Centerless Grinding 101
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.
