Centerless grinding workblade angles range from 0 to 45 degrees. For most centerless grinding applications, a top blade angle of 30 degrees seems to provide the best results. "The basic rule is the steeper the angle of the blade the faster the rounding action," says Mr. Payne. "There are limits, however.

Centerless grinding is a machining process that uses abrasive cutting as a means for stock removal. What distinguishes centerless grinders from centered grinders is the absence of a spindle or fixture to secure the workpiece in place. The workpiece is secured between two wheels - a grinding wheel and a regulating wheel.
