PCBN inserts are compound super-hard material of polycrystalline cubic boron nitride layer and tungaten carbide sintered under ultra high pressure and high temperature.The hardness of PCBN is second only to diamond.

* Strong corrosion resistant, perform a good thermal stability and red-hardness

* CBN cutting tools have properties which resist chipping and cracking and provide uniform hardness and abrasion resistance in all directions. They may outperform conventional cutting tools by as much as 50 times.

* The high chemical stability allows for PCBN to be stable up to 1000° C and no reaction with Fe, Ni, CO etc

* Cutting hard and tough Materials . CBN cutting tools are so hard that they can efficiently machine steel with hardness of Rc 45 and above

* Easy grinding and EDM cutting. Uniform surface finish, surface finishes of less than 10 micron

Machining ferrous materials. Such as gray cast, cast iron, carbon steels, quenched steel, nickel and cobalt, other kinds of ferrous metal, etc

More SuperHard pcbn inserts are widely used in automotive, medical and aerospace machining industries. Such as

Shafts, gears, bearings, dies, molds

Clutch plates, brake rotors and drums, cylinder blocks, flywheels heads

Camshafts, valve bodies, impellers, casings, valve guides

Turbine blades, vanes, shrouds, housings, hip joints, pipe and liners, fuel rod

Valves seats, hydraulic pumps, cam lobes

Extrusion screws, barrels, turbine, case, housings, compressor hubs

* Other models types(RCGN ,RCGN ,SNGA ,SCMW,TNGA,CNGA,VNGA,VCGW,CCMW,TCMW CBN inserts) all available upon request. More SuperHard PCBN inserts tested well in European countries,Japan, and USA markets.
