Coarse grinding is done on a wet-belt grinder with 120 and 240 grit belts. The purpose of coarse grinding is to obtain a flat surface free from previous cutting tool marks. Medium grinding is accomplished using successively finer grits of metallographic grinding paper. The paper is supported on a hard, flat surface such as glass or steel.
THREAD GRINDING-Produce very accurate threads on hardened materials-Three basic methods are used. 1. Center type grinding with axis feed: (Work spins slower) similar to cutting thread in the lathe. difference a shaped grinding wheel is used instead of the point cutting tool. (even multiple shaped grinding wheel can be used ).
