Abstract
In this study, The ultra-precision finishing system is applicable to all kind of the cylnderical workpiece products fast and easy. This system was applied to chrome coated steel to investigate the characteristic of grinding; (1) 3$mu extrm{m}$ of abrasive film is not use for grinding performance. (2) Grinding condition of coated chrome steel would set up differently, in 30~12${\mu}{\textrm}{m}$, in 9~5${\mu}{\textrm}{m}$. (3) The surface roughness of chrome coated steel was about Ra 0.0009${\mu}{\textrm}{m}$ in abrasive grain size 5${\mu}{\textrm}{m}$.
