Centerless Grinding - an overview | ScienceDirect Topics

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.
