PCBNfor cast ironfor ferrous materials

Cubic boron nitride is the second hardest material in the world invented successfully in 1957. The hardness of CBN’s single crystal is HV8000-9000 while the hardness of PCBN is HV2500-5000, so its abrasive resistance is considerably better than tungsten carbide and ceramics. With high temperature oxidation resistance at 1000℃, CBN will do not have any chemical reaction together with ferrous material at 1200-1300℃. So CBN material is ideal for cutting ferrous materials, the CBN cutting tools are used for cutting hardened steel, cast iron, sintered iron as well as powder metallurgy components. Features of Mini PCBN Tipped Insert 1. The mini PCBN tipped insert is the most economic inserts with competitive price. 2. Advanced welding technology is adopted, this PCBN insert has two or four cutting edges, with the thickness of 2.2mm. 3. The best choice of OD and boring cutting 4. Higher processing efficiency
