A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the m aterial. It is a process of metal cutting by using a rotating abrasive whee l from the surface of the workpiece. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.
The heat carrying capacity of the wheel is required to be higher for the higher temperatures generated due to grinding carried out at high speeds. If the porosity is kept higher for this purpose, when the grinding wheel rotates at a high speed, there is a possibility that the strength of the grinding wheel may be less.

Principles of Grinding. In all forms of grinding, three different interactions occur between the abrasive and the machined material. Cutting occurs where the abrasive grain is sufficiently exposed to penetrate the workpiece material and curl a chip, and sufficient clearance exists between the grain, bond and workpiece to flush the chip with coolant or throw it away by …
