We would like to introduce the "grinding processing" that we conduct. In flat grinding, our goal is to bring flatness, parallelism, and perpendicularity closer to zero. In cylindrical and internal grinding, we aim to achieve roundness, cylindricity, coaxiality, perpendicularity, and angular intersection as close to zero as possible. The angles for internal grinding can be processed up to a maximum of 179°. Additionally, if a fine surface roughness is required, we perform lapping processing, and mirror finishing is also carried out simultaneously. 【Processing Details (Partial)】 ■ Flat grinding ■ Internal grinding ■ Lapping processing ■ Mirror finishing ■ Spherical processing *For more details, please refer to the PDF document or feel free to contact us.
