A study on the micro electric discharge grinding characteristics of WC-Co-relationship between surface integrity and dielectric conditions-

Abstract

In this paper, wire electric discharge grinding(WEDG) method for machining a micro shaft was introduced and the machining characteristics was investigated. From the experimental results, it was concluded that high surface integrity could be obtained by use of dielectric fluid spray method and small capacitive condenser.
