Centerless grinding

From Wikipedia, the free encyclopedia

Centerless grinding is a method of material removal through grinding, similar to centered grinding except for the absence of the spindle. It has high through-put, i.e. large number of parts can be manufactured in a short time.

The work-piece is set-up between the regulating wheel and the grinding wheel, and is supported by the workblade.

Centerless grinding can be defined by two particular types; one is plunge grinding where a part is placed between the wheels on a workblade and a wheel is "plunged. The other is throughfeed where parts are fed into the machine, grind along the workblade and exit the rear of the grinding wheels.

Some of the benefits of centerless grinding include the ability to grind parts with geometries that do not allow them to be OD ground, the ability to remove three, five and other odd numbered lobing on the shaft of a part, and to maintain size beyond what is typically capable of an OD grinder due to the low overall pressures spaced out along the workpiece.
