fininishing include white corundum finishing media, chrome corundum finishing media, 3P finishing media, etc. Since the grit size of the micropowder contained in them is very fine, some of which are nearly 2000-3000 mesh, it can continuously polish the workpiece surface. Continuous micro-cutting creates a more delicate surface roughness.

    10.3 Polishing media include high-alumina porcelain media, high-density porcelain media (high-alumina porcelain polishing media with an alumina content of more than 95%), stainless steel media, corncob media, walnut shell media, bamboo grain chip, wood grain chip. The main purpose is to improve the gloss and brightness of the workpiece surface.
  • 11. What kind of power supply does the tumbling barrel deburring machine use?
  • In China, it is generally 380V/3-phase/50Hz.
  • 12．What is the daily maintenance of the tumbling barrel deburring machine?
  • Routine maintenance of the tumbling barrel deburring machine is crucial to extending the service life of the machine. Routine maintenance includes the following:

    12.1 Inspection of the lining on the inner wall of the working barrel. Daily use of the machine will cause wear and tear on the lining in the barrel. Do you need to regularly check whether the lining on the inner wall has any holes or wear? If this happens, it needs to be replaced immediately, otherwise it will cause damage to the barrel.

    12.2 After each loading, check whether the water added in the barrel is too little or too much. The water surface of the barrel polishing machine should not exceed the material by 20mm. Too much water will buffer the force exerted by the abrasive on the workpiece surface and reduce the deburring efficiency; Too little water will cause damage to the surface of the workpiece, the abrasive will easily break and the colloid in the barrel will wear too quickly.

    12.3 Loading capacity of tumbling finishing media and workpiece. We recommend that the ratio of abrasives to workpieces is 3:1. Too little abrasives will cause collisions between workpieces and damage the product surface; too much abrasives will reduce the grinding efficiency of the product.
    Note that the overall volume of materials and water in the working barrel does not exceed 60% of the inner volume of the barrel.

    12.4 Check the abrasive media debris for stuck holes and seams. The abrasives in the barrel will become smaller and smaller after long-term use. In addition, a lot of debris formed by the workpiece and the abrasives will be produced during the grinding process. If the width of these impurities is less than 1mm, they may block the holes and seams inside the parts, affecting the deburring and polishing effect of the workpiece. If stuck holes occur, the tumbling finishing media should be screened to remove the debris and impurities, and the machine should be restarted.

    12.5 Water temperature detection. Long-term operation of the machine will cause the temperature inside the working barrel to become very high. Excessively high water temperature will accelerate the aging rate of the colloid, so if your product needs to be polished for more than ten hours, please use a rubber-lined barrel, because the high temperature resistance of rubber is better than that of PU lining.

  • 13．What industries can the tumbling barrel deburring machine be used in?
  • Barrel deburring machines are widely used in automotive parts, aerospace, medical equipment, mechanical parts, plastic products, 3C digital, metal casting, electronic devices, hardware parts, kitchen supplies, 3D printing, textile workpieces, powder metallurgy, electrical components, It is widely used in industries such as minting, jewelry, instrumentation, and handicraft accessories.
  • 14．Are there any disadvantages to tumbling barrel deburring machines?
  • The main disadvantage is that it cannot control a specific part of the surface of the finishing product, because it is an overall grinding process. For example, for a product with inconsistent sizes at both ends, you want to make the two ends of the product uniform in size by finishing only the large end, but this is not possible.

    The surface quality cannot achieve the effect of 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 cannot be processed. For example, burrs and flash exceeding 2mm.

    It is not suitable for some workpiece that are easy to deform and are afraid of being bumped.

  • 15. Does the tumbling barrel deburring machine require specially trained technicians to operate it?
  • Unnecessary. The operation of this machine is very simple. Just put the abrasive media, workpiece, water and appropriate amount of chemical finishing liquid into the barrel. The machine has a timing function. After starting the machine, the worker can leave to handle other matters. When the set time is up, the machine will automatically shut down.

The abrasive media and the workpiece collide and rub against each other in the barrel, automatically completing the cutting process, reducing the surface roughness of the product, and achieving deburring, descaling, deflashing, chamfering, brightening, burnishing. It is currently the lowest cost, most mature technology and most widely used deburring and polishing solution.

    Since the rotation speed of the barrel is very slow, usually within 50 RPM, the overall processing time of rough finishing, deburring and fine finishing and polishing for each batch will be more than ten hours. It is the slowest finishing and polishing equipment.

    Precision polishing are performed using a dry finishing process. Generally, particle-shaped mirror polishing media with smaller external dimensions are used, such as Corncob polishing media, Walnut shell polishing media, bamboo wood chip, 3P polishing media and other polishing media, with polishing paste, without adding water, can simulate manual polishing with a cloth wheel, so that the surface of the workpiece can achieve a mirror-like polishing effect.

  • 4. What are the benefits of using a barrel finishing machine to polish parts?
  • Compared with manual polishing, there are definitely many advantages:

    4.1 Automatic large-scale mechanized deburring and polishing. Although the barrel deburring machine takes a relatively long time to finish and polish at one time, dozens hundreds or even tons of workpieces can be put into a batch, making the unit processing time advantage greater.

    4.2 Automatically remove rust and scale. Surface problems such as turning lines and mold lines can also be removed. This is the same as other tumbling finishing machines.

    4.3 Automatic chamfering. Products can be chamfered quickly.

    4.4 Improve surface finish and increase brightness. Make the product surface smoother and brighter. This is the strength of the barrel polishing machine. Its surface finish is of the highest quality.

    4.5 Automatic cleaning and degreasing. It can automatically remove dust, dirt, sludge and other phenomena adsorbed on the surface of the workpiece.

  • 5. Is the operating cost of a barrel finishing machine high?
  • Compared with manual finishing and polishing, the cost of rotary barrel tumbling machine can be said to be very low.
    This is the cheapest automatic finishing and polishing equipment. The one-time purchase cost of the machine can start from several thousand dollars, and it can generally be used for many years. The choice of ordinary abrasive media 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. Etc., buying a few hundred kilograms at a time can generally last for months or even years. The amount of polishing compound is very small and the cost is almost negligible.
    The product workpiece can be fed with about tens of kilograms of material at a time in the smallest tumbling deburring machine. The finishing processing time for a batch is generally 2 hours. The direct cost of deburring and polishing when evenly distributed to each product is minimal.

    On the other hand, the advantage of using a barrel tumbling deburring machine is 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.

  • 6. What optional configurations are available for ShineTec’s barrel finishing machine?
  • 6.1 protecting mask. A protective net cover can be installed outside the barrel to prevent collisions between people or materials during machine operation.

    6.2 Vibrating separator can be used to screen the abrasive media and parts. It can be used as an auxiliary equipment for the tumbling barrel deburring machine and can be configured separately.

  • 7．Which model of barrel finishing machine should I choose?
  • You should choose which type of rotary barrel tumbling machine based on the shape, size, material, surface quality requirements, processing quantity and other factors of your product parts.
    There is no limit to the workpiece material suitable for the rotary barrel tumbling machine, and the length is generally within 0.5 meters. However, one requirement is that the workpiece cannot be easily deformed or may be bumped. Because the vertical drop is relatively large when the barrel is turned over, and the impact force of the abrasive media on the workpiece is also large, soft long strips or thin products are easily deformed and damaged.

  • 8. How does ShineTec ensure the quality of the barrel finishing machine?
  • 8.1 Quality assurance of raw materials. Because the lining of the working barrel of the machine can be rubber or PU, this lining is a wearing part and needs to be replaced regularly. The wear resistance of the colloid is a key quality indicator. The raw materials of our colloids come from major domestic manufacturers and products from Dow Chemical of the United States, so the quality can be guaranteed.

    8.2 Reliable motor quality. The motor is a key component related to product quality. The three-phase asynchronous motors used in our barrel deburring machines all come from well-known professional motor manufacturers in Shanghai, and there is no problem with their quality.

    8.3 Electrical accessories. All are purchased from domestic first-tier manufacturers such as Chint and Delixi.

    9.3 Choose the appropriate machine processing capacity, provide the space size of your work area, and determine the machine model.

    9.4 Confirm whether additional auxiliary equipment is required, such as vibratory separator, additional wearing spare parts, etc.

    9.5 The commonly used power supply for the machine is 380V/3-phase/50Hz. Are there any special power requirements?
    After clarifying the above details, you can place an order.

  • 10．What abrasive media can be used in barrel finishing machines?
  • Abrasive media for rough finishing, fine finishing and polishing:

    10.1 The abrasive used for rough finishing is mainly ceramic deburring media, which is divided into heavy cutting force, medium cutting force and light cutting force.

    10.2 Abrasives for fine fininishing include white corundum finishing media, chrome corundum finishing media, 3P finishing media, etc. Since the grit size of the micropowder contained in them is very fine, some of which are nearly 2000-3000 mesh, it can continuously polish the workpiece surface. Continuous micro-cutting creates a more delicate surface roughness.

    10.3 Polishing media include high-alumina porcelain media, high-density porcelain media (high-alumina porcelain polishing media with an alumina content of more than 95%), stainless steel media, corncob media, walnut shell media, bamboo grain chip, wood grain chip. The main purpose is to improve the gloss and brightness of the workpiece surface.。

  • 11. What kind of power supply does the barrel finishing machine machine use?
  • In China, it is generally 380V/3-phase/50Hz.
  • 12．What is the daily maintenance of the barrel finishing machine?
  • Routine maintenance of the barrel finishing machine is crucial to extending the service life of the machine. Routine maintenance includes the following:

    12.1 Inspection of the lining on the inner wall of the working barrel. Daily use of the machine will cause wear and tear on the lining in the barrel. Do you need to regularly check whether the lining on the inner wall has any holes or wear? If this happens, it needs to be replaced immediately, otherwise it will cause damage to the barrel.

    12.2 After each loading, check whether the water added in the barrel is too little or too much. The water surface of the barrel polishing machine should not exceed the material by 20mm. Too much water will buffer the force exerted by the abrasive on the workpiece surface and reduce the deburring efficiency; Too little water will cause damage to the surface of the workpiece, the abrasive will easily break and the colloid in the barrel will wear too quickly.

    12.3 Loading capacity of tumbling finishing media and workpiece. We recommend that the ratio of abrasives to workpieces is 3:1. Too little abrasives will cause collisions between workpieces and damage the product surface; too much abrasives will reduce the grinding efficiency of the product.
    Note that the overall volume of materials and water in the working barrel does not exceed 60% of the inner volume of the barrel.

    12.4 Check the abrasive media debris for stuck holes and seams. The abrasives in the barrel will become smaller and smaller after long-term use. In addition, a lot of debris formed by the workpiece and the abrasives will be produced during the grinding process. If the width of these impurities is less than 1mm, they may block the holes and seams inside the parts, affecting the deburring and polishing effect of the workpiece. If stuck holes occur, the tumbling finishing media should be screened to remove the debris and impurities, and the machine should be restarted.

    12.5 Water temperature detection. Long-term operation of the machine will cause the temperature inside the working barrel to become very high. Excessively high water temperature will accelerate the aging rate of the colloid, so if your product needs to be polished for more than ten hours, please use a rubber-lined barrel, because the high temperature resistance of rubber is better than that of PU lining.
  • 13．What industries can the barrel finishing machine be used in?
  • Barrel Finishing Machines are widely used in automotive parts, aerospace, medical equipment, mechanical parts, plastic products, 3C digital, metal casting, electronic devices, hardware parts, kitchen supplies, 3D printing, textile workpieces, powder metallurgy, electrical components, It is widely used in industries such as minting, jewelry, instrumentation, and handicraft accessories.
  • 14．Are there any disadvantages to barrel finishing machines?
  • The main disadvantage is that it cannot control a specific part of the surface of the finishing product, because it is an overall grinding process. For example, for a product with inconsistent sizes at both ends, you want to make the two ends of the product uniform in size by finishing only the large end, but this is not possible.

    The surface quality cannot achieve the effect of 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 cannot be processed. For example, burrs and flash exceeding 2mm.

What is the tumbling deburring machine?

About Tumbling Deburring Machine

  • 1．What is the tumbling deburring machine?
  • The tumbling deburring machine is also called a mass finishing machine, polishing tumbler. It uses mechanical methods to automatically and efficiently deburr and descale parts and products and workpieces in large quantities. It’s a machinery and equipment for surface treatment processes such as derusting, deflashing, cleaning, chamfering, degreasing, decontaminating, polishing, brightening. It works by combining the products that need polishing with abrasive media. Put it into the working barrel of the machine and let the abrasive and the workpiece tumble and rotate together, forcing the tumbling chip and the workpiece to collide and rub against each other to achieve the surface cutting effect.
    According to different operating modes, tumbling deburring machines are divided into the following four types:

    1.1 Vibrating deburring machine. It uses three-dimensional spiral vibration to drive the deburring media and the workpiece to move together to achieve the deburring effect.

    1.2 Centrifugal barrel deburring machine. Similar to the operation of a Ferris wheel, the motor drives the large centrifugal disk to rotate, causing the four barrels on the disk to rotate at high speed, driving the deburring media and the workpiece to move together to achieve the deburring effect.

    1.3 Centrifugal disc deburring machine. The chassis drives the barrel to rotate at a high speed on the horizontal plane, and the deburring media and workpieces also tumble and rotate in the barrel to achieve the deburring effect.

    1.4 Tumbling barrel deburring machine. It is the simplest structure of deburring motion. The barrel rolls around the central X-axis, and the deburring media in the barrel rolls together with the workpiece to achieve the deburring effect.

  • The main difference is that tumbling deburring is the lowest-cost automated batch mechanical finishing process.
    The advantage of this deburring method is that it can be applied to surface deburring treatments such as irregular and complex-shaped product parts, finishing of the inner and outer surfaces of workpieces. The materials processed range from non-ferrous metals, ferrous metals, powder metallurgy, plastics, acrylic, rubber, bamboo, stone, glass and other materials. It can be said that there is almost no material that cannot be processed.

    In addition, the operation is simple. As long as the loading and unloading are completed, the machine can be started unattended. No special technical training is required.
    Other deburring and polishing processes, such as manual deburring and polishing, robot deburring and polishing, chemical deburring and polishing, electrolytic deburring and polishing, etc., either require professional training, or the working environment is harsh and harmful to the environment, or the efficiency is not high. Therefore, this process is the most widely used surface deburring treatment method.

What is the centrifugal disc finishing machine?

Centrifugal Disc Finishing Machine

  • 1．What is the centrifugal disc finishing machine?
  • The centrifugal disc finishing machine is a barrel deburring and polishing finisher with the highest finishing efficiency. Its operating principle is to use a centrifugal rotating disk connected to a motor to drive the working barrel connected to it to rotate at a high speed, so that the ceramic media rotates at high speed together with the product workpiece, but a circle of PU lining tooth tip is specially poured on the inner wall of the barrel. Under the impact of the ceramic media and water flow, a feedback force in the opposite direction is generated, forcing the abrasive media and the workpiece to collide and rub against each other to achieve the surface cutting effect. This kind of grinding efficiency can be 10-30 times higher than other finishing machines, and you can get the surface finishing effect you need in a very short time.
    The barrel speed can reach 60-180 rpm, and the speed is controlled by the speed-regulating motor on the machine.

    ShineTec's centrifugal disc finishing machine
  • 2. What is the difference between centrifugal disc finishing machine and other finishing machine?
  • The main difference is that the finishing efficiency of the centrifugal disc finishing machine is the highest among all machines. Because the workpiece is always in a continuous cutting process in the abrasive media, this kind of polishing machine takes the shortest time and the fastest speed when finishing.
    When the machine is running, the probability of collision between workpieces is minimal because the workpiece and tumbling media are always moving in the same direction.
    Suitable for processing small to medium sized products. Because the diameter of the working bowl of this type of machine generally does not exceed 1 meter, and there is a column in the middle of the bowl, so workpieces exceeding 200mm cannot be placed. Even if it can be put into the machine at an angle, the workpiece will be stuck on the inner wall due to the high-speed rotation. If it is often stuck, it will break the PU lining and also cause the product to deform.
    The centrifugal disc finishing machine has the strongest cutting force, so it is suitable for finishing some parts and workpieces with long burrs, large flash, and relatively thick oxide scale.

    barrel ring of centrifugal disc finishing machine
  • 3．Can you tell me how a centrifugal disc finishing machine works?
  • 3.1 The working barrel of the centrifugal disc finishing machine is open, and the entire barrel can be turned over and tilted downward to facilitate loading and unloading of materials.

    3.2 Put the finishing media and product workpieces into the barrel together, turn the barrel over to straighten it, keep the mouth of the barrel upward, then add water and an appropriate amount of finishing liquid. The water surface should not cover the material for about 30mm, and only a small amount of chemical finishing liquid needs to be added. Generally, a 50L machine only needs to add about 30 ml. Note that the volume of materials in the barrel should not exceed 60% of the total volume of the barrel, and then the machine can be started.

    3.3 Turn the speed-regulating motor knob on the control panel to gradually adjust the barrel speed from low to high, and finally keep the barrel at the required speed. The entire finishing process is completed automatically, in the meantime, the operator can leave to handle other work tasks without having to stay at the machine.

    3.4 After the required finishing time is reached, adjust the speed of the barrel to keep the working barrel rotating slowly, add clean water to the top of the barrel to rinse, open the water flow valve at the bottom of the barrel, let the sewage inside flow out, and inject clean water above to complete the cleaning process.

    3.5 After cleaning is completed, turn the barrel over and pour out the workpiece and abrasive media. You can also configure a special vibrating separator to separate the abrasives and workpieces automatically, or it can manually screen and pick up the pieces to complete an finishing batch.

  • 4. What are the benefits of using a centrifugal disc finishing machine to polish parts?
  • Compared with manual polishing, there are definitely many advantages:

    4.1 Automatic deburring, deflashing, chamfering. Defects caused during workpiece processing that may cause harm to users can be automatically removed in large quantities.

    4.2 Automatically derusting and descaling. Surface problems such as turning lines and mold lines can also be removed.

    4.3 Automatic chamfering. Products can be chamfered quickly

    4.4 Improve surface finish and increase brightness. Make the product surface smoother and brighter.

    4.5 Automatic cleaning and degreasing. It can automatically remove dust, dirt, sludge and other phenomena adsorbed on the surface of the workpiece.

  • 5. Is the operating cost of a centrifugal disc finishing machine high?
  • Compared with manual finishing and polishing, the cost of rotary barrel tumbling machine can be said to be very low.
    This is the cheapest automatic finishing and polishing equipment. The one-time purchase cost of the machine can start from several thousand dollars, and it can generally be used for many years. The choice of ordinary abrasive media 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. etc., buying a few hundred kilograms at a time can generally last for months or even years. The amount of chemical finishing liquid is very small and the cost is almost negligible.
    A 50L centrifugal disc finisher can feed about 50 kilograms of product workpieces at a time. The grinding processing time for a batch is generally 30-60 minutes. The direct cost of grinding and polishing when evenly distributed to each product is minimal.
    On the other hand, in terms of saving labor costs, the advantages of using centrifugal disc finisher 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.

  • 7．Which model of centrifugal disc finishing machine should I choose?
  • You should choose the model of centrifugal disc finishing machine based on the specifications and dimensions of your product parts.
    Generally speaking, if the length of your workpiece is less than 50mm, we recommend you use a 50L disc finisher; if the workpiece length is about 50-100mm, use a 120L finisher; if the workpiece length is about 100-150mm, use a 200L capacity machine. For workpieces exceeding 150mm, it is not recommended to use an centrifugal disc finishing machine.
    For this disc finishing machine, we also recommend that the mixing ratio of abrasive media to workpiece is about 3:1.

  • 8. What spare parts are available for centrifugal disc finishing machines?
  • The bottom plate of the centrifugal disc, the barrel ring, and the gasket between the barrel ring and the bottom plate are parts that need to be replaced frequently.
    Both the disc and the barrel ring have PU linings, which are prone to wear and tear during daily finishing. When the lining of these two parts is found to be damaged, spare parts need to be replaced immediately.
    Generally, the barrel ring needs to be replaced every 3-6 months. This mainly depends on the actual usage.
    After the gasket is worn, abrasive debris will get stuck in the gap between the barrel ring and the disc, causing the centrifuge disc to get stuck. It is also a key wearing part.

  • 9. How does ShineTec ensure the quality of the centrifugal disc finishing machine?
  • 9.1 Quality assurance of raw materials. Because the lining of the working barrel of the machine is PU, this lining 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 major domestic manufacturers and products from Dow Chemical of the United States, so the quality can be guaranteed.

    9.2 Reliable motor quality. The motor is a key component related to product quality. The three-phase asynchronous motors used in our barrel deburring machines all come from well-known professional motor manufacturers in Shanghai, and there is no problem with their quality.

    9.3 Electrical accessories. All are purchased from domestic first-tier manufacturers such as Chint and Delixi.

    9.4 Steel plate profiles. Purchased from Shanghai Baosteel Products.

    9.5 Manufacturing Guaranteed. Product production is controlled by skilled workers with many years of front-line production experience, adhering to the spirit of craftsmanship to ensure product quality.

  • 10．How to order a centrifugal disc finishing machine?

    10.3 Choose the appropriate machine processing capacity, provide the space size of your work area, and determine the machine model.

    10.4 Confirm whether additional auxiliary equipment is required, such as vibratory separator, additional wearing spare parts, etc.

    10.5 The commonly used power supply for the machine is 380V/3-phase/50Hz. Are there any special power requirements?
    After clarifying the above details, you can place an order.

  • 11．What abrasive media can be used in centrifugal disc finishing machine?
  • Tumbling media for rough finishing, fine finishing and polishing:

    11.1 The finishing media used for rough finishing is mainly ceramic deburring media, which is divided into heavy cutting force, medium cutting force and light cutting force.

    11.2 Finishing media for fine fininishing include white corundum finishing media, chrome corundum finishing media, 3P finishing media, etc. Since the grit size of the micropowder contained in them is very fine, some of which are nearly 2000-3000 mesh, it can continuously polish the workpiece surface. Continuous micro-cutting creates a more delicate surface roughness.

    11.3 Polishing media include high-alumina porcelain media, high-density porcelain media (high-alumina porcelain polishing media with an alumina content of more than 95%), stainless steel media, corncob media, walnut shell media, bamboo grain chip, wood grain chip. The main purpose is to improve the gloss and brightness of the workpiece surface.

  • 12．What kind of power supply does the centrifugal disc finishing machine use?
  • In China, it is generally 380V/3-phase/50Hz.
  • 13．What is the daily maintenance of the centrifugal disc finishing machine?
  • Like other finishing machines, routine maintenance of centrifugal disc finisher is crucial to extending the service life of the machine. Routine maintenance includes the following:

    13.1 Check the PU lining on the inner wall of the centrifuge barrel. Daily use of the machine will cause wear and tear on the PU lining in the barrel. You need to regularly check whether there are holes in the PU lining on the inner wall. Are there any defects in the ridges? If damaged, the barrel ring needs to be replaced.

    13.2 Before each start, check whether the water added to the barrel is too little or too much. The water surface is generally no more than 30mm above the material. Too little water will cause damage to the surface of the workpiece, the abrasive media will easily break, and the PU lining in the barrel will wear too fast. Too much water will cause the liquid to splash around when the barrel rotates at high speed, affecting the environment.

    13.3 Loading capacity of abrasive media and workpiece. We recommend that the ratio of abrasives to workpieces is 3:1. Too little tumbling media will cause collisions between workpieces and damage the product surface; too much abrasives media will reduce the grinding efficiency of the product.
    Note that the overall volume of materials in the working barrel does not exceed 60% of the inner volume of the barrel.

    13.4 Check for jamming of abrasive debris. The abrasives in the barrel will become smaller and smaller after long-term use. In addition, a lot of debris formed by workpieces and abrasives will be produced during the grinding process. If the width of these impurities is less than 1mm, they may get stuck between the barrel ring and the disc. The gap causes the machine to get stuck and unable to rotate. At this time, you need to shut down the machine, remove the barrel ring, clean the impurities, and restart the machine.

    13.5 Water temperature detection. If the centrifugal disc finishing machine runs continuously for more than 2 hours, the temperature inside the working barrel will become very high. Excessively high water temperature will speed up the aging of PU lining, so you need to cool down the temperature in the barrel by replacing the water.

  • 14．What industries can the centrifugal disc finishing machine be used in?
  • Centrifugal disc finisher are widely used in automotive parts, aerospace, medical equipment, mechanical parts, plastic products, 3C digital, metal casting, electronic devices, hardware parts, kitchen supplies, 3D printing, textile workpieces, powder metallurgy, electrical components, It is widely used in industries such as minting, jewelry, instrumentation, and handicraft accessories.
  • 15．Are there any disadvantages to centrifugal disc finishing machine?
  • The processing capacity of the centrifugal disc finisher is less thanVibratory finisher and Tumbling barrel finisher. The processing volumes of commonly used models are generally 50L and 120L, so the amount loaded at one time is relatively small.
    Due to the small diameter of the barrel, workpieces with a length of more than 150mm are not suitable for finishing and polishing with this model, which may cause deformation and damage to the workpiece.
    Since there is a gasket between the working barrel ring and the disc, if the gasket is worn, a gap will appear, causing abrasive debris or impurities to get into the gap and jam the machine. If not dealt with in time, the motor may burn out.
  • 16．Does the centrifugal disc finishing machine require specially trained technicians to operate it?
  • Unnecessary. The operation of this machine is very simple. Just put the abrasive media, workpiece, water and appropriate amount of chemical finishing liquid into the barrel. The machine has a timing function. After starting the machine, the worker can leave to handle other matters. When the set time is up, the machine will automatically shut down. All that is needed is to unload the material and take out the workpiece to complete the finishing and polishing process. Therefore no special technical training is required for employees.
  • 17．What surface treatments can the centrifugal disc finishing machine perform?
  • 17.1 Deburring, deflashing, chamfering. Defects caused during workpiece processing that may cause harm to users can be automatically removed in batches.

    17.2 Derusting and descaling. Surface problems such as turning lines and mold lines can also be removed.

    17.3 Improve surface finish and increase brightness. Make the product surface smoother and brighter.

    17.4 Cleaning and degreasing. It can automatically remove dust, dirt, sludge and other phenomena adsorbed on the surface of the workpiece.

  • 18．What are the tumbling media suitable for centrifugal disc finishing machine?
  • Depending on the shape, material, specifications and sizes of your parts, you need to choose different types of abrasive media. Abrasives that can be used in the machine are: tumbling deburring media, tumbling porcelain media, high-density porcelain media, polyester media, white corundum finishing media, 3P precise finishing media, walnut shell mirror polishing media , corncob drying media,etc.
    Improper selection of abrasives during the finishing process will affect grinding efficiency and may even cause damage to the workpiece.

What is the centrifugal barrel finishing machine?

About Centrifugal Barrel Finishing Machine

  • 1．What is the centrifugal barrel finishing machine?
  • Centrifugal barrel finishing machine, also called centrifugal disc finisher, is a type of high-efficiency tumbling and polishing machine. It operates like a Ferris wheel commonly found in parks. The four working barrels are installed on a wheel bracket that rotates radially around the center. As the bracket rotates, the barrels also perform radial centrifugal high-speed rotation. At the same time, the barrels also rotate. Therefore, there are two spin moves of the working barrels throughout the process.
    The working barrel is preloaded with product workpieces, tumbling media and water, the finishing compound liquid is filled with 60%-80% of the total volume. During the high-speed rotation of the barrel, the tumbling media and the workpiece collide and rub against each other, which plays a finishing and polishing role in deburring and descaling on the surface of the workpiece.
    Depending on the volume of the centrifugal working barrel, there are a variety of models to choose from, ranging from 30 liters to 300 liters, which can handle workpieces of different sizes.

    ShineTec's centrifugal barrel finishing machine

  • 2. What is the difference between centrifugal barrel finishing machine and other finishing machine?
  • 2.1 The centrifugal barrel finishing machine is a highly efficient grinding and polishing equipment. Because its operating speed is far faster than that of vibratory finishing and polishing machines and barrel tumbling finishing and polishing machines, the processing time of the same workpiece by the centrifugal barrel machine is generally within 30 minutes, while vibratory finisher may take several hours, and barrel tumbling finisher even takes ten a couple of hours. For centrifugal disc finisher, the processing time of a> is relatively close.

    2.2 The centrifugal barrel finishing machine is suitable for grinding and polishing some precision product parts with small dimensions and small surface burrs. Because the processing volume of the working barrel of commonly models is 7.5 liters to 20 liters, and the width of the barrel is about 280-450mm, products that exceed the length cannot be put into the barrel. Also, if the product is too heavy, it will have a great impact on the barrel wall during high-speed rotation, which can easily damage the PU lining, causing problems such as damage and shedding of the PU.

    2.3 Special molds can also be customized inside the working barrel to separate the inside of the barrel to form separate cavities. In this way, some larger workpieces can be ground and polished individually in independent cavities without fear of collision with each other.

    2.4 The centrifugal barrel finishing machine is also suitable for processing some product workpieces with complex irregular shapes. In addition, cross holes, dead corners, pipelines, and gaps in the workpiece can also be processed by using special abrasive media. Because the machine is rotating at high speed, the abrasive can reach these the holes on parts for polishing due to the centrifugal force. Of course, if the pores and pipelines are too long and too deep, there is nothing you can do, such as deep holes exceeding 200mm.

  • 3. How does ShineTec ensure the quality of centrifugal barrel finishing machine?

  • 11. What equipment and materials are included in the polishing solution of the centrifugal barrel finishing machine?
  • The use of centrifugal barrel finishing machines to process workpieces includes three parts:

    11.1 Polishing machine. The centrifugal barrel finisher consists of a wheel frame, a centrifugal barrel, a motor, and some mechanical components and transmission components.

    11.2 Tumbling media. Choosing the right abrasive media is a key factor in achieving good grinding results for your workpiece in a centrifugal barrel machine. Including the shape, size, cutting force grade of the abrasive, and whether it will block the holes of the workpiece, these aspects need to be considered.

    11.3 Finishing compound liquid. The finishing fluid, water, abrasive media and workpiece are mixed and added to the barrel. The water needs to cover the material surface by about 30mm, and the total volume does not exceed 80% of the volume of the barrel. Only a small amount of finishing liquid is needed. Generally, for a 30L centrifugal finisher, only about 25ml of finishing fluid is poured into each barrel.

    11.4 Notes. After loading, check the sealing condition of the barrel. After tightening the sealing cover, each barrel must be placed horizontally on the ground to see if there is any water leakage. All four centrifuge barrel must be loaded into the machine before the machine can be operated. If you only need to load two barrels, put the barrels in diagonal positions to allow the wheel rack to keep the weight balanced. Be careful not to install only one barrel or three barrels, or the two barrels are not in diagonal positions. Otherwise, the roulette frame will be easily damaged when it rotates at high speed in an unbalanced state. Before starting the machine, gently turn the wheel frame by hand to see if there is any abnormal sound. Only when everything is normal you can start the machine.

  • 5．What is the price of a vibratory tumbler?
  • As can be seen from the above cost analysis, the price of buying a vibratory tumbler is not expensive. It can be said that if your product is suitable for using a vibratory finishing machnie for deburring, descaling and other processes, then you can believe that you have obtained extremely low finishing and polishing processing costs.
  • 6．What factors should you consider when purchasing a vibratory tumbler?
  • The first factor to consider is the working capacity of the machine, that is, the volume of the machine’s working bowl. So first, you need to confirm what the quantity or weight of the workpieces you need to process every day is? How much product do you need to finish per batch?
    There is a rough ratio between volume and processing capacity for your reference. Generally, for a working volume of 100 liters, the actual loading capacity is about 80%, that is, 80 liters, and the corresponding loading weight is about 80 kilograms, that is, the total weight of tumbler media + workpiece does not exceed 80 kilograms. Based on this ratio, based on your products need to be finished and polished, you can roughly estimate the volume of a vibratory tumbler.
    Another factor that needs to be considered is whether it is necessary to fine-finish and polish the surface brightness of the product after rough deburring, descaling and other operations? Because the tumbler media used for fine finishing are different from those used for rough finishing, if your product still needs fine finishing after rough finishing, you will need to replace the abrasive media in the machine. If the daily processing volume is relatively large, you will need to purchase two machines, one is used for rough finishing and the other is used for fine polishing.
  • 7. Can you tell me how a vibratory tumbler polishes?
  • First, you need to put the tumbler media and the workpiece into the machine, add an appropriate amount of clean water, the water surface should not cover the abrasive media, only need a layer of water at the bottom of the bowl, then add an appropriate amount of finishing liquid, generally a 100L machine only needs Just add about 100ml.
    After the machine is started, observe the tumbling and rotating direction of the abrasive and the workpiece in the working bowl. The normal grinding movement is that the abrasive media and the workpiece tumble from the outside to the inside of the bowl, and at the same time perform a clockwise rotation. These two movements in the machine are a constant cycle. If the direction is wrong, please adjust the angle between the eccentric weights at the upper and lower ends of the motor, or reverse the wiring positions of the two live wires of the three-phase power cord.
    After the finishing process is completed, rinse it with clean water while the machine is running, and then you can pick it up. Machines with a volume of less than 100L can manually pick up items directly from the machine, and those with a volume above 100L can use the machine’s built-in separator to automatically screen and pick out items.

  • 8. How long does it take for a vibratory tumbler to finish and polish?
  • The finishing and polishing time depends on the actual surface condition of the parts. There are two main factors that affect grinding time, one is the cutting force level of the tumbler media, and the other is the size of the machine. The tumbler media with heavy cutting has strong cutting force, the shorter the cutting time, and vice versa. The larger the working bowl volume of the machine, the greater the tumbling force of the abrasive and workpiece inside, the greater the cutting force, and the corresponding shorter time. Operations such as rough cutting, deburring, and descaling can take anywhere from a few minutes to a few hours, but fine finishing and polishing generally takes about 30 minutes per batch.
  • 9. Can I use the same vibratory tumbler for deburr and brighten?
  • Yes, as long as your workpieces is in time to deal with the quantity. But the tumbler media used in finishing and polishing are different, and the media need to be replaced each different process. This process is time-consuming, so it is recommended to prepare two vibrating tumblers at ordinary times, one for rough finishing and the other for fine finishing and polishing.
