What Is End Feed Grinding?

End-feed grinding is a technique used in machining when working with a centerless grinder. A centerless grinder is a machine that has two wheels through which a material is placed in order to shaped and ground. The reason the centerless grinder goes by the name that it does is because it has no spindle like a centered grinder.

Through-feed Centerless Grinding Advance Grinding

Through-feed grinding Techniques. Through-feed grinding is performed by tilting the horizontal axis of the regulating wheel. Thus, centerless grinding can efficiently regulate the feed rate of the workpiece during this operation. The workpiece, or bar, is fed into the grinding wheel and the regulating wheel.
