The centerless grinding process is characterized by a particular workpiece (WP) holding system. The WP is supported on three points by the grinding wheel, the control wheel and the workrest, also called supporting blade (see Fig.1).This configuration makes the process prone to roundness errors, depending on the initial setup of the machine []: WP center can oscillate and create a polyhedral ...

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.

This method would employ a centerless grind operation of the OD only; thru-feed (same diameter all the way across the tube) or . in-feed (stepped diameters on the OD of the tube). Since a very time-consuming operation - the ID grind - would be eliminated this process is favored for cost effectiveness.
