The standard shape of MORE® PCBN Cutting Tool Blanks is round. Other shapes, such as segment, rectangle, triangle, square, semi-circle and so on, can also be customized per customers requirements.
PCBN is widely used in processing of cast iron, hardened steel, powder metallurgy materials and Ni-Co heat-resistant alloy materials,
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.
