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.

During mill operation, grinding balls wear and are reduced in size. In doing so, the grinding characteristics change. The extent of wear would depend on the characteristics of the rock present, such as surface hardness, density and composition. The abrasive action on the surface of the balls increases with time.

Advantages of Grinding operation: This can produce a high surface finish with accurate can obtain. This can machine hard materials. This operation can be done with less pressure applied on work. It can obtain highly accurate dimensions. It can work at high temperature also. Speed of cutting can be done by this process.

It is a means of altering material surfaces through processes involving adding, removing, or reshaping the metal surface. Three (3) major characteristics can define the surface finish. They are surface roughness, waviness, and lay. The measure of the total space irregularities on the surface metal is known as Surface Roughness.

If the goal is to improve the current surface finish from 20 microinch Ra to 17 microinch Ra, then simply increasing the wheel speed and/or reducing the feed rate slightly might be sufficient. However, if a finer surface finish is required, then these five factors should be addressed. 1. Grinding Operational Parameters.
