Polycrystalline cbn is a highly durable material, similar to diamond in its composition and properties. It can process a wide variety of materials, from steel and cast iron to alloys of high strength and hardness. In addition, PCBN can resist oxidation at high temperatures. These properties make it ideal for cutting tools.
Medium CBN grade good for continuous to light interrupted machining of hardened steels with high wear resistance and moderate fracture toughness
