Type 5. It is used for surface grinding, i.e. production of flat surfaces. Grinding takes place with the help of face of the wheel. Type 6. It is used for grinding flat surfaces with the help of face of grinding wheel.
Centerless Grinding. Centerless grinding is a high production process for continuously grinding surfaces in which the workpiece is supported not by centers or chucks, by a blade (figs. 16.1 a and b). Typical parts made by centerless grinding are roller bearings, piston pins, engine valves, camshafts, and similar components.
