[1] In centerless grinding, the workpiece is held between two wheels, rotating in the same direction at different speeds, and a work-holding platform.
[1] The speed of the two wheels relative to each other provides the grinding action and determines the rate at which material is removed from the workpiece.
The grinding wheel turns faster, slipping past the surface of the workpiece at the point of contact and removing chips of material as it passes.
Through-feed grinding can be very efficient because it does not require a separate feed mechanism; however, it can only be used for parts with a simple cylindrical shape.
Before the process begins, the workpiece is loaded manually into the grinding machine and the regulating wheel is moved into place.
