In centerless grinding, the workpiece is held between two grinding wheels, rotating in the same direction at different speeds.One grinding wheel is on a fixed axis and rotates so that the force applied to the workpiece is directed downward. This wheel usually performs the grinding action by having a higher linear speed than the workpiece at the point of contact.
Centerless grinding is a machining process that uses abrasive cutting to remove material from a workpiece. Centerless grinding differs from centered grinding operations in that no spindle or fixture is used to locate and secure the workpiece; the workpiece is secured between two rotary grinding wheels, and the speed of their rotation relative to each other determines the rate at …

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.
Centerless grinding is the process of removing material from the outer diameter of a workpiece using a grinding wheel. The workpiece is located on its outer diameter and supported by a working blade located between the adjusting wheel and the grinding wheel. The adjustment wheel drives the machined parts, and the grinding wheel removes material.

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 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.
