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

Centerless Grinding Design Rules - eFunda

Centerless Grinding Guidelines: The largest diameter of the workpiece should have the ground surface, if possible. This allows through-feed grinding. The axial length of a centerless-ground workpiece should be at least equal to the diameter. Short workpieces are more susceptible to surfaces that deviate from right circular cylindricity.
