PCBN Cutting Tool Blanks

PCBN blanks for cutting tools is a kind of compound ultra hard material sintered by polycrystalline CBN and carbide alloy under the condition of ultra-high pressure and high temperature.

 

characteristic :

1.hardness,wear-resistance and thermal stability of CBN

2.impact resistance toughness of carbide alloy

3.fast cutting and high precision

 

 

Application:

Moresuperhard PCBN is ideal ideal material for cutting processing of ferrous metal and nonferrous metal with high hardness, such as harden steel, pearlitic gray cast iron, high temperature alloy, high-speed steel, hard facing alloys, Ni-Cr alloy, powder metallurgy metals. PCBN is typically used to machine brake discs, engine blocks, engine cylinder liners, brake drums, flywheels, valve seats and guides, gears, mold and die parts, etc.
