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.

Polyetheretherketone PEEK has excellent comprehensive properties and can replace traditional materials such as metals and ceramics in many special fields. Moresuperhard has developed targeted grinding wheel formulas for the grinding of special engineering plastics such as PEEK, mainly electroplated grinding wheels, divided into rough grinding and fine grinding.
Diamond peripheral grinding wheels are used for peripheral grinding of PCD, CBN, carbide, ceramic, cermet and other indexable blades, flat blades, milling cutters, cutting blades, brazing blades, and machine clamp blades. At present, Moresuperhard peripheral grinding wheels have been successfully equipped with domestic and foreign mid-to-high-end peripheral grinding machines such as Hypertherm, Tiantong, Weize, WAIDA, EWAG, AGATHON, and WENDT, and have received unanimous praise from customers.
