"Sandblasting" is a polishing method that sprays silica sand onto products along with compressed air from a nozzle, performing deburring and scale removal. It is possible to carry out pre-treatment for painting, scale removal, and deburring. By combining it with barrel polishing, complex processing is also possible. We offer a variety of silica sands. [Workpieces and Features] ■ Capable of pre-treatment for painting, scale removal, and deburring ■ Can accommodate various quantities from small amounts to mass production ■ Complex processing is possible by combining with barrel polishing ■ We provide a wide range of silica sands (sand) *For more details, please refer to the related links or feel free to contact us.

• Wafer processing/polishing equipment

"GUM polishing" is a grinding process that uses a viscoelastic abrasive material (GUM) mixed with abrasive grains, which is flowed at low speed under high pressure to smooth products and remove cross burrs. It is possible to improve the surface roughness of inner surfaces, remove burrs, and create radii. By combining this process with barrel polishing, complex treatments can also be achieved. Please feel free to contact us when you need our services. 【Workpieces and Features】 ■ Suitable for processing in areas that tools cannot reach ■ Capable of improving the surface roughness of inner surfaces, removing burrs, and creating radii ■ Complex treatments are possible by combining with barrel polishing processes *For more details, please refer to the related links or feel free to contact us.

• Wafer processing/polishing equipment

"Vibratory barrel polishing" is a method where products and polishing materials inside the barrel chamber create alternating friction movements due to vibrations, resulting in polishing. Although the flow rate is slow, it is possible to provide a momentarily large frictional force due to the acceleration of the vibrations. Our company owns both circular and box types. [Workpieces and Features] ■ Although the flow rate is slow, it is possible to provide a momentarily large frictional force due to the acceleration of the vibrations. ■ High volume efficiency, making it excellent for mass production. ■ The basic method differs from rotating barrels and centrifugal barrels, resulting in significantly different finishes for the products. ■ Our company owns both circular and box types. *For more details, please refer to the related links or feel free to contact us.

• Wafer processing/polishing equipment

"Centrifugal barrel polishing" is a polishing method where multiple (four) barrel tanks rotate and revolve at high speeds, applying centrifugal force to the contents. The number of items processed at one time is smaller compared to rotating barrels. There may be significant damage to the products, necessitating countermeasures. Our company owns several machines, including custom-made models. 【Workpieces and Features】 ■ Processing can be done in a short time ■ Generally has 10 to 15 times the polishing power of rotating barrels ■ Compared to rotating barrels, there may be significant damage to the products, requiring countermeasures ■ The number of items processed at one time is smaller compared to rotating barrels ■ Our company owns several machines, including custom-made models *For more details, please refer to the related links or feel free to contact us.

• Wafer processing/polishing equipment

"Rotary barrel polishing" is a common barrel polishing method that involves the mutual movement of products, polishing materials, compounds, and water for polishing. Depending on the size of the barrel tank, it can handle processing from small to large quantities. Our company owns multiple machines ranging from 100L to 500L. Please feel free to contact us when you need assistance. 【Workpieces and Features】 ■ It is a very basic processing method among barrel polishing, capable of handling various products and performing versatile processing. ■ Although the processing time is longer, it results in minimal polishing unevenness and minimizes damage to the products, allowing for stable precision barrels. ■ Depending on the size of the barrel tank, it can handle processing from small to large quantities. ■ Our company owns multiple machines ranging from 100L to 500L. *For more details, please refer to the related links or feel free to contact us.
