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.
