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.
