Centerless grinding is the process of removing material from the outside diameter of a work piece using an abrasive wheel. In its simplest form, a centerless grinder consists of the machine base, grinding wheel, regulating wheel and work blade. With centerless grinding, the work piece is not mechanically held to drive the part.

Basic Principles. In 1953 Schleicher developed the first centerless grinding machine for needle grinding. In 1915 Heim introduced workrest plate and control wheel, which improved the performance and enlarged the field of application (Rowe 1964).Since then, centerless grinding is highly applicable for large batch and mass production.

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.
