Centerless grinding is used to produce small parts in high volumes where the ground surface has no relation to any other surface except as a whole. Ground surfaces of 200-500 min. rms are usually considered acceptable for many applications and are a starting point for further finishing operations which include lapping, honing, and superfinishing.

In centerless grinding, the workpiece is held between two grinding wheels, rotating in the same direction at different speeds.One grinding wheel is on a fixed axis and rotates so that the force applied to the workpiece is directed downward. This wheel usually performs the grinding action by having a higher linear speed than the workpiece at the point of contact.

Centreless grinders The external grinding principle is also applied to the internal grinding. In internal centreless grinding the work piece is supported by three rolls. One is the regulating roll, and the other is pressure roll to hold the work piece firmly against the support and the regulating rolls. This is illustrated in the diagram below.

Types of Cylindrical grinding machine with Diagram Explained. This machine is used to produce external cylindrical surface. The surfaces may be straight, tapered, steps or profiled. Broadly there are three different types of cylindrical grinding machine as follows: 1. Plain centre type cylindrical grinder. 2. Universal cylindrical surface grinder.

Surface finish refers to the process of altering a metal's surface that involves removing, adding, or reshaping. It is a measure of the complete texture of a product's surface that is defined by three characteristics of surface roughness, waviness, and lay. The surface roughness is the measure of the total spaced irregularities on the surface.
