flow, either by manual grinding using shaped grinding tools, or by electro-grinding. (b) The internal surface of the cylinders of a car engine are turned on a lathe. The surface is then made smooth by grinding, followed by honing and lapping to get an extremely good, mirror-like finish. (c) Sand-paper is used to smooth a rough cut piece of wood. 2.

Types of Abrasive. There are two types of abrasive. Natural. Artificial or Synthetic. The Natural abrasives occur as minerals or rocks in the crust of the earth. Diamond, Garnet, Corundum, and Quartz are some examples of natural abrasives. The Artificial or Synthetic abrasive group includes a number of materials possessing very high hardness.

The type of bond selected depends on such factors as the wheel operating speed, the type of grinding operation, the precision required and the material to be ground. Most grinding wheels are made with vitrified bonds, which consist of a mixture of carefully selected clays. At the high temperatures produced in the kilns where grinding wheels are ...

The two major types of grinding are off-hand grinding and precision grinding. Off–hand grinding or non-precision grinding is where the grinding wheel is applied manually to the work or where the work is applied off-hand to the grinding wheel. Off-hand grinding includes snagging of castings/forging, tool sharpening, weld grinding, cutting off,
