By changing the film width and film application method, it is possible to polish the outer diameter part of all kinds and shapes. Although primarily used in the final finishing process for various automobile parts, it is suitable for improving the roughness of sliding parts and sealing parts. In addition, the outer diameter polishing unit can be applied to the polishing of the edge surface and slope surfaces. We also have a lineup of tabletop polishing machines with work piece turning mechanisms and a polishing unit that can be mounted on customer’s lathes.
