The use of vacuum brazing heat resistance of the workpiece itself as a heat source

Currently, the general use of low-temperature silver brazing, induction brazing and heat diffusion welding of polycrystalline diamond cutters have not seen a vacuum brazed  cubic boron nitride teeth polyester products reported. Vacuum brazing is to use resistive heating of the workpiece itself as a heat source, the polycrystalline diamond layer is locally cooled, the Diamond blade of high-temperature brazing.  abrasive grinding analysis, wear testing and ultrasonic testing techniques for vacuum brazing process polycrystalline diamond cutting teeth were studied systematically. Test material selection YGl5 Carbide pillars and domestic polycrystalline diamond compact. Brazed polycrystalline diamond cutters test brazing in vacuum brazing machine homemade carried out.
