Grinding and Polishing. Adapted from the 3rd edition, Encyclopaedia of Occupational Health and Safety. Grinding generally involves the use of a bonded abrasive to wear away parts of a workpiece. The aim is to give the work a certain shape, correct its dimensions, increase the smoothness of a surface or improve the sharpness of cutting edges.

The abrasive grains are held together by a bond and while cutting, the grains get free from the bond. As each grain starts taking a cut in the job, a chip starts forming out of it. It bends and ultimately breaks away from the job. As compared to other machining processes, the chip formed during grinding is quite smaller in size.

Abrasive Grain Processing - Abrasive grains for both bonded and coated abrasive products are made by graded crushing and close sizing of either natural or synthetic abrasives. Raw abrasive materials first are crushed by primary crushers and are then reduced by jaw crushers to manageable size, approximately 19 millimeters (mm) (0.75 inches [in]).
