Сверхтвердые режущие материалы компании Сумитомо (Япония) КНБ (кубический нитрид бора) CBN (Cubic Boron Nitride) SUMIBORON Обработка закаленных сталей _ и чугуна High hardness and heat resistance for cutting high hardness steel and hard cast iron. Long tool life with high-speed finishing of grey cast iron. In 1977, Sumitomo Electric Hardmetal successfully developed a revolutionary CBN sintered tool -SUMIBORON. The main component in SUMIBORON is Cubic Boron Nitride with a special ceramic binder sintered under super high pressure and temperature. As compared to other conventional tool materials, CBN has higher hardness and excellent heat resistance. With these distinct characteristics, SUMIBORON can perform machining of hardened steel, high hardness cast iron and exotic metals where previously only grinding was done. Furthermore, excellent efficiency and longer tool life can also be achieved from high speed machining of cast irons.

Strong CBN binding force gives superior wear resistance and toughness when cutting hardened steel and cast iron. BNC500 can also be used with cast iron, while BN350 can also be used with sintered ferrous alloys.
