Description of PCBN material

Cubic boron nitride is the second hardest material in the world invented successfully in 1957; the hardness of CBN’s single crystal is HV8000-9000 while the hardness of PCBN is HV 2500—5000, so its considerably better abrasive resistance than tungsten carbide and ceramics. With a higher ability of oxidation resistance within 1000℃, CBN will do not have any chemical reaction together with ferrous material in 1200--1300℃. So it is unique for CBN material dry cutting ferrous materials. The principal application areas for CBN cutting tools are hardened steels, cast irons and sintered irons as well as powder metallurgy components.

Features and Benefits of PCBN:

1. Excellent surface finish

2. High speed turning, high performance

3. More flexibility in machining

4. Less investment in machines

5. Not required coolant

6. Easier in recycling and treatment of chips

7. Easier in removal of outlet of chips
