Insert GradesCoate dCarbideCermetCarbideCBNPCDCeramic Grade CBN High hardness and thermal resistance for machining hardened steel and hard cast iron. High-speed finishing of gray cast iron with long tool life is also possible. In 1977, Sumitomo Electric Hardmetal successfully developed a revolutionary CBN sintered tool called SUMIBORON. The main component in SUMIBORON is cubic boron nitride with a special ceramic binder sintered under super high pressure and temperature. Compared to other conventional tool materials, CBN has higher hardness and excellent thermal resistance. With these distinct characteristics, SUMIBORON can perform machining of hardened steel, hard cast iron and exotic alloys which was previously only done by grinding. Excellent efficiency and longer tool life can also be achieved from high-speed A finishing of cast iron.
