BNC2010/BNC2020Coated SUMIBORON for Hardened Steel Machining

First choice for Longer Tool Life and Cost Reduction

• General Features Provides improved machining accuracy and longer tool life as compared to conventional Coated SUMIBORON by combining newly developed CBN substrate and ceramic coating. Exhibits excellent performance in high-precision and general cutting of hardened steel and enables reductions in machining costs.

BNC2020

• Characteristics
• BNC2010 ・For high-precision finishing requiring good surface roughness and dimensional accuracy.

Ideal for high-precision machining thanks to excellent wear resistance. ・Further maintains excellent surface roughness. Consistently excellent surface roughness thanks to coating with high notch wear resistance and CBN substrate.

• BNC2020 ・General-purpose grade suitable for typical hardened steel machining applications.

Achieves further stability in machining of a wide range of hardened steel components. ・Achieves long tool life thanks to highly wear-resistant, highly adhesive coating and tough CBN substrate. Achieves stable and long tool life even in high-efficiency and interrupted machining.
