초연삭입자와 ELID를 이용한 고정밀 고능률 연삭가공

High Precision and Effective Grinding using Super Abrasives and ELID

In this study, the grinding characteristics of CBN wheels, such as grinding force and surface roughness, have been compared and analyzed from various working conditions of spindle speed and depth of cut. To actualize high efficient grinding at ceramic and silicon nitride material, electrolytic in-process dressing (ELID) method has been applied at metal bonded diamond and CBN wheels. Super precision grinding using ductile mode at difficult-ta-cut materials could be performed.
