SUMIBORON Coated SUMIBORON BNC500 Ductile Cast Iron Coated CBN grade for ductile cast iron machining I General Features Further improvements in the toughness of the sintered CBN and wear resistance from the application of a newly developed high-purity TiC binder. In addition, it demonstrates exceptional wear resistance by combining a ceramic coating with excellent heat resistance. High-speed and high-precision machining is achieved when finishing ductile cast iron. It also provides a long, stable tool life in machining high-strength ductile cast iron, special cast irons such as vermicular cast iron, and centrifugally cast iron. I Characteristics Achieves a Long, Stable Tool Life at vc=400 m/min Superior wear resistance, makes stable machining possible under high-speed conditions. Supports High-precision Machining Can maintain excellent dimensional tolerance and surface roughness.
