Rolls grinded on a cylindrical grinding machine are suitable
for super finish polishing in order to obtain much lower surface roughness. The
surface roughness can be reduced to ra: 0.01 µm with this automatic feed system
in which the rolls are rotated.
Polishing Belts made of aluminium oxide or pure diamond are
used for super finish polishing of coatings such as hard chrome, tungsten
carbide, chrome carbide, ceramic, metal combination.
