CBN Features

Cubic boron nitride (CBN) in hardness only to diamond. And the diamond is different, it is in the processing of ferrous metals chemical reaction hardly occurs. Through a  cubic boron nitride  high-pressure technology, people can carbide layer is bonded tightly  Abrasive grinding wheel  poly crystal cubic boron nitride coating. This poly-crystalline cubic boron nitride referred PKB. BZN * - blades can replace conventional  polycrystalline diamond  for hardening steel material treated (HRC 45-68) also enables high-speed finishing, cutting speed can reach 80-200 m / min. BZN * - pearlitic cast iron blade is also used for cutting and hard cast iron and alloy cast iron.
