Grinding Concepts. Precision Grinding is an abrasive machining process that uses a grinding wheel as the cutting tool.. A grinding wheel is an expendable wheel used for various grinding and abrasive machining operations. Grinding wheels may also be made from a solid steel or aluminium disc with particles bonded to the surface.
