In Advances in CMP Polishing Technologies, 2012 (2) Cubic Boron Nitride (CBN) Cubic boron nitride is commonly known as Borazon TM CBN, and is a man-made synthetic abrasive. CBN is made from cubic boron nitride grains bonded by ceramic material. It is as hard as diamond on the Mohs scale, making it well suited for ferrous materials in lapping operations, as it will not carbonize when ...

The main advantage that mixed ceramic has over Cubic Boron Nitride (CBN) in hard part machining applications is the effect on part production costs. Whilst CBN has a better tool life, the cost per edge of a ceramic insert is a fraction of that of CBN (approx one twentieth) whilst feed rates (chip thickness around 0.1mm) and cutting speeds ...
