BNC500Coated SUMIBORON for Ductile Cast Iron Machining

Coated CBN Grades for Ductile Cast Iron Machining

• General Features Broad improvements in the toughness of the CBN sintered body 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. Highspeed 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 cast iron.
• Characteristics Achieves a Long, Stable Tool Life in High Speed Machining of Ductile Cast Iron

BNX10 Superior wear resistance, makes stable machining possible under high-speed conditions.

BNC500

• Supports High-precision Machining Can maintain excellent dimensional tolerance and surface roughness over many hours.
