PCBN Inserts
Feature:
Long cutting lifetime, high accuracy, high performance
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.
Application:
Mainly used in machining for hardened steelsHRC=48°~65°, cast irons and sintered irons as well as powder metallurgy components. Such as Gear, Transmission, Brake disks etc.
