Process optimization is an essential exercise for today's evolving and adapting machine shop. Increasing international competition, short part runs and need-it-yesterday delivery requirements demand it. Unfortunately, optimizing a camshaft lobe grinding process has never been cut and dry.

Through the grinding process, you've got the material from the valve, you've got the breakdown material from the wheel and it circulates through and gets packed into the wheel during the grinding process. It's important to have a nice, sharp, pointy dressing diamond to remove that build up and give you a good, clean, cutting abrasive.

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.

To grind the valves and head we need some grinding paste. The paste is simple enough – powdered carborundum suspended in a grease base. Buy a small tub and it'll last you a lifetime. The carborundum is a powerful abrasive, that wears the metal away from the valve and seat, making them perfectly smooth in relation to each other.
