Selecting the right abrasives for your operation
Many abrasive manufacturers offer wheels for most types of cutting, slicing, and grinding operations. Common types include depressed-center wheels (type 27), flat wheels (type 1), cup wheels (type 11), semiflexible wheels (type 29), and an assortment of special-purpose wheels. The appropriate choice often depends on the geometry of the work.

A combination of the cutting pressure and capability of the grinding wheel and the gravity acting on the workpiece ensures that the work maintains contact with the control wheel and the rest blade. The control wheel (or regulating wheel) is normally made from a rubber bonded material that offers a frictional surface that is constantly advancing.
Difference Between Machining and Grinding
Grinding. Machining is one bulk material removal process (i.e. high MRR). Thus it is economical and suitable to give proper size and also for semi-finishing. Grinding has low material removal rate and is preferred only for finishing. Accuracy and tolerance achieved by conventional machining operations are not so good.

Grinding is the most common type of material cutting and surface generation process. Mostly grinding process is used to shape and to provide better finishing parts of metals. Grinding process uses one abrasive tool to make controlled contact with workpiece surface. Normally grinding wheel is used as abrasive tool in process of grinding.
Grinding and Polishing - ASM International
Some companies do not distinguish between grinding and polishing, as in the previous paragraph, but use the term lapping to mean grinding or coarse polishing with an abrasive slurry against a hard metal platen. Lapping is used in ceramography and ceramic manufacturing to produce extremely flat surfaces.
