抄録

A demand for the mold of micro-lens is on the increase. As a system for the machining of micro-lens mold, a desk-top machine tool is being expected. But, when the grinding wheel with the small diameter is used, the ELID grinding method has a problem about the installation setting place of the minus side electrode. In this research, we developed a system to electrolyze the small type ELID grinding wheel, This system was realized ELID grinding processing without using the minus side electrode, for the purpose of machining of micro lens mold. That result succeeded in the development of the ion shot dressing grinding system which uses a nozzle type electrode. As a result, when a #4,000 wheel was used, finished roughness was RMS 2.0nm, and form accuracy was good with P-V 0.8μm in the range of the effective diameter.
