Hard surface processing

   So-called hard surface process is collected surface build-up welding,spray welding, spraying, aser cladding technology,Surface heat treatment or nitriding process,etc., surface of the workpiece to obtain higher hardness, Wear-resisting corrosion resistance, impact resistance, etc. Aiming at hard surface process, HALNN superhard developed a non metal adhesive cubic boron nitride cutting tools BN-S20 model number, coarse and fine processing can be. Specific processing schemes are as follows.
1.Halnn superhard non-metallic binder CBN cutting tools BN-S20 model number processing build-up welding roller solution:

Processing Materials: Cobalt-based alloys;
Processing parts: build-up welding roller(hardness HRC45-55);
Cutting tools model: BN-S20;
Processing procedure: External turning;
Cutting parameters: ap=2.5mm,Fr=0.12mm/r,Vc=65m/min;
Processing type: Wet cutting
Processing effect: Compared to carbide cutting tools: The cutting speed of our cutting tools is higher 4.5 times than carbide cutting tools, cutting tool life is 12 times of carbide cutting tools. 
2.Halnn superhard non-metallic binder CBN cutting tools BN-S20 model number processing Spray welding parts solution:

Processing parts: Spray welding parts;
Processing materials: Nickel-based alloy powder spray welding parts;
Hardness:HRC50
Cutting tools model: BN-S20;
Processing procedure: External turning,Wet cutting
Cutting parameters: ap=1.5mm,Fr=0.15mm/r,Vc=145m/min;
Processing effect: HALNN BN-S20 model number and a European brand PCBN cutting tools compared: cutting speed in the same situation, HALNN BN-S20 model number cutting tool life is 2 times of PCBN cutting tools life, and cutting tool flank is normal wear, rather than collapse damage, rupture.
3.Halnn superhard non-metallic binder CBN cutting tools BN-S20 model number processing spraying the workpiece solution:

Processing Parts: Cobalt base spare parts, spraying thickness of 2 mm;
Processing Materials: Cobalt-based alloy powder spraying roller;
Hardness:HRC60
Cutting tools model: BN-S20;
Roughing cutting parameters: Vc=70m/min;Fr=0.7-0.8mm/r;ap=1.7mm;
Finishing cutting parameters: Vc=120m/min;Fr=0.25mm/r;
Processing effect: HALNN BN-S20 model number and carbide cutting tools compared: The cutting speed is carbide cutting tools 6 times, Depth of cut is carbide cutting tools 3 times, not only to improve the processing efficiency, but also reduce processing costs.

4.Halnn superhard non-metallic binder CBN cutting tools BN-S20 model number processing Laser cladding workpiece solution:

Processing parts: Hydraulic prop;
Processing Marterials: 27SiMn(The surface hardness after laser cladding is around HRC55);
Processing procedure: Semi-finishing and finishing;
Cutting tools model: BN-S20 CNMN120712;
Cutting parameters: ap=1mm,Fr=0,15mm/r,Vc=145m/min;
Processing type: Dry cutting
Processing effect: Compared to carbide cutting tools: Not only improve processing efficiency, reduce production time, saving processing costs, and surface finish to Ra0.4, long cutting tool life.
