material removal with centerless grinding. If you had 400 pcs of .442 diameter parts 6" long made from .5 diameter PHT 4140, would you turn most of the material first, then get it centerless ground, or leave it in 12' lengths and centerless grind all the material off? It needs to be ground for surface finish and size tolerance.

In thrufeed centerless OD grinding the workpiece passes between two wheels, a grinding wheel and a regulating wheel (as illustrated in the diagram, right). Both wheels rotate in the same direction, but at much different speeds. The purpose of the grinding wheel is to remove material from the workpiece and improve part OD quality.

Centerless grinding is an OD grinding process. It differs from other cylindrical processes in that the workpiece is not mechanically constrained. On traditional OD machines, the work is held between centers or chucked and rotated against the faster spinning grinding wheel by an external motor usually located in a workhead.
