Grey cast iron is one type mateials that is widely used in most fields. Even though it is not difficult to machine, but the castings surface usually has hard pot, stomach,sand and other defects, which will accelerate the tool wear or make the tool damage. When producing the castings with bulk qty, the damage of the insert or wear rapidly will reduce the efficiency, when finish turning the casting surface, changing the insert frequently will affect the process quality. Because of the large qty usage,both improve the efficiency and reduce the costs will bring large benefit. So manufacturers would like excllent cutting tools machining cast iron to reduce the costs or improve the efficiency.
CBN(Cubic Boron Nitride), which hardness is only second to diamond, is suitable for high hardness materials, such as hardened steel ,high hardness cast iron. In the past, most people thought that it can’t be used for machining grey cast iron. However with the development of the technology and long-term researchment, Halnn research cbn grade BN-300,BN-K20 and new cbn grade BNK30 , which is specific for high speed cutting grey cast ion.
