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.
A high CBN content, solid CBN with multiple cutting edges and a CVD — Al203-TiN-TiCN-Al203-TiN alumina coating. Applied in roughing to semi-finishing of fully pearlitic gray cast iron, chilled irons, high chrome alloy steels, sintered powdered metals, and heavy cuts in hardened steels (>45 HRC). Use for finished chilled and fully pearlitic cast iron. Do not apply on finishing hardened steels. The solid WBH40C also can be effectively applied when roughing hardened steels.
