Centreless grinding of crankshaft bearing journals is in many respects similar to camshaft grinding. The main differences are: Camshafts are rough ground directly from the cast condition, while crankshafts may have to be pre-turned. The diameter tolerances for crankshafts are often even tighter than those for camshafts.

cylindrical grinding (also called center -type grinding) is used to grind the cylindrical surface and shoulders of the workpiece. There are five different types of cylindrical grinding: outside diameter (OD) grinding, inside diameter (ID) grinding, plunge grinding, creep feed grinding, and centerless grinding.
Cylindrical grinding is usually done between centers by means of one grinding wheel. A centerless incorporates the use of two wheels, the regulating wheel, and the grinding wheel.
Centerless grinding machine is one of the grinding machine types. Grinding machine is a powerful machining tool that grinds a workpiece using an abrasive/grinding wheel. Abrasive wheel surface has small rough grains, which in contact with the workpiece apply shear force that cause shear deformation.
