Centerless grinding Wikipedia

In centerless grinding, the workpiece is held between two wheels, rotating in the same direction at different speeds, and a workholding platform. One wheel, known as the grinding wheel (stationary wheel in the diagram), is on a fixed axis and rotates such that the force applied to the workpiece is directed downward, against the workholding platform. This wheel usually performs the grinding action by having a higher tangential speedthan the workpiece at the point of contact. The other wheel, known as the regula
