GEAR GRINDING Grinding wheels are used to correct or modify the profile of gear teeth after heat treatment. The machine and gear type determine the shape of the grinding wheel. Continuous gear generation, profile grinding, bevel gear grinding, and power honing are the most common grinding processes in gear grinding.

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 ).
General procedures for preparing solid samples (such as drying, obtaining a constant weight, grinding, sieving, mixing, and subsampling) are discussed. Some sample preparation procedures then are presented for typical types of solid samples (e.g., soil and sediment, biota, food, etc.). This chapter concludes with specific guidance for preparing
