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-content CBN, solid CBN insert with multiple cutting edges. Applied in roughing to finishing of fully pearlitic gray cast iron, chilled irons, high-chrome alloyed steels, sintered powdered metals, and heavy cuts in hardened steels (>45 HRC). Use for finishing chilled and fully pearlitic cast iron. Solid inserts offer better security and shock resistance than tipped inserts, while also enabling deeper depth-of-cut capability.
