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 centrifugal disc finishing machine?

Centrifugal Disc Finishing Machine

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

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

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

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

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

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

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

    unloading of centrifugal disc finisher
  • 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.

  • 6. What optional configurations are available for ShineTec’s centrifugal disc finishing machine?
  • 6.1 Wear-resistant bucket bottom gasket.

    6.2 Bucket electric tilt configuration.

    6.3 Quantitative automatic filling of clean water and polishing fluid.

    6.4 Built-in automatic separator.

  • 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?
  • Please confirm the following basic requirements first:

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

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

    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.

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

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

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

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

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