1. CBN is the only materials human knows now that its hardness is second only to diamond,its htermal stability & chemical interness is much better than diamond, can withstand 1300-1500°C ,even at °C,it does not happen phase change

2. CBN has low affinity with iron-based metal,so it can be used for the high speed cutting of iron-based metal,high precision & surface finished,cutting speed is 10 times than carbide,hardness& wear resistance is 50 times than carbide cutting tool ,25 times than ceramic tool.

1.hardness steel,ceramic,carbon tool steel ,alloy steel,bearing steel,high speed steel&HRC30~70 workpiece2.Ni & Fe base other         wear-resistant,corrosion,heat-resistant spray materials 
3.V-Ti cast iron,high phosphorus cast iron and chilled cast iron and other wear-resistant cast iron
4.TC4 and other titanium alloy
5.Some types of heat resistant alloys6.YG-type carbide workpieces,inseated of the diamond tool in some cases.

CBN tool is good at finishing ,semi-finishing & all kinds of hardend cast iron,high tempertaturer alloy & other difficut machining materials

Thin-wall machining/HSS slice cutting/HSS Groove cutting Tungsten carbide cutting /Mirror finishing cutting Ceramics machining.
