Centerless grinding is the process of removing material from the outer diameter of a workpiece using a grinding wheel. The workpiece is located on its outer diameter and supported by a working blade located between the adjusting wheel and the grinding wheel. The adjustment wheel drives the machined parts, and the grinding wheel removes material.

In through-feed grinding, the part rotates between the grinding wheel and a regulating wheel. For through-feed grinding, one or both wheels of the centerless grinding machine are canted out of the horizontal plane. This imparts a horizontal velocity component to the work piece, so that outside feed mechanisms are not necessary.

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.
