SFD PCBN composite sheet, PCBN inserts, PCBN inserts overall! Supplying high-quality domestic PCBN whole piece overall CBN inserts mainly used for: rolls, brakes, brake drums, brake pads, slurry pumps, industrial pumps, diesel engines, cast iron, hardened steel, bearing steel, high chrome steel, carbide, powder metallurgy, hardening gears, ball screws and other Rockwell hardness (HRC45-90 °) between the high hardness of the metal roughing and semi-finishing; finish machining can be achieved Ra0.8 cutting capacity, impact strong, good wear life characteristics. SFD PCBN cutting tool used for ferrous sheet metal processing HRC45-65 such as: high-speed steel, bearing steel, cast iron, etc., are usually used to process the brakes, engine cylinders, brake drums, flywheels, valve seats / stalls, gearing and other abrasive. Workpiece surface finish can be achieved in the car instead of grinding, greatly improving the work efficiency, reduce production costs. SFD PCBN inserts by CB and BN large range of products consisting of: CB Series products feature a composite of polycrystalline cubic boron nitride layer and the carbide layer made good weldability. Good wear resistance to fracture strength of the high chemical stability, high precision machining the workpiece size consistency Application: Tell cutting BN Series Features cast iron metal powder metals and high-temperature alloy cast iron: the pure polycrystalline PCBN, no hard alloy substrate with good wear resistance on both sides can make the cutting edge, cost-effective high-temperature resistance No. excellent fracture resistance Application: gray cast iron cutting and grinding tell. Cold cast iron, cast iron and nickel-based cutting ductile cast iron. Segment PCBN PCBN superhard composite sheet is mainly used for cutting tools, PCBN superhard wear parts. Overall PCBN inserts: Direct for standard blade advantages: a more cutting edge, high utilization 2, Blade is monolithic, no excessive phase high impact strength 3, simple production process.
