Come Crank Film Polishing

Super finishing of various types of cams and crankshafts.

Our company has developed various film polishing machines with the concepts of "high precision" and "environment" and has provided them both domestically in Japan and globally. Based on our technology, experience, and long-standing achievements, we are a manufacturer that designs and manufactures according to customer requirements. Our outer diameter polishing machines are mainly introduced in the final finishing processes of various automotive parts such as crankshafts and camshafts, contributing to improved roughness and stable process capability values. 【Applications】 ◆ Cam and crankshafts for four-wheel vehicles ◆ Cam and crankshafts for two-wheel vehicles ◆ Cam and crankshafts for outboard motors, etc. The polishing capability of film polishing is said to be able to target a roughness that is about half of the previous roughness per process. For example, it is possible to reduce a shaft with a previous roughness of Rz=1.6μm to a roughness of Rz=0.8μm or less in 15 seconds. (Refer to the diagram) Additionally, since film polishing is a contour-following process, it is possible to improve roughness without altering the original shape.
