Jun 15, 2021What Is Centerless Grinding? Centerless grinding works best at machining the outside diameter of simple, cylindrical parts. It involves feeding a workpiece between a stationary grinding wheel rotating at high speeds and a slower regulating wheel which spins and drives the part, in the case of through-feeding.

Centerless Grinding consist of grinding cylindrical workpieces without centers. The workpiece revolves between two wheels. One wheel is called the regulating wheel the other is the grinding wheel. The grinding wheel generally travels at a fixed RPM and the regulating wheel travels at a selected slower speed to control the rate of spin of the of the part.
