Centreless grinding. As Dhavlikar et al. [] describe centreless grinding is a common manufacturing grinding process for round workpieces, thanks to its unique workpiece (WP) holding system.The WP is sustained along three contact lines, with the grinding wheel, the regulating wheel and the supporting blade (Fig. 1).This method removes the need to clamp the …

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.
