Patents for various magnetically driven, shoe centerless fixtures for OD grinding began to appear in the mid-1940s. The regulating wheel is replaced by a "shoe" that contacts the part and opposes the force from the grinding wheel. A second shoe located near the grinding wheel itself replaces the work rest and provides additional radial support.
The recommendation to the companies was the introduction of a positioning system for the adjustment of the coolant supply nozzles and verification of the applicability of shoe nozzles for the grinding process. 5.2. New processes for special requirements. Some classical grinding problems require dedicated or specially designed processes.
Basics of the Centerless Grinder provides a comprehensive introduction to centerless grinding. Centerless grinding includes both internal and external grinding operations.

Grinding. For the grinding of the outer ring, the side surface of the ring is first ground. Then the outer surface is ground so that it is precisely perpendicular to the side surface. Then using the outer surface as a reference, the raceway groove is honed. The same process applies to the inner ring. Making of Steel Balls
