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 …
A grinding machine is a tool or piece of equipment used for removing material from a workpiece via abrasion. They typically employ rotating abrasive wheels to shape, smooth, or finish workpieces through grinding. The machining process uses abrasive particles to remove material from a workpiece's surface.
Figure 2. 1 Power (P) is equal to the product of torque (T) and rotational speed (n): P = T x n. Torque is oficially expressed in Newton x meters (Nm). The oficial SI-unit for rotational speed is radians per second (rad/s). In grinding the accepted term is, however, revolutions per minute (rpm).

Basic Grinding Theory provides an overview of the general process of grinding . Grinding occurs at the point of contact between an abrasive wheel and a workpiece. Like any other cutting process, grinding removes material in the form of chips. In order for a wheel to grind properly, its abrasive grains must wear and self-sharpen at a consistent rate. Otherwise, …
