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.

Starting with a rod of material, the PG-9BHD can produce intricate cylindrical shapes, or even grind the rod directly into balls. The unique oscillating regulating wheel assembly, used in ball form applications, forces parts to rotate randomly while grinding. This ensures sphericity -- the 3-dimensional roundness of the ball.
