In thrufeed centerless OD grinding the workpiece passes between two wheels, a grinding wheel and a regulating wheel (as illustrated in the diagram, right). Both wheels rotate in the same direction, but at much different speeds. The purpose of the grinding wheel is to remove material from the workpiece and improve part OD quality.

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.
