Conventional Abrasives Grinding Wheel Types


Some common types of grinding wheels made with conventional abrasives (aluminum oxide and silicon carbide).

Note that each wheel has a specific grinding face; grinding on other surfaces is improper and unsafe.

(a) Type 1—straight;  (b) Type 2—cylinder;  (c) Type 6—straight cup;

(d) Type 11—flaring cup;  (e) Type 27—depressed center;  (g) Mounted;



Grinding Wheels Marking System



Standard marking system for aluminum-oxide and silicon-carbide bonded abrasives.


2. Superhard Abrasive Grinding Wheels;



Examples of superabrasive wheel configurations. The rim consists of superabrasives and the wheel itself (core) is generally made of metal or composites.


Note that the bonding materials for the superabrasives are: (a), (d), and (e) resinoid, metal, or vitrified; (b) metal; (c) vitrified; and (f) resinoid.
