PCBN T-CBN C463 Polycrystalline Cubic Boron Nitride Compacts (PCBN) T-CBN Application Grade Hardness Microstructure (Hv) Transverse rupture strength (GPa) Coating layer Features Main composition Thickness S Difficult-to-cut materials BX950 ip 3900-4100 1.80-1.90 Used for high-speed turning of heat resisting alloys ferrous metals and cast irons and highspeed milling of cast irons. Hardest T-CBN grade featuring high content of CBN sintered with cobalt based binder. Provided with high transverse rupture strength comparable with cemented carbides. BX450 pip 3100-3300 0.95-1.05 Applicable for machining ferrous sintered metal (especially for valve seats). Features fine grained CBN sintered with a special ceramic binder. Excels in chipping resistance and finished surface roughness. BX470 4100-4300 1.90-2.10 For ferrous sintered material. Extremely sharp cutting edge for excellent surface finish at minimum burr occurence. H Hard materials BX480 ii4100-4300 1.90-2.10 For ferrous sintered material and hardened roll steels. It is highest of CBN contents and hardness in T-CBN grades. BX310 0.80-0.90 Suitable for high-speed continuous turning of hardened steels and other hard materials with hardness of 54 to 65 HRC. Features fine grained CBN sintered with a special ceramic binder and especially excels in wear resistance. BXC30 1 2800-3300 0.85-0.95 (PVD) 2 Suitable for continuous to light interrupted turning of hardened steels and other materials with hardness of 54 to 65 HRC. Features fine CBN grain sintered with special ceramic binder and smooth surface of newly developed PVD coated layer. Excels wear resistance and good surface roughness BX330 mmmmM 0.85-0.95 Suitable for continuous to light interrupted turning of hardened steels and other hard materials with hardness of 54 to 65 HRC. Features fine grained CBN sintered with a special ceramic binder and excels in wear resistance and surface roughness. BX360 hmfmBl 1.00-1.10 (PVD) - Used for light to heavy interrupted turning of hardened steels and other hard materials with hardness of 54 to 65 HRC. Features fine to medium sized grain CBN sintered with a special ceramic binder and excels in impact resistance.
