Paper Abstract

ELID (Electrolytic In-process Dressing) grinding is a new ultra-precision machining technique which employs in-process electrolysis to dress the metal bond diamond wheel in grinding process. In this paper, the principle of ELID grinding is introduced. An optical glass sample is ground by using cast iron bond diamond wheel and ELID technique. Tested by WYKO RST Plus, the grinding surface roughness Ra is 2.48 nm. A conclusion can be drawn that using ELID technique can realize the ultra-precision grinding of optical glass.
