Precision grinding and polishing processing of metal parts - Hirai Seiko's processing technology
Introduction to the processing technologies we offer, such as "spherical grinding and polishing" and "R surface (curved surface) grinding and polishing"!
Our company specializes in "spherical grinding and polishing processing." Spherical grinding and polishing is most commonly used in the processing of hydraulic pump pistons, which are our main precision metal component products, and we can accommodate precision metal parts with diameters ranging from 4mm to 100mm. The processing accuracy allows for high-precision metal grinding and polishing with a diameter tolerance of 5μm, sphericity of 2μm, and surface roughness of Ra0.1μm in mass production. Additionally, we also offer "R surface (curved surface) grinding and polishing processing" and "shaft cutting grinding and precision processing." Please feel free to consult us when you need our services. 【Processing Overview】 ■ Spherical grinding and polishing processing ■ R surface (curved surface) grinding and polishing processing ■ Shaft cutting grinding and precision processing *For more details, please refer to the PDF document or feel free to contact us.
