Grinding wheels are self sharpening to a small degree, for optimal use they may be dressed and trued by the use of grinding dressers. Dressing the wheel refers to removing the current layer of abrasive, so that a fresh and sharp surface is exposed to the work surface. Truing the wheel makes the grinding surface parallel to the

Some speculations on the mechanisms of abrasive grinding ...

The mechanisms of grinding, a predominantly fracture mechanism in brittle material, and polishing, a predominantly plastic shearing mechanism, appear quite different. However, in a number of cases it can be shown that the difference between the two mechanisms can be triggered by differences in depth of cut and abrasive size.
