1011 Magnetic Polishing of Micro Channel using a Ball-Nose End-Mill Type Tool with a Compact Machine Tool

Abstract

In order to inspect the effect of a magnetic polishing method for an even surface (plane surface) and an uneven surface (concave and convex shape), we polish and compare with a plane surface, a concave shape and a convex shape. Results showed that a high rotation speed is good for plane polishing as well as whetstone grind, while for polishing the concave and convex shapes, a low rotation speed is more effective. We also found that, with the concave and convex shapes, the polishing effect worsened due to excess paste that inhibited rotation movement of the paste to the pile on the wall surface.
