5. Additional instructions
  • The dental probe is made of stainless steel. After annealing, there is a thick oxide layer on the surface of the product, the color is black, and there will be slight burrs on the edge of the hole. It is necessary to remove the burrs, oxide scale, reduce the surface roughness, and further improve the brightness. Therefore, the finishing process combining rough deburring, descaling and fine finishing and mirror polishing is adopted. The polishing machine uses centrifugal barrel finisher with heavy cutting force angle cut cylinder ceramic tumbling media. The sharp angle of the ceramic deburring media can reach into the grooves, corners, and inner walls to achieve the effect of removing burrs and oxide layers.
    Fine finishing uses precision polishing media without cutting force straight cut cylinder high-density porcelain polishing media, which has a high density and has a polishing and brightening effect, which can further reduce the surface roughness.
    In order to improve the anti-rust performance of the product after water treatment, after fine finishing, use a centrifugal spin dryer to dehydrate and dry the moisture on the inner and outer product surfaces.
  • For mirror polishing, use walnut shell mirror polishing media and polishing paste to achieve a mirror-like surface effect.

6. Final summary
  • In this case study, we demonstrated the process of automated surface deburring and descaling of stainless steel probe used in the dental medical industry to achieve mirror polishing.

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 an automatic wastewater treatment system?

About Automatic Wastewater Treatment System

  • 1．What is an automatic wastewater treatment system?
  • The automatic wastewater treatment system is a small complete set of environmentally friendly treatment equipment that automatically recovers and treats sewage and sludge generated during the grinding, finishing and polishing process.
    You only need to connect the wastewater generated during the finishing and polishing process to the working tank of the automatic sewage treatment machine, and it will handle the rest. If your factory needs to continuously produce finishing, polishing, cleaning wastewater and waste liquid every day and you don’t know how to deal with it, ShineTec can provide you with this professional integrated complete set of sewage treatment equipment and machinery to solve your environmental discharge problems.

    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.

  • 5. Can an automatic wastewater treatment system reduce the amount of water used in the finishing process?
  • Yes, because the water treated by the automatic sewage treatment machine can be reused, which will greatly reduce the amount of water consumed by your factory in finishing and polishing processes. The recycled water can be recycled 3-5 times, which can save you a lot of water costs.
  • 6． How does the automatic wastewater treatment system reduce the cost of sludge treatment?
  • After the wastewater containing sludge is filtered by this sewage treatment system, the solid content of the mud cake can reach 50%-70%. The volume and weight are greatly compressed, and solid waste can be directly treated without the need for large-capacity sedimentation. The pool is handled by dedicated staff. The cost of sludge treatment can be greatly reduced.
  • 7. What are the benefits of using a wastewater treatment system?
  • 7.1 The disposal of large amounts of waste liquid generated during large-scale finishing and polishing processes is a very troublesome problem. It costs a lot to deal with it through a professional third-party recycling company. Configuring a large-capacity sedimentation tank yourself also requires a lot of capital and labor costs. Now you can invest in a set of small wastewater treatment equipment and machinery at one time. It perfectly solves the problem of environmental protection and is really a cost-effective solution.

    7.2 Recycling after sewage treatment can save you a lot of water costs and also bring you direct benefits.

    7.3 During the finishing and polishing process, a large amount of recycled water can be recycled to clean the workpiece to avoid debris and impurities during the finishing process from damaging the surface of the workpiece, causing problems such as pitting and scratches. It also improves the surface quality of the workpiece and avoids worries about using water. If the amount is too large, it will reduce the cleaning time during the grinding process and reduce the finishing efficiency or produce defective products.

    7.4 Easy to operate. The automatic sewage treatment machine provided by ShineTec is a set of fully automated water treatment equipment that is easy to operate and use. The flow of waste liquid between systems is all through pipelines, without manual handling and no complicated structure.

What is a centrifugal dryer?

About Centrifugal Dryer

  • 1．What is a centrifugal dryer?
  • Centrifugal dryer, also called centrifugal hot air dryer, industrial spin dryer and dehydrator, is a commonly used auxiliary equipment in the tumbling finishing and polishing industry.
    It uses a centrifugal disk to rotate at high speed to drive a stainless steel barrel to perform centrifugal motion to dry the water on the surface of the workpiece in the barrel. It is supplemented by heated air generated by an electric heating tube in a heating box connected to the inside of the machine, dry the workpiece.
    It is suitable for the drying, dehydration and degreasing processes of small hardware and mechanical parts such as electroplated parts, watch parts, tableware, springs, screws, plastics, electronic components, etc.

    ShineTec's centrifugal dryer
  • 2. Are centrifugal dryers the same as home dryers?
  • No, centrifugal dryers are completely different machines from household dryers. They belong to different application fields. Centrifugal dryers are industrial equipment used to heat and dry hardware parts, mechanical parts, and precision parts. The power requirements for commonly used machines are 380V/3-phase/50Hz, while household Dryers all use 220V/single phase/50Hz, so the working principles of centrifugal dryers are completely different and cannot be confused.
  • 3. What is the use of a centrifugal dryer?
  • At present, most of the deburring and polishing processes using vibrating, tumbling, and polishing processes use wet finishing process with water, chemical finishing compound, chemical polishing compound and other chemical liquid. After polishing, there will be residual moisture on the surface of the product or a small amount of polishing liquid that has not been cleaned. If not dried, the workpiece will be easily oxidized or corroded when exposed to the air. Only after centrifugal drying with with hot air blowing can the surface be kept dry to prevent corrosion and rust.
  • 4. How to use centrifugal dryer?
  • Using the centrifugal dryer is as follows:

    4.1 First, place the centrifugal dryer and dehydrator on a flat ground. A little trick for installation is to place the machine directly on a used car tire. This can prevent the machine from shaking and facilitate installation.

    4.2 Before starting the dryer, check whether the power switch is working properly and whether the fixed position of the stainless steel inner barrel in the machine is in place. The rotation direction of the barrel body should be in the same direction as the arrow. Turn on the electric heating switch and check whether hot air is discharged after a few minutes. If there is still no hot air after 5 minutes, stop the machine and check whether the air outlet is blocked.

    4.3 The lid must be closed during the dehydration and drying process, and the machine must be stopped when loading and unloading the inner barrel. Note that the materials in the barrel must be rotated evenly before starting, otherwise the centrifugal drying machine will shake violently due to unbalanced centrifugal force.

    4.4 Before stopping, it is best to disconnect the power supply and then apply the brakes. Do not brake without turning off the power supply. The dehydration dryer can only dehydrate without heating, but it cannot only heat without rotating the motor.
