Examples of CBN grinding wheels

CBN is the second hardest known material after diamond. It is synthesised from boron
and nitrogen in a high-pressure and high-temperature process similar to the production
of the synthetic diamond from which it differs by its higher thermal stability. Compared
to conventional abrasives, CBN offers advantages when grinding difficult-to-cut steels
(hardness >55 HRC). Due to the low wear of the grinding wheel, high geometrical and
dimensional accuracy can better be observed. Moreover, tools ground with CBN have
a longer tool life, because the cool grinding CBN hardly affects the structure of the
surface zone.
