The hardness of SiC single crystal is very closer to that of diamond, which makes it greatly difficult to process SiC single crystal. It is usually machined by lapping, but this technique requires a long machining time, resulting in low productivity, So we examine the possibility of ELID grinding in SiC single crystal. Results show that with the use of ELID, mirror surfaces can be achieved ...
