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 ).

• Selective grinding – Grinding operation is carried out in various stages depending upon the differences in structural and mechanical properties of components of grain . Degree of grinding • Ratio of the overall surface area of the ground product to the overall surface area of the feed Dg = Sp/Sf . Dg – degree of grinding
