he wheels are generally made from a matrix of coarse particles
pressed and bonded together to form a solid, circular shape, various
profiles and cross sections are available depending on the intended
usage for the wheel. They may also be made from a solid steel or
aluminium disc with particles bonded to the surface.
The manufacture of these wheels is a precise and tightly controlled
process, due not only to the inherent safety risks of a spinning disc,
but also the composition and uniformity required to prevent that disc
from exploding due to the high stresses produced on rotation
Grain size, from 8 (coarsest) 1200 (finest), determines...
