CBN（Cubic Boron Nitride）is known as the second hardest material after synthetic
diamond, with desirable characteristics include high hardness, strength, abrasion
resistance, thermal ability,chemical resistance, and an ability to maintain sharp cutting
edges during use, which exceed the values of conventional abrasives. In particular,
the properties of high thermal stability and chemical resistance make it suitable for
processing ferrous materials, an area where synthetic diamond is not normally employed.
By adjusting the TI (Tough Index) or TTI (Thermal Toughness Index),the friability and
strength of the CBN can be controlled to match different working requirement.
In addition to being harder at ambient temperature, it maintains this hardness over a
wide temperature range.
The thermal stability of CBN can reach 1400-1500℃, which is nearly twice as high
as the diamond's.
It makes CBN suitable for processing ferrous materials, an area where synthetic
diamond are not normally employed.
All products produced by Zhonnan Diamond Co,.Ltd are with improved surface
finish and have the ability to maintain sharp cutting edges during using.
CBN can be made into camshaft, crankshaft, fuel injector, transmission part, gear, CV joint,
power steering pump part,compressor part and so on,the properties of high thermal stability
and chemical resistance make it suitable for processing ferrous materials. It is widly used in
aerospace, automotive,machinery industries and general engineerings.
