CBN is considered as
one of the greatest technological
improvements for grinding hardened
ferrous and superalloys materials.
It is a man-made crystalline material,
second in hardness only to diamond
with twice the hardness and four
times the abrasion resistance of
conventional abrasives and represents
the most thermally conductive material
known. Being a non carbon based material,
it does not chemically interact with
ferrous materials like diamond does
at high temperatures. This specific
characteristic makes CBN ideally
suited for machining ferrous materials
and superalloys.
This monocrystalline
product shows either a blocky or
an irregular (sharp, angular) crystal
shape. It exists in different colors
varying from black to brown-orange,
can be obtained in nickel-coated
version, and is available in a wide
range of mesh sizes or even in micron
sizes. Used in grinding wheels, CBN
provides increased productivity and
greater efficiency thanks to longer
tool life and reduced wheel wear.
Optimal performance is achieved when
combined with specific bond systems,
i.e. metal, resin but also vitreous
or electroplated.
