Benefits of centerless grinding include abilities to remove material to accurate specifications. The ability to grind parts with complicated geometries, the ability to grind a large number of parts and the ability to maintain tolerance.

Centerless grinding is a method of material removal through grinding. It is similar to centered grinding. In centerless grinding, however, there is no spindle. This is a high capacity method of material removal. Many parts can be ground quickly.

There are two wheels on a centerless grinder. The wheels are rotated in the same direction. The workpiece is set up inside the regulating wheel and the grinding wheel. The workpiece is supported by a work rest. The work rest is located between the wheels. The work is placed upon the work rest. The regulating wheel spins and forces the work against the grinding wheel.

Centerless grinding is classified into two types : throughfeed grinding, for which the workpiece is fed into the machine along the work rest and plunge grinding for which the workpiece is placed between the wheels on a work rest with the grinding wheel plunging into the workpiece.
