Peripheral speed is determined by wheel diameter and rotational speed. The correlation between wheel diameter and rotational speed is: All grinding wheels have a resistance threshold. If a grinding wheel shatters when rotating, the pieces that fly off can cause serious damage. Abrasives manufacturers therefore indicate

Surface grinding machines usually have fixed work speeds of approximately 50 sfpm or have variable work speed ranges between 0 and 80 sfpm. As with cylindrical grinding, the higher work speeds mean that more material is being cut per surface foot of wheel rotation and therefore more wear is liable to occur on the wheel.

The cylindrical grinder is a type of grinding machine used to shape the outside of an object. The cylindrical grinder can work on a variety of shapes. However, the object must have a central axis of rotation. This includes but is not limited to such shapes as a cylinder, an ellipse, a cam, or a crankshaft. (De Souza and Catai, 2004)
