Grain size is determined by factors such as the purpose of grinding, the work condition and shape/dimension of the wheel. Generally, grain sizes within the range of F46-F180 are used.
3) Grade
Generally, harder grade (grade L-Q) wheels are used because of the grinding condition and other constraints (such as operating speed, wheel shape and tools used).
4) Structure
Wheels of comparatively dense, high in grain ratio (structure No.8 and lower numbers) are usually used.
5) Bond
Vitrified (V) bonded wheels are most commonly used. However, impact resistant wheels such as resinoid (B), rubber (R), and urethane (UP) bonded wheels are also used.
