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

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

6. Final summary
  • In this case, we demonstrate a process for surface chamfering and deburring of stainless steel laser-cut metal sheet parts using resin finishing media and corn cob drying media.
  • This process is also suitable for surface polishing of sheet metal parts such as carbon steel and aluminum alloys.

The production and manufacturing process of vibratory finishing machines

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

Vibratory finishing machine production process
  • 1. Blanking

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

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

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

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

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

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

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

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

What is the automatic mass finishing system?

About Automatic Mass Finishing System

  • 1. What is the automatic mass finishing system?
  • The automatic mass finishing system, also called the automatic finishing and polishing production line, is a mechanical equipment for finishing and polishing that uses modern transmission and electrical control technology from a series of processes such as feeding, deburring, polishing, cleaning, separating, drying, and discharging, combined into a complete set of integrated assembly lines. The main purpose is to reduce manual work, improve production efficiency, reduce production costs, and ensure the surface treatment quality of product workpieces.
  • 2. Why do I need to use the automatic mass finishing system?
  • For some manufacturers who need to carry out a large amount of daily finishing and polishing treatments such as deburring, descaling, deflashing, derusting degreasing, cleaning, polishing and brightening, etc., they are generally equipped with multiple finishing and polishing machines and Complete with auxiliary equipment. For example, some machines are used for rough finishing, some machines are used for fine finishing, and some machines are used for polishing brightness. The flow of product workpieces between different machines requires loading, unloading, and screening, cleaning, transportation, drying and other different processes, each process requires personnel to operate. Medium and large operating capacitibility of mass finishing machines usually process hundreds or even thousands of kilograms every time. The labor intensity of loading and unloading so many parts into different machines is huge. Moreover, manual loading and unloading takes at least half an hour at a time. Therefore, using independent machines to perform polishing operations is a time-consuming and laborious task that requires a lot of labor costs and has low production efficiency.

    In order to reduce labor intensity and improve work efficiency, we can design and connect the finishing and polishing machines at different process points using auxiliary facilities such as mechanical hydraulic lifting, conveying transmission, online cleaning, and online separating, so that the product workpiece can be completely processed from feeding to finished product discharging. Realize online operation, reduce manual intervention, and realize automated mass finishing functions.
    Using these modern mechanical and electrical control technologies, you can turn your mass finishing equipment into a fully automatic CNC finishing machine, greatly improving equipment utilization, reducing labor costs, increasing finishing and polishing efficiency, and creating greater profits for your factory. If you don’t know where to find this kind of automated mass finishing system, we can analyze the calculation data and propose a solution based on your actual production situation.

  • 3. What systems does the automatic automatic mass finishing system consist of?
  • 3.1 Automatic loading system. The first machine that starts the finishing process will be equipped with a material lifting hopper. Workers only need to put the abrasive media or product workpieces before rough finishing into the hopper and control the lifting of the hopper to put the materials into the machine.

    3.2 Tumbling finishing and polishing machines. The finishing machine is the main component of the automatic finishing and polishing production line. This part of the system can be vibratory finishing machine, or centrifugal disc finishing machine, or centrifugal barrl finishing machine, even Rotary tumbling barrel finishing machine.

    3.3 Auxiliary discharging device. Every finishing machine needs to unload after finishing is completed. When the vibrating finishing machine discharges materials, it is necessary to configure a hydraulic or pneumatic turning plate inside the machine to connect the bottom of the machine’s working chamber and the discharge port separating screen. When the material needs to be discharged, press the control button to turn the flap up and close the separating screen, so that the workpiece can automatically climb from the groove to the separating screen and output the workpiece. When the centrifugal disc finishing machine discharges materials, it is necessary to use the hydraulic struts at the bottom of the barrel of the machine to hold up the barrel and turn it over, so that the abrasive media and the workpiece can be poured into the built-in vibrating separator for discharge. Centrifugal barrel finishing machines are rarely integrated into automatic production lines. There is no need to equip additional special equipment when discharging materials. You only need to turn the barrel opening downwards to pour out the materials.

    3.4 Separating device. Each machine is equipped with a separating screen to automatically separate workpieces and abrasives after discharging. The vibrating polishing machine is built into the working bowl, and the other three machines require additional special separating screens.

    3.5 Transmission system. Using mesh belts and rollers, the separated workpieces are transferred to the machine for the next process. Some transfer systems are also equipped with a flushing function to clean the workpiece again during the transfer process.

    3.6 Water-liquid circulation system. Using the sewage treatment system, the flushed wastewater containing polishing compound is recycled and filtered and pumped into the machine again for use.

    3.7 Drying system. There are two ways, one is to transport the cleaned workpieces into a vibrating dryer, the other is to equip an online pass-through drying box to dry the workpieces on the conveyor belt.

  • 4. What types of automatic automatic mass finishing system does ShineTec have?
  • According to different finishing machines, there are four types of automatic mass finishing system: vibratory finishing system, centrifugal disc finishing system, centrifugal barrel finishing system, and barrel tumbling finishing system. The first two models are most commonly integrated into production lines.
  • 5. Where can the automatic mass finishing system be used?
  • All factories that currently need to use multiple finishing machines for surface treatment processes such as deburring and descaling can consider configuring automated mass finishing system.
    Here are some questions you can pre-evaluate:

    How do your product workpieces flow between polishing machines in different processes?

    How long does it take to transfer between each different process?

    How did you add water and polish compound?

    How do you separate tumbling media and workpieces?

    If an automatic assembly line is used for circulation, how many finishing batches can be added?

    On this basis, after comparing the investment returns, you can consider whether to invest in this kind of automated mass finishing production line.

  • 6. How to choose a suitable automatic mass finishing system?
  • It is indeed a challenge to choose an automated mass finishing system that is most suitable for your product finishing and polishing process.

    The tumbling barrel finishing automated production line is the slowest type of work efficiency, but it can achieve the most beautiful results for the surface polish quality of the product, especially for surface finish and gloss. In terms of brightness, it can have an effect close to mirror polishing.

    Automatic vibratory (vibrating) finishing system are the most widely used type. Its working efficiency is much higher than that of the barrel finishing type. Because of the built-in separating screen, the material can be discharged directly from the working chamber, and there is no need to add a hydraulic lifting device to flip the working barrel. Therefore, the manufacturing cost of the entire production line can be lower than that of the disc finishing type and centrifugal barrel finishing type.

    Automatic centrifugal disc finishing system are also widely used. It has the highest working efficiency and can quickly achieve finishing and polishing effects. Since this type of machine needs to use a hydraulic lifting device to pour the materials in the barrel into a separately configured screen when discharging materials, the overall cost of the assembly line is higher.

    Automatic centrifugal barrel finishing system is suitable for surface treatment of precision parts. Because the processing capacity is small, it is not necessary to integrate into the assembly line, so there are few application areas.
    If you don’t know which type of mass finishing system your product is suitable for, please contact us. ShineTec will conduct professional evaluation analysis and calculations for you and provide you with the most cost-effective solution.
  • 7. How to use the automatic mass finishing system?
  • The automatic mass finishing system provided by ShineTec is a highly integrated complete set of finishing and polishing equipment. Using pneumatic, hydraulic, and CNC technologies, multiple independent polishing machines are connected together through a set workflow combination to become a fully automatic finishing and polishing machine. The operator only needs to press each function button on the console to automatically complete the feeding, deburring, descaling, deflashing, degreasing, finishing, polishing, cleaning, drying, discharging and other processes. It is an easy-to-operate, powerful automated polishing assembly line.
  • 8. What kind of tumbling media are needed for the automatic mass finishing system?
  • Just like when the machine is used alone, it depends on what kind of Tumbling Media is used Depending on what kind of workpiece needs to be finished. ShineTec can provide abrasive media for three purposes: rough finishing, fine finishing and polishing:

    8.1 Tumbling media for rough finishing, mainly include ceramic deburring media, Resin media , divided into heavy cutting force, medium cutting force and light cutting force.

    8.2 Tumbling media for fine finishing, white Corundum finishing media, chrome corundum finishing media, 3P finishing media, etc., because the particle size of the micropowder contained in it is very fine, some of which are nearly 2000-3000 mesh, it can continuously perform micro-cutting on the surface of the workpiece to form a more delicate surface roughness.

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

    If you don’t know which is the best polishing media, please contact us and ShineTec can provide you with professional suggestions and answers.

  • 9. How long does it take to complete the polishing process on the automatic mass finishing system?
  • Now, the time it takes to polish a batch of workpieces using an automatic mass finishing system is definitely much shorter than manually operating several independent finishing machines.

    The length of processing time depends on which type of production line you have applied. Generally speaking, the centrifugal disc type and barrel type can complete the grinding work within 30 minutes. With discharging, cleaning and other processes, the entire process can be completed in as fast as 1 hour from feeding to discharging. The vibration-type unit may take 2 hours to complete the entire process, while the tumbling barrel-type unit may take longer and may take several hours to complete the finishing work.

  • 10. What is the daily maintenance of the automatic mass finishing system?
  • Regular daily maintenance can keep your polishing automatic production line in the best working condition, extend the service life of the machine, and reduce maintenance expenses.

    10.1 Inspection of mechanical components. The vibrating finishing automatic production line needs to add lubricating grease to the vibration motor used in the machine every month; the disc automatic finishing production line needs to check whether the gap between the barrel and the chassis is normal, whether there is a chuck, and whether the transmission belt is Relaxation; for a centrifugal barrel automatic polishing production line, it is necessary to check whether the transmission chain, sprocket or timing belt is worn, whether there is any abnormal noise during operation, and whether the barrel cover can be sealed; for a tumbling barrel-type automatic polishing production line, it is also necessary to check whether the transmission part is working Normal, there is no leakage after the cover is sealed. Some pneumatic or hydraulic devices on the production line also need to be checked for air and liquid leaks.

    10.2 Check the loading of abrasive media used. The loading of abrasive media in the machine should be checked before each start-up. Too much or too little usage will cause damage to the machine or product workpiece, affecting the efficiency of finishing and polishing.

    10.3 Water circulation system inspection. Check whether the water inlet, drainage, and quantitative filling of polishing compound are working properly. Pay special attention to whether the drainage pipe of the machine is blocked.

    10.4 PU lining examination. Check whether the PU or rubber lining of the machine is worn or damaged. If so, it needs to be replaced immediately.

    10.5 Don’t overdo it. Do not overload abrasive media and product workpieces into the machine. Generally, the total volume of materials does not exceed 70% of the total capacity of the machine. If stainless steel media need to be used in the machine, due to their large proportion, they are generally controlled within 50%.

  • 11. What is the price of the automatic mass finishing system?
  • Each automatic mass finishing system is a customized fully automatic finishing assembly system. We need to quote based on your actual use site, product processing capabilities, process requirements and other data. If you are looking for manufacturer of automated mass finishing system, please contact us, ShineTec will provide you with professional solutions.
What is the tumbling barrel deburring machine?

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.

    ShineTec's tumbling barre deburring machine
  • 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.

    6.3 Frequency conversion speed regulation function. A frequency converter is also installed in the electrical control box, which is suitable for adjusting the machine at different operating speeds.

  • 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.

    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 barrel 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 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. 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 barrel 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 barrel 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: ceramic deburring media, porcelain polishing media, high-density porcelain media, plastic media, white corundum polishing media, 3P precise polishing media, walnut shell mirror polishing media , corncob drying mediaWait.
    Improper selection of abrasives during the finishing process will affect grinding efficiency and may even cause damage to the workpiece.

About Rotary Barrel Tumbling Machine

  • 1．What is the rotary barrel tumbling machine?
  • Rotary Barrel Tumbling 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 rotary barrel tumbling 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 roraty barrel tumbling deburring and other deburring processes?

  • 2.1 Rotary barrel tumbling 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 rotary barrel tumbling 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 rotary barrel tumbling 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.

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.

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.

  • 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?

  • You must check the condition of the machine before each start-up to ensure that the machine is in good condition.
    Check whether the lining of the centrifuge barrel is damaged and whether the sealing cover is sealed and water-proof. Otherwise, the water in the barrel will be thrown out and splash inside the machine during the operation of the machine, causing safety hazards.
    Check whether there is any noise during the operation of the machine. These noises may be caused by damaged bearings, sprockets, transmission chains and other components. Check to see if they are properly lubricated.
    Check the machine’s transmission chain every two weeks. Is the tightness appropriate? Are the tightening bolts normal?

  • 10．What kind of power supply does the centrifugal barrel finishing machine use?
  • The applicable power supply for our universal centrifugal barrel finishing machine is 380V/3-phase/50Hz.
    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.
