Centerless grinding is the process of removing material from the outside diameter of a work piece using an abrasive wheel. In its simplest form, a centerless grinder consists of the machine base, grinding wheel, regulating wheel and work blade. With centerless grinding, the work piece is not mechanically held to drive the part.

The cylindrical grinder is a type of grinding machine used to shape the outside of an object. The cylindrical grinder can work on a variety of shapes, however the object must have a central axis of rotation. This includes but is not limited to such shapes as a cylinder, an ellipse, a cam, or a crankshaft.

Centreless grinding is an OD grinding operation where the work piece seeks its own axis of rotation between the grinding wheel and a regulating wheel. The key components in the process are the grinding wheel, the work rest blade (used to support the work) and the regulating or "feed" wheel (the drive mechanism for the work piece).
Forms of Centerless Grinding The three forms of centerless grinding are through-feed, end-feed, and in-feed. Here is an explanation of the differences: Through-Feed Centerless Grinding – In this process, the workpiece is fed through the center of the two grinding wheels. This technique is best used for parts that are cylindrical in shape.
