信和精工 List of Products and Services

We provide machining technology for micro-diameter shafts. To overcome the challenge of "lightweight = instability" associated with machining small diameter shafts, we have made unique improvements to our centerless grinders. Please feel free to contact us if you have any requests. 【Machining Precision】 ■ Machining Diameter: φ0.4 ±0.001mm ■ Machining Length: L = 1.0mm or more ■ Roundness: 0.001mm or less ■ Surface Roughness: RY0.3μ or less *For more details, please feel free to contact us.

We provide surface treatment technologies to accommodate high density. By removing the large amounts of alumina and silica that adhere to the surface of shafts for fluid bearing motors, it is possible to ensure the product's lifespan. Please feel free to contact us if you have any requests. 【Processing Methods】 ■ Passivation treatment ■ Barrel treatment ■ Electroless nickel plating ■ Alumina and silica-free treatment ■ Specified surface roughness treatment *For more details, please feel free to contact us.
