Workholding for Cylindrical Grinding

 · The most widely used workholding method for cylindrical grinding is done between centers. Between-centers grinding does not require a centerless ground workpiece. In fact, many agree that the only way to create a perfectly round part from raw stock, in one setup, is to grind between centers. Many tool designers start with this methodology in mind.

Centerless Grinding

Among the many types of grinding, the most common are surface grinding, cylindrical grinding, internal grinding, and centerless grinding. Surface grinding is used to grind flat surfaces. The grinding wheel can be horizontal or parallel (vertical). Vertical wheel type uses a rotary table and can grind multiple workpieces at the same time.
