Development of Plane Magnetic Abrasive Finishing Apparatus and its Finishing Performance (2nd Report)

Finishing Apparatus using a Stationary Type Electromagnet

Abstract

This paper describes a new plane magnetic abrasive finishing apparatus using a stationary type electromagnet and its finishing performance, in which a plane workpiece fixed on the repose table is machined by a high speed rotating magnetic pole moving in two dimensional directions. From the experimental results, it is found that 14 μm in machined depth of SK 4 hardened steel (HRC 63) is obtained and 10 μmR_max in surface roughness is improved to 0.3 μmR_max.
