Ion shot dressing grinding for desk-top machine tools with V-Cam system

Abstract

Demand for micro-lens molds is on the increase. A desk-top machine tool as a system for the machining of micro-lens molds is expected. However, when a grinding wheel with a small diameter is used, the ELID grinding method experiences a problem related to the installation of the negative electrode.

In this research, for the purpose of machining of a micro-lens mold, we developed a system to realize electrolysis using the small type ELID grinding wheel that did not require the use of the negative electrode. The results indicate the successful development of an ion shot dressing grinding system that uses a nozzle type electrode. As a result, the use of a #4,000 wheel produces a finished roughness of RMS 2.0nm, with good form accuracy was good of P-V 0.8μm.
