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.

    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%.

    ShineTec's automatic wastewater treatment system
  • 2. Why is wastewater treatment needed?
  • The finishing process of deburring and descaling requires the use of various abrasive media and Chemical Finishing Compound. Most abrasive media such as ceramic media, high alumina porcelain media, resin media and other materials will produce a large amount of sludge due to wear during the grinding process. This sludge is mixed with metal debris and other impurities that fall off the workpiece due to wear and tear. If not cleaned in time, the surface of the product will be worn. Therefore, during the finishing and polishing process, it is necessary to flush with water from time to time, and then flush with clean water. The waste water discharged from the drain outlet of tumbling finishing machine must be treated Environmentally friendly treatment and discharge directly.
    In addition, a large amount of clean water is used during the finishing process, and it is also mixed with chemical additives such as polishing compound. For environmental reasons, you cannot discharge this wastewater directly into the surrounding environment.
    This automatic sewage treatment system can solidify and dry sludge, recycle wastewater, and meet environmental protection requirements. It can well solve the problem of not knowing how to treat wastewater.

  • 3. Can the water treated by the automatic wastewater treatment system be reused?
  • Yes, the water treated by the automatic sewage treatment machine can be reused in the tumbling finishing machine.
  • 4. How does the automatic wastewater treatment system treat the sludge and sewage generated after finishing and polishing?
  • The wastewater discharged after finishing and polishing is introduced into the wastewater treatment tank of the automatic sewage treatment machine, which is also called a coagulation sedimentation tank. By adding some treatment agents to the water, usually called coagulants or coagulants, the particles that are difficult to settle in the water can aggregate with each other to form colloids, and then combine with other impurities in the water to form larger flocs. The large organic particles in the polishing liquid are adsorbed by the flocs, increase in volume and sink. The well-reacted wastewater is pumped into the filter press system for solid-liquid separation, forming mud cakes for solid waste treatment. The filtered water has been discharged up to standard and can be used for secondary use.

  • 3．Can you tell me how the deburring tumbler works?
  • In order to solve the problems of low efficiency, low quality and high labor cost of manual deburring, ShineTec’s deburring tumbler is an automatic deburring and polishing machine. The main operating principle is to combine special tumbler media with product workpieces, appropriate amounts of water and finishing compound. Mix them together in a certain proportion and put them into the working barrel of the deburring machine. Vibrating, centrifugal barrel high-speed rotating, centrifugal disc rotating, tumbling barrel rolling and other mechanical movements are used to tumble and rotate the finishing media and the workpiece together in the barrel, using the cutting force of the abrasive media surface, polish the burrs on the surface of the workpiece.
    Each movement method has its own advantages and disadvantages, and is suitable for different finishing and deburring needs. Vibratory deburring is the most common process method. If you need to process large quantities every day, such as workpieces of hundreds of kilograms or more, then choose a vibrating deburring machine. If you need to process some small precision parts, the quantity is within tens of kilograms, the centrifugal barrel deburring process is the most suitable method. If you are looking for the fastest deburring process, then centrifugal disc deburring is the fastest polishing method. If you want to find the cheapest, lowest cost deburring process, go for the barrel tumbling deburring method.

  • 4. What are the benefits with a deburring tumbler?
  • The main benefit is that this is a high-volume, high-efficiency automatic deburring process. details as follows:

    4.1 Compared with manual deburring, the efficiency can be improved dozens of times. Using some large-scale deburring machines, hundreds or even thousands of kilograms of material can be fed at one time, and all can be completed within dozens of minutes or hours. Such processing efficiency cannot be compared with manual deburring.

    4.2 The surface effect after deburring is uniform and controllable. The quality of manual deburring and polishing depends on the personal skill level of the worker. Some products may have clean burrs, while others may still have some residue. The surface quality of each product is different. Sometimes it may also cause product damage, resulting in a relatively high scrap rate.

    4.3 The running costs of deburring tumblers are extremely low. The one-time purchase cost of the machine starts from a few thousand dollars, and it can generally be used for many years. The choice of ordinary tumbler deburring media depends on the actual conditions of the product parts that need to be processed, and the price ranges from a few dollars per kilogram to more than ten dollars. Buying a few hundred kilograms at a time can usually take several months. The amount of polishing fluid is very small and the cost is almost negligible.
    Ordinary models can feed dozens of kilograms of workpieces at a time, and the deburring time for a batch is generally 30-60 minutes. The direct cost of finishing and polishing when evenly distributed to each product is minimal.
    On the other hand, the advantages of automatic deburring tumbler are 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.

    4.4 In addition to the automatic deburring function, ShineTec’s deburring tumbler can also perform surface treatment processes such as descaling, derusting, deflashing, smoothing, cleaning, chamfering, degreasing, decontaminating, and improvement of surface brightness. It features powerful functions and wide applicability. If you don’t know how to quickly deburr your product, we recommend you learn more about our fully automatic deburring tumbler.
  • 5. What types of deburring tumbler do ShineTec have?
  • According to different operating modes, our deburring tumblers are divided into the following four types:

    5.1 Vibratory Deburring Machine. It is a general-purpose deburring machine. The spiral vibration method is used to drive the deburring media and the workpiece to move together to achieve the vibration deburring effect.

    5.2 Centrifugal Barrel Deburring Machine. It is suitable for rapid deburring of precision parts and components. It is similar to the operation of a Ferris wheel. The motor drives the large centrifugal disk to rotate, allowing the four barrels on the disk to rotate at high speed, driving the deburring media and the workpiece to move together to achieve the centrifugal deburring effect.

    5.3 Centrifugal Disc Deburring Machine. It is the fastest deburring equipment. The chassis drives the barrel to rotate at high speed on the horizontal plane. The deburring media and workpiece also tumble and rotate in the barrel to achieve the disc deburring effect.

    5.4 Tumbling Barrel Deburring Machine. It is the simplest structure and the lowest cost deburring method. The barrel rolls around the central axis, and the deburring media in the barrel rolls together with the workpiece to achieve the tumbling deburring effect.

  • 6. What does dry and wet deburring mean?
  • Dry finishing is a deburring and polishing method that only adds finishing media, workpieces, polishing paste or polishing powder when the machine is running, and does not add water.
    Wet finishing is a deburring and polishing method that requires adding an appropriate amount of chemical liquid and water to the finishing media and workpiece when the machine is running.
    Wet finishing is the most widely used finishing and polishing process. For most common materials and general-purpose products, wet deburring is the most suitable method. With the assistance of water and liquid finishing compound, it can speed up the deburring process, reduce bumps, lower the machine operating temperature, and avoid dust producing, extending the service life of the machine.
    Dry finishing is mainly used in the polishing process of some products that cannot come into contact with water, such as the deburring process of some easily corroded metal products, wooden handicrafts, precision parts, and the drying process of products after wet finishing.

    12.3 Your product parts size. The workpiece within 300mm can be processed by all models, but the vibrating finisher is the most commonly used deburring equipment. For workpieces that are too long, a rectangular tub deburring machine is needed. Some small-sized precision parts require the use of a centrifugal barrel finisher. For workpieces within 100mm that need to be quickly deburred, a centrifugal disc finisher is the best choice. No afraid of deformation or bumping. Use a barrel tumbling finisher for thin workpieces within 300mm in length that are easy to adsorb to each other.

    12.3 Selection of deburring media. According to the effect of the sample, select the appropriate abrasive media, cutting strength, shape, and size.

    12.4 Durability of tumbling media. Different cutting strength, shape, and size determine the different wear resistance properties of abrasive media when used. Tumbling media with heavy cutting force have smaller wear resistance than media with light cutting force due to the large grit size of corundum sand contained. The larger the product, the longer it will last and the more wear-resistant it will be. There are also different shapes with different wear resistance. For example, shapes such as spheres and cylinders are more durable than triangles and tri-star shapes.

    12.5 Finishing time. The deburring efficiency of each model is different. You should choose the appropriate model based on your production shift schedule, product output, and batch processing time requirements for finishing and polishing.

    12.6 The working intensity. The bowl of the vibrating deburring machine is open, making it easy to load materials; the centrifugal disc type is similar and easy to load and unload; the centrifugal barrel type has a smaller working barrel and a smaller opening, so it takes more time to load and unload. The opening of the tumbling barrel is also small, and the loading and unloading of materials is relatively slow; the overall labor intensity and loading and unloading time are stronger than the centrifugal disc/barrel type.

  • 13．What tips can improve the deburring efficiency of deburring tumbler?
  • Some precautions during actual use can help improve the efficiency of the automatic deburring and polishing machine.

    13.1 Reasonable ratio of abrasive media to workpiece. The reasonable ratio of the two when loading and feeding is the key factor affecting the finishing and polishing efficiency. The most commonly used ratio is 3:1 abrasive to workpiece. Please refer to the table below to determine your usage:

    Abrasive media to workpiece volume ratio Typical application
    0 : 1 No tumbling media, self-finishing and polishing, such as some decorative stones for handicrafts.
    1 : 1 The same proportion of abrasive media and parts such as forgings, castings, etc., with very rough surfaces.
    2 : 1 Gentle finishing, allowing workpieces to collide with each other.
    3 : 1 Minimum ratio for finishing copper, aluminum, zinc and other non-ferrous metal workpieces. The workpieces may collide with each other, so the ratio is suitable for grinding and polishing ferrous metals.
    4 : 1 The ratio of non-ferrous metal workpieces with average efficiency. High polishing efficiency ratio for ferrous metal parts.
    5 : 1 More suitable for finishing non-ferrous metal parts. Workpieces rarely collide with each other.
    6 : 1 Suitable for finishing of non-ferrous metal products. Commonly used for pre-plating treatment with resin media and aluminum and zinc alloy workpieces.
    8 : 1 Suitable for finishing of non-ferrous metals or precision parts. Less surface roughness and smoothness.
    10:1~20:1 Better finishing quality. Suitable for irregular shapes or fragile workpieces.
    Maximizing No collision between workpieces. One machine polishes one part or each workpiece needs to be separated.


    13.2 Loading capacity. Too much or too little loading will affect the finishing efficiency of the machine. Please do not feed materials at 100% full load or less than 50%. Generally, the overall volume of the material after loading does not exceed 70% of the barrel volume, and the water surface does not exceed 80% of the barrel volume.

    13.3 Amount of finishing compound liquid. Too little dosage will definitely not play the role of the additive in accelerating grinding. Too much dosage will produce a large amount of foam, which will pollute the environment, and on the other hand, it will block the tumbling and rotating motion of the abrasive media and the workpiece, reducing the grinding efficiency.

    13.4 Suitable machine operating speed. This is a process that requires long-term experience accumulation. Polishing efficiency depends on the material and size of the tumbling media used, the amount of water and chemical finishing liquid added, and the running speed of the machine. Too little material input and high-speed machine operation speed will cause over-grinding of the product, affecting the overall size, accuracy or chamfering degree. Excessive material input and too low machine speed will cause insufficient movement of the workpiece inside the abrasive media, reduce cutting strength, and affect efficiency.

  • 14. How long does it take for a deburring tumbler to work?
  • It depends on the specifics of your product. Generally speaking, soft metals such as aluminum alloys and zinc alloys can achieve a satisfactory effect in less than an hour, while hard product workpieces such as stainless steel, titanium alloys, and cemented carbide may require Requires more than 2 hours of deburring time.
    In addition, the size of the machine used also affects the processing time. The bigger the machine, the less time it takes to grind.

About Tumbling Barrel Deburring Machine

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

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

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

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

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

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

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

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

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

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

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

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

    4.3 Automatic chamfering. Products can be chamfered quickly.

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

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

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

    On the other hand, the advantage of using a barrel tumbling deburring machine is even greater in terms of saving labor costs. As long as workers need to handle it when loading and unloading materials, the machine can be operated unattended, which greatly saves labor costs.

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

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

    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.

  • Rotary Barrel Tumbling 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 rotary barrel tumbling 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 rotary barrel tumbling 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 rotary barrel tumbling 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 rotary barrel tumbling 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.
