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.
In centerless grinding, the work is supported on a work rest work "blade" between the regulating or "feed" wheel and the grinding wheel, The feed wheel controls and drives the work; the grinding wheel, running at normal speed, does the grinding.
