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.

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.

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.

    ShineTec's tumbling deburring machine
  • 2. What is the difference between tumbling deburring and other deburring processes?
  • 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.

  • 3．Can you tell me how a tumbling deburring machine works?
  • Put the tumbling deburring media, product workpiece to be polished, water, and finishing liquid into the tumbling machine according to the corresponding proportions, and use mechanical movements such as vibrating, centrifugal barrel, disc, tumbling to cause the deburring media and workpieces to collide and rub against each other, automatically complete the cutting process, reduce the surface roughness of the product, and achieve surface effects such as deburring, descaling, deflashing, chamfering, brightening and improving surface gloss and brightness. It is currently the polishing solution with the lowest cost, the most mature technology and the most widely used. If you don’t know where to find the best deburring and polishing methods for product parts and workpieces, you may wish to contact us, maybe we can help you solve your problem.

  • 4. What are the benefits of using a tumbling 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 deburring 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 liquid 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 deburring machine?
  • 6.1 Sound hood. Can be used in vibrating deburring machines and centrifugal disc deburring machines. Reduce machine noise and prevent foam splashing caused by deburring fluid during work.

    6.2 Automatic separating of deburring media and workpieces. It can be built into centrifugal barrel and disc deburring machines, or can be configured separately as an auxiliary equipment for vibrating deburring machines and barrel tumbling deburring machines.

    6.3 Quantitative automatic filling of clean water and finishing fluid. The mixed solution of water and finishing fluid can be pumped into the machine at a fixed speed and quantitatively, and the filling amount of different batches of polishing can be completely controlled to achieve a completely balanced surface quality.

    6.4 Frequency conversion speed regulation function. A frequency converter is also installed in the electrical control box, which is suitable for adjusting the different operating speeds of vibration finishing machines, centrifugal finishing machines, and barrel finishing machines. The centrifugal disc finishing machine is not used because it is originally equipped with a speed-adjustable motor.

  • 7．Which model of tumbling deburring machine should I choose?
  • You should choose which type of tumbling deburring machine based on the shape, size, material, surface quality requirements, processing quantity and other factors of your product parts.

    7.1 Vibratory deburring machineis a general-purpose deburring machine. If the longest dimension of your product is within 500mm, and the product requires a large amount of processing per day, such as hundreds of kilograms to several tons, then it is most appropriate to choose a vibratory deburring machine.

    7.2 Centrifugal barrel deburring machinesare suitable for processing small precision parts. If your product size is within 100mm and the daily processing quantity is tens of kilograms, then the centrifugal barrel deburring machine is most suitable.

    7.3 Centrifugal disc deburring machinehas the highest deburring efficiency. If your product size is within 200mm, is not afraid of impact deformation, and the daily processing volume is within one to two hundred kilograms, then the centrifugal disc deburring machine is very suitable.

    7.4 Tumbling barrel deburring machineis the deburring machine with the lowest polishing efficiency but the best polishing quality. If you have high requirements for the surface brightness and gloss of the product and hope to achieve an effect close to mirror polishing, then the barrel polishing machine can do the job.

    7.5 Rectangular tub deburring machine, It is a type of vibrating polishing machine, suitable for processing workpieces with a length of more than 500mm. The grinding efficiency is higher than that of barrel polishing machine but lower than that of ordinary vibrating bowl finishing machine.

  • 8. How does ShineTec ensure the quality of the tumbling 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.

    8.4 Steel plate profiles. Purchased from Shanghai Baosteel Products.

    8.5 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.

  • 9. How to order a tumbling deburring machine?
  • Please confirm the following basic requirements first:

    9.1 Please send samples first and we will conduct samples testing to determine the best finishing and polishing process.

    9.2 Evaluate the quantity of your product components and workpieces that need to be processed every day? What surface quality is required?

    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 tumbling 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 deburring 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 tumbling 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 deburring machine be used in?
  • Tumbling 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 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 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. 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.
  • 16. What surface treatments can the tumbling deburring machine perform?
  • 16.1 Deburring, deflashing, chamfering. Defects caused during workpiece processing that may cause harm to users can be automatically removed in batches.

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

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

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

  • 17．What are the tumbling media suitable for tumbling deburring machines?
  • 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 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.

  • 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.

  • 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?

    If you need some special electrical specifications, such as 220V-480V, 50-60Hz, you need to confirm with us in advance. These specifications need to be customized.

  • 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. The grinding and polishing time of a machine lined with PU should not exceed 30 minutes at a time to avoid high temperature damage to the lining.

The price of rough finishing media is also ranges from a few to more than ten dollars per kilogram. Generally, the machine can be used for more than a few years. It can also be used for several months to several years, and some polishing media like porcelain media, high-density porcelain media,etc. These tumbler media’s losses are smaller and can generally last for several years. Although stainless steel media are expensive to purchase at one time, they have almost no wear and can be used for a very long time.
  • 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.
What is vibratory tub finishing machine?

About Vibratory Tub Finishing Machine

        Let me ask a question first: If you have some parts with a longer appearance, such as a length of more than 500mm, can our existing finishing machines be used? The answer is no. The length of the workpiece processed by the centrifugal barrel or disc polishing machine generally cannot exceed 300mm. Although the length of the barrel tumbling finishing machine can exceed 500mm, it is not suitable for polishing because of its low efficiency. Rapid finishing and polishing in large quantities and with high efficiency are not it’s features. Although the current vibratory bowl finishing machines are relatively versatile, they are unable to handle some workpieces that are too long, because the channel width inside the machine’s working bowl generally does not exceed 500mm. So if you want to polish and deburr this type of workpiece, you need to use a long-chamber vibratory finishing machine. The working chamber of this polishing equipment is a long rectangular tub. The length of the customized tub can reach 2-4 meters. It is a special polishing machine specially suitable for polishing extra-long parts.
The heavy-duty designed work tub can handle large product workpieces, but for some products that cannot collide with each other, such as large impellers, automobile aluminum alloy wheels, etc., some dividers can also be designed and installed inside the tub to form separate chamber, each product is finished and polished in an independent working chamber, without causing surface damage caused by collision of workpieces with each other.
This model is also very suitable for finishing and polishing some large products such as marble tiles, engine casings, and engine crankshafts.
ShineTec provides universal standard tub-shaped vibratory finishing machines, and can also customize models according to the length and width of your workpieces. The working volume can range from 15L to 3000L, making it the best equipment for finishing and polishing ultra-long and ultra-wide parts.

Frequently asked questions about rectangular tub finishing machines:

  • 1．What is vibratory tub finishing machine?
  • The vibratory tub finishing machine is a polishing machine that uses vibration to deburring, descaling, cleaning, degreasing, deflashing and polish the surface of product parts and workpieces.
    It can be used to polish large and irregular workpieces with complex shapes. To avoid collisions between workpieces, divider can be installed inside the tub to allow each product of the same batch to be processed in a separate work chamber. The workpiece materials processed can be metals, alloys, ceramics, plastics, etc. If you have some large products that need to be finished and polished, then this rectangular tub finishing and polishing machine is a good choice.

  • 2. Can you tell me how a vibratory tub finishing machine works?
  • The working principle of the vibratory tub finishing machine is similar with othervibratory bowl finishing machines . When machine working, you need to put the workpiece, abrasive media, appropriate amount of finishing liquid and water into the machine. After the machine is started, the abrasive media and the workpiece will roll together longitudinally. The abrasive media will rub on the surface of the workpiece, which can remove burrs and oxidation layer on the surface of the workpiece. The time of the entire grinding process is determined according to the condition of the workpiece surface. The longer the burr or the thicker the oxide scale, the longer it takes. After finishing is completed, you will get a batch of products with the same surface grinding effect.
  • 3．What device and abrasive media are required for the polishing process of ShineTec vibratory tub finishing machine?

  • 3.1 Tub finisher. The machine consists of a rectangular working tub, vibration motor, electrical control box and other mechanical accessories.
    Working chamber. The workpiece, tumbling media, finishing compound, and water are put into the tub together, and then a series of surface treatments are performed, such as deburring, descaling, degreasing, chamfering, cleaning, polishing and brightening. These operations can be completed in the same batch .The tub is also lined with wear-resistant PU glue to prevent the workpiece from being damaged by the machine and abrasive wear on the iron plate inside the tub body of the machine.
    Vibration motor. The vibration motor is installed at the bottom of the working tub or at both ends of the tub. If it is at the bottom, only one motor is needed. If it is installed at both ends, two identical motors are needed.
    Water and liquid filling system. The grinding liquid and water are pumped into the working tub by a pump. The finishing liquid can be used to soften the surface oxide layer and speed up the grinding efficiency. It also has the function of cleaning oil stains under the combined action of clean water.
    Electrical control box. You can use the switch to control the machine to adjust the tumbling speed and vibration frequency of the machine. It also has overcurrent and overvoltage protection to prevent the motor from overloading.

    3.2 Ceramic media. The ceramic media generally used for deburring is called a deburring media. It is the main material involved in the deburring process. Because of the different content and grit size of the corundum sand contained in it, the deburring media are divided into heavy cutting force, medium cutting force and light cutting force. By rubbing the surface of the workpiece, the burrs and scale are removed.

    3.3 Water. Water plays several roles in the vibratory finishing process. First of all, water can lubricate and buffer between the workpiece and the abrasive media, so that the surface of the workpiece will not be damaged by impact. In addition, it can also cool down the machine. If there is no water involved in the grinding process, just dry finishing will cause the work tub to be damaged. The temperature becomes very high, which can easily damage the PU lining, while also preventing dust pollution. Finally, it can also wash away abrasive debris, workpiece burrs, oxide scale and other impurities produced after finishing.

    3.4 Polishing liquid. Polishing liquid helps speed up the finishing and cutting process. It can also prevent metal product workpieces from being corroded after contact with water. After polishing with compound liquid, the surface of the product can become more shiny.

  • 4．Are there other different names for vibratory tub finishing machines?
  • There are many different names. For example, rectangular tub finisher, tub tumblers, linear vibratory finishing machines, tub polishing machines, tub deburring machines, etc.
  • 5. What finishing and polishing processes can the vibratory tub finishing machine handle?
  • 5.1 Deburring. Burrs on the surface of product parts can be removed through the deburring process. We all know that burrs and flash can cause harm to users. After this process, the product becomes safe and easy to use.

    5.2 Smoothing and polishing. After smoothing and polishing process, the surface of the product will become brighter and the gloss will be further improved. If used with special polishing media and compound, the product will become dazzling and shiny. This is called brightening treatment.

    5.3 Degreasing and decontaminating. After the product is machined, a layer of sludge and dirt on the surface is difficult to clean. Ordinary manual cleaning is too inefficient and difficult to remove. The tub-shaped vibrating finishing machine can quickly clean the oil stains on the internal and external surfaces, dead corners, and holes in large quantities. It is the best automatic cleaning, degreasing and decontaminating process.

    5.4 Deflashing. Burrs, flashes are also annoying defects on the surface of workpieces. It is a quality problem that must be eliminated. A vibratory tub finisher can also achieve this purpose.

    5.5 Descaing. The tub polishing machine can also easily remove the oxide scale on the surface of the workpiece.

  • 6．What is the difference between the vibratory tub finishing machine and other finishing machines?
  • The first is that the length of the workpiece finished can be extremely long, such as more than 1 meter.
    Secondly, the working tub of the machine is open and unsealed. Compared with centrifugal polishers and barrel polishers, this structure allows users to observe the surface condition of the product at any time during the finishing process and evaluate whether it meets the predetermined standards.
    Furthermore, for some special large product components, such as aluminum alloy wheels, turbine blades, marble and other products that are not allowed to collide with each other, the working chamber can be separated and each product can be finished separately.
    It can be seen that the tub-shaped vibratory finisher is a finishing and polishing equipment with unique and specialized purposes.

  • 11. What routine maintenance can extend the service life of the vibratory tub finishing machine?
  • Listed below are things you need to pay attention to on a daily basis:

    11.1 Regularly check the mixing ratio of abrasive media, water, and workpieces in the machine.
    Because the abrasive will wear out after long-term use, the working tub also needs to maintain an appropriate amount of water to lubricate and buffer the grinding process. If the abrasive or water is insufficient, it will need to be added. Do not keep very few tumbling media in the machine to save on abrasive costs. Too small abrasive media ratio will increase grinding and polishing time and damage the surface quality of the workpiece.

    11.2 Check the condition of the machine before starting it every time. Make sure the machine is in good operating condition.

    11.3 Regular maintenance. In addition to some visual inspections, such as damage to PU lining and fractures of accessories, it is also necessary to pay attention to the condition of some fasteners, the aging of transmission components, and the lubrication of vibration motors.
    Good usage habits can ensure a longer service life of the rectangular tub vibrating polishing machine.
  • 12．What is the difference between the vibratory tub finishing machine and other vibrating finishing machines?
  • The working chamber of other vibratory polishing machines are bowl, but some workpieces are not suitable for finishing and polishing in annular containers.
    The tub-type vibrating finishing machine is the best choice for some large and long workpieces.
  • 13. What is the difference between the surface quality of vibratory tub finishing machine and manual finishing?
  • The difference between these two finishing and polishing methods is huge.
    The use of a vibratory tub finisher can ensure that the workpiece is always in a continuous finishing and polishing process, in which the cutting force is consistent and uniform, and the surface condition of the workpiece can be observed at any time to decide whether to stop finishing.
    The strength of manual finishing and polishing is inconsistent, and the finishing quality of the surface depends on the proficiency and skill of the worker. Therefore, the surface quality after grinding is uneven. If the workers’ skills are not up to standard, a lot of scrapped products may be produced, which will greatly increase the processing cost.
  • 14. What are the tub capacity specifications of the vibratory tub finishing machine?
  • The working volume can be from 15 liters to about 3000 liters. There are many different volume specifications to choose from.

  • 2. What equipment or materials are used to complete the vibratory deburring process?
  • The vibratory deburring process is mainly completed by the following equipment and materials:

    2.1 Vibrating deburring machine.
    The vibrating deburring machine is mainly composed of a vibration motor, a vibration working bowl, springs, and an electrical control box. These components are combined to achieve automatic deburring.

    2.2 Water.
    Vibrating deburring mainly uses wet finishing, so an appropriate amount of water needs to be used during the grinding process. It can buffer the collision between the deburring media and the workpiece, and can also clean the sludge on the surface of the workpiece. It is an indispensable part of the grinding process.

    2.3 Tumbling deburring media.
    The deburring media and workpiece are mixed together and put into the working bowl of the vibratory deburring machine. The deburring media contains corundum sand with cutting force, which can deburr the surface of product parts. The intensity of deburring depends on the content of corundum sand contained in the deburring media.

    2.4 Chemical deburring liquid.
    deburring liquid is also poured together with the media and workpiece in the work bowl. There are different types of deburring compound, such as liquid and paste, and some also have anti-corrosion and anti-rust effects.

  • 3．Can you tell me how the ShineTec vibratory deburring machine deburrs?

    It also depends on the size of the workpiece. The smaller the workpiece, the greater the quantity that can be processed at one time.

  • 10. What are the power requirements for a vibratory deburring machine?
  • Required industrial power: 380V/3-phase/50Hz. If you want to use it on household power supply, you need to customize a 220/single-phase motor. Because the exciting force of civil electric motors is relatively small, the working volume of the machine does not exceed 100L.
  • 11. What deburring media are mainly used in vibratory deburring machines?
  • The effect of deburring depends on the selection of the correct and suitable deburring media. The higher the abrasive sand powder content and the larger the grit size, the cutting force will increase accordingly, but the wear resistance will decrease. The smaller the deburring media, the smoother surface after deburring will be better than the larger tumbling media.
    The types of deburring media are as follows:

    11.1 ceramic deburring media. There are different deburring strengths such as heavy cutting, medium cutting and light cutting. Heavy cutting tumbling media can grind and deburr workpieces made of harder materials, such as iron, titanium alloys, hard plastics, ceramic products, etc. Medium cutting and light cutting tumbling media can finish precision parts such as stainless steel and alloy steel.

    11.2 plastic media. Also called resin deburring media, also known as polyester media. Usually used for precision finishing, deburring and polishing workpieces. Especially suitable for soft metal workpieces, such as aluminum alloy, zinc alloy, copper, etc. If ceramic deburring media is used to deburring these materials, scratches, pitting, and color dissipation will occur.

    11.3 stainless steel media. Stainless steel media are mainly used to improve the gloss and brightness of metal workpiece surfaces. It can also be used to polish some fine burrs on the surface of certain plastic or ceramic products.

    11.4 Natural bio-degradable media. If you are looking for an abrasive media that has the ability to gently and slightly deburr, then plant-based organic abrasives like walnut shells, corn cobs, etc. are a good choice. This kind of abrasive media can simulate the polishing effect of a cloth wheel. Through long-term finishing under slight cutting force, the surface of the workpiece can achieve an effect close to mirror polishing, so many people also call it mirror polishing media.
    This kind of abrasive can also be used as a drying media for surface drying after grinding and polishing of products. It also has the function of absorbing oil stains on the surface of the workpiece. It is a safe and environmentally friendly bioabrasive.
  • 12. What routine maintenance can extend the service life of the vibratory deburring machine?
  • For example, is the vibration motor lubricated regularly every month? Check whether the PU lining of the working bowl is damaged? Is the discharge port filter blocked by sludge? Is the vibration spring on the base of the machine broken?

    Vibrating deburring machine base spring
  • 13. How to choose the correct deburring media to match the vibratory deburring machine?
  • Tumbling deburring media selection plays a key role in the process of deburring. The abrasive sand in the tumbling media plays a role in finishing and polishing burrs on the workpiece.
    So how to choose the correct finishing media when deburring? There are currently four main categories of mass finishing media. Commonly used materials include brown corundum ceramic media, plastic deburring media, stainless steel polishing media and Natural bio-degradable abrasive media.
    These abrasive media have different cutting forces and different specifications and shapes, such as triangle, sphere, cylinder, three-star, cone, pyramid, wedge, etc.
    In order to fully reach the workpiece with complex shape during deburring, the upper shape can be made into a chamfered shape.
    Also consider whether the deburring media will clog holes and crevices in the workpiece. Generally, we will propose a selection plan for deburring machines and finishing media based on providing process samples testing.
    What are the best deburring machines and process solution and methods for deburring? Only after sufficient process testing and comprehensive consideration of surface effects and processing costs is the best solution.

  • 5．What does the guide angle of the eccentric weight on the motor mean?
  • The angle formed by the eccentric weights (commonly known as hammers) at the upper and lower ends of the motor is called the guide angle. The factory default angle is 90 degrees at right angles to each other. This angle causes the polishing media and workpiece to tumble from the outside to the inside of the vibrating polishing machine and rotate clockwise. If you need to adjust the vibration and rotation directions, the two included angles can be adjusted to 70 degrees or 120 degrees.
    The adjustment of eccentric weight of the vibration motor has two functions:
    ⑴ Adjustment of the excitation force: Remove the tightening bolts of the eccentric weight and adjust the excitation force by increasing or decreasing the number of eccentric weights;
    ⑵ Adjustment of the angle between the upper and lower eccentric weights: the upper eccentric weight is a fixed block and the lower eccentric weight is an adjustable block, both of which are pressed on the motor shaft using fastening bolts. There are reference lines engraved on both ends of the rotating shaft. The outer surface of the lower weight is equipped with a scale indicating the rotation angle. Loosen the pressing bolt of the lower eccentric weight and rotate the lower eccentric weight so that the angle scale mark on the lower eccentric weight is aligned with the reference mark of the rotating shaft line, adjust to the required angle, and tighten the lower eccentric weight holding bolt; if you need to adjust the angle of the upper eccentric block, you can also adjust it according to the corresponding method.

  • 2. What are the types of vibratory finishing machines?
  • ShineTec provides various types of vibratory finishing machines, which correspond to different product polishing needs.

    ❖ U-shaped vibratory finishing machine without separator.

    U-shaped vibratory finishing machine, the shape of the working bowl is a design similar to the letter “U”, and the inner wall of the upper opening of the bowl is straight, so it is also called a straight-wall vibratory finishing machine. Because there is no discharge separating screen, the size of the machine can be made smaller, and the minimum capacity can start from 30L. However, after the workpiece is polished, it needs to be picked up manually or mixed with abrasives media and discharged from the machine discharge port.

    ❖ U-shaped vibratory finishing machine with separator .

    There is a discharge port separator installed inside the working bowl of the machine that can automatically screen workpieces and tumbling media, so the minimum capacity of the machine needs to be from 100L. After the polishing task is completed, the workpieces can be automatically screened and output from the separating port. There is no need to manually grab each piece from the machine, which greatly improves the separation efficiency of the workpieces and abrasive media after batch polishing and reduces the time required and intensity of work.

    ❖ Arc-shaped vibratory finishing machine without separator.

    The arc-shaped vibrating finishing machine is also called a curved wall finishing machine because the inner wall of the working bowl is a curved arc design. Such a structure will generate greater pressure during the finishing and polishing process, which can improve the finishing efficiency of the machine in a relatively short period of time. It is especially suitable for products that require spherical tumbling media for bright polishing.

    ❖ Arc-shaped vibratory finishing machine with separator.

    Like the U-shaped machine, its working towl is equipped with a discharge port separating device that can automatically separate the workpiece and the tumbling media. Improve the screening efficiency of workpieces and reduce labor intensity.

    ❖ Tub-shaped linear vibratory finishing machine.

    It is suitable for surface finishing and polishing of large or extra-long parts. The vibration deviation generated by the vibration motor is used to cause the workpiece and the tumbling media to produce a two-dimensional movement trajectory, so that the workpiece and the finishing media grind each other in the working bowl. Achieve surface gloss effect.

    ❖ Continuous orbital vibratory finishing machine.

    By installing a spiral tunnel structure in the working bowl of the machine, a one-way motion trajectory is achieved for the workpiece to enter from the feed port and exit from the discharge port during the polishing process.
    The polishing time of a single workpiece can be controlled to avoid collision between workpieces.

    ShineTec's continuous tunnel bowl vibratory finisher


    ❖Vibrating dryer.

    Same as the vibrating finishing machine, the excitation force is generated by the vibration motor, which drives the drying media and the workpiece in the working bowl to produce a spiral three-dimensional movement. The media and the workpiece rub against each other, thereby achieving the effect of dehydration and drying of the workpiece. A hot air circulation device can also be installed to speed up the drying process.
    All vibrating finishing machines can be equipped with cylinder flaps for separator and silencer cover accessories to improve work efficiency and reduce work noise.

  • 8. What are the common problems in the operation of vibratory finishing machines?
  • Generally you will encounter two problems during the operation of the machine. One is that the tumbling direction of the materials is wrong; the other is that the rotation direction of the abrasive media is wrong.
    If the operation is normal, the tumbling direction of the abrasive and workpiece is from the outside of the working bowl to the central cylinder. The material rotates in a clockwise direction.
    If you find that the rolling direction is wrong, first check whether the two eccentric weights on the bottom of vibration motor are at an angle of 90 degrees to each other. If not, please adjust the angle of the eccentric weights.
    If the problem still cannot be solved after adjusting the angle of the eccentric weight, please check the power cord of the control box and exchange the live wire and neutral wire in the three-phase line.
    If the abrasive media movement direction in the machine is not clockwise, first check whether the abrasive load is too much. Please confirm that the ratio of abrasive to the total volume of the working bowl does not exceed 2/3. Also check again that the angle between the motor eccentric weights is 75 degrees or 120 degrees.
  • 9. What kind of power supply does a vibratory finishing machine require?
  • Our vibratory finishing machine requires 3 phases, 380V, 50Hz. If there are different power usage environments, please confirm with us in advance before ordering the machine.

The inner wall of the bowl is lined with high-strength wear-resistant elastomer polyurethane (PU) to protect your polished parts and prevent wear of the inner wall of the machine.

    10.2 Separating screen.
    There are two types of built-in separating screens. One is made of PU casting and is suitable for screening workpieces of regular sizes. The other is made of stainless steel mesh, which is suitable for relatively small product parts.

    10.3 Vibrating motor.
    The vibrating motor is the power source of the vibratory finishing machine and is also a very important machine component. The motor with the eccentric weight generates excitation force, which drives the abrasive media and the workpiece in the machine working bowl to produce spiral three-dimensional motion to achieve surface finishing effects such as deburring, descaling, chamfering, contaminating and derusting and brightening .

    10.4 Spring.
    A ring of spring supports at the bottom of the working bowl suspends the bowl body on the base. The motor drives the working bowl to produce up and down reciprocating vibrations.

    10.5 Acoustic Lid.
    The machine can also be equipped with an optional acoustic lid to reduce noise during operation. However, this is not a necessary accessory, because the noise generated by the vibrating finishing machine during operation is bearable for the human body.
    In addition, the acoustic lid can also prevent the foam produced by adding excessive polishing liquid from splashing and staining the surrounding ground environment.

  • 10．What are the different types of mass finishing machine?
  • There are four different basic types of mass finishing polishers. They are vibratory (also called vibrating) finishing machines, centrifugal disc finishing machines, centrifugal barrel finishing machines, and barrel tumbling finishing machines.
    In these models, the machine drives the workpiece to tumble and rotate together with the abrasive media, and the abrasive frictionally cuts on the surface of the workpiece to achieve the purpose of polishing. This process is also called mass finishing.
    Vibratory finishing is the most commonly used polishing method. Driven by the excitation force of the motor, the abrasive and the workpiece perform a three-dimensional spiral tumbling motion in the machine. The surface of the workpiece is cut by the finishing media to complete the polishing process.
  • 11．Are there different types of abrasive media?
  • Yes, there are different types of tumbling finishing media suitable for different process requirements.
    The specific parts are different, and the applicable abrasives media are also different.
    Tumbling media include ceramic media, plastic/resin media, stainless steel media, bio-degradable media and other varieties.
    Each abrasive media has different shapes, specifications, cutting forces and other indicators.
    You can choose different tumbling media according to your different needs.

  • 15．How long does mass finishing usually take?
  • Polishing time varies depending on the machine model.
    It can range from 10 minutes to several hours depending on the workpiece being processed.
    Generally speaking, the efficiency of centrifugal disc finisher > centrifugal barrel finisher > vibratory finisher > barrel tumbling finisher.
  • 16. What is the function of the polishing liquid added in mass finishing?
  • Polishing compound play an important role in the polishing process.
    It can help soften the surface of the workpiece, clean oil stains during friction cutting, protect the product surface, prevent surface oxidation, reduce roughness, and improve brightness.
  • 17．What are the best finishing media for mass finishing machine?
  • Different workpieces and machine models are suitable for different finishing media. So there is no such thing as the best abrasive.
    Of course, the quality of the abrasive media will definitely differ. High-quality tumbling media are definitely better than low-quality and low-priced ones.
    Inferior tumbling media will damage the surface of your workpiece and increase your polishing time.
    Poor tumbling finishing media are produced from recycled corundum sand, which has poor wear resistance and high wear. The sludge generated in the same processing time will greatly increase, and the product service life is short. Although the initial purchase price is cheap, it is not durable and increases the use of the media and sludge disposal costs.
    Commonly used abrasive media with cutting force include ceramic deburring media and resin media.

    17.1 Ceramic media.
    Ceramic media are used for deburring and finishing hard parts.
    According to different cutting forces, they can be divided into different product types.
    The tumbling media with cutting force is generally ceramic finishing media, polishing and brightening is porcelain polishing media.

    17.2 Resin media.
    Resin media is also called plastic media, polyester media, suitable for deburring and finishing of soft metal or alloy products.
    For example, workpieces made of aluminum alloy, magnesium alloy and other materials.
  • 18. What should I pay attention to when operating the mass finisher?
  • Routine maintenance of the machine is crucial to its service life.
    Generally, the following steps should be checked regularly to ensure that the machine is operating normally.

    18.1 Amount of tumbling media used.
    The proper abrasive media must always be kept in the machine. The volume of the tumbling media in the machine is generally more than 2/3 of the overall capacity of the working chamber. Do not put a small amount of tumbling finishing media in the machine just to save costs.
    Too little finishing media will damage the workpiece, slow down the grinding process, and reduce polishing efficiency.

    18.2 Check the drain outlet regularly.
    Debris or sludge from the finishing process can sometimes clog drains. Therefore, it is necessary to regularly check whether the drainage outlet is open or not.
    If it is blocked and not dealt with in time, the machine will be flooded with water.

    18.3 Inspection of PU lining.
    The PU lining protects the workpiece and prevents the finishing media from directly contacting the inner wall of the chamber and cutting the machine working chamber.
    Therefore you should always check the wear of the PU lining rubber. Once damaged, the machine should be re-lined promptly.

    18.4 Do not use the machine under overload conditions.
    Loading excessive workpieces into the machine can damage the machine. At the same time, self-damage of workpieces is caused by the collision between workpieces.
    Therefore, it is necessary to read the manual carefully and understand the maximum working load before starting to use the new machine.
