  • ELID Grinding and Polishing - ScienceDirect

    01/01/2015  ELID grinding was first proposed by the Japanese researcher Hitoshi Ohmori back in 1990. The most important feature is that no special machine is required. Power sources from conventional electrodischarge or electrochemical machines can be used for ELID, as well as ordinary grinding machines.
