Nickel-based superalloys are to be processed with cubic boron nitride tools.

Cubic boron nitride (CBN) is one of the isomers of boron nitride BN. Similar to diamond, it is a superhard material synthesized by ultra-high temperature and ultra-high pressure technology. Its hardness is second only to diamond (microhardness of up to 8000 ~ 9000 hv), thermal stability and high (1250 ~ 1350 ℃), large chemical inertness of iron group elements, strong resistance to cohere can force, with diamond grinding wheel grinding edge, so it is suitable for processing more than 35 HRC hard material, such as a variety of hardened steel, carbon tool steel, alloy tool steel, high speed steel, bearing steel and die steel, etc.), chilled cast iron, cobalt and nickel based high temperature alloy, hard alloy, surface spraying (welding) materials such as hard and wear-resistant materials, It can also be used for processing titanium alloy, pure nickel, pure tungsten and other materials. It is one of the best tools for turning and milling instead of grinding.
