ELID Grinding and Polishing - ScienceDirect

ELID-lap grinding of silicon with JIS #4000 wheel was found to yield a mirror finish with a roughness of 3.8 nm, as compared to the 7.4 nm roughness obtained after conventional lap grinding. ELID-lap grinding of tungsten with JIS #4000 wheel allowed a more stable removal rate than conventional lap grinding over an 80-min period.

ELID grinding of SiC ultra lightweight mirror

21-11-2017 · ELID grinding method is the new grinding technology which one of authors invented, produces the quality of the high surface efficiently, and is effective in processing of a very hard material, such as crystalline silicon and sapphire, ceramics, glasses, hard metals and so on.

ELID grinding of silicon wafers: A literature review

in ELID grinding [1,11,13–17]. And it has been reported that mirror surfaces on silicon wafers could be achieved with ELID grinding [10,13,14,16,17]. However, ELID grinding has not been accepted by the silicon wafer industry as a manufacturing process. This review stone aims to …
