    The Vacuum Welding Process of Super-hard Tools

    Super-hard cutting tools mainly refer to cutting tools made of diamond or cubic boron nitride. At present, more materials are used: single crystal diamond, PCD polycrystalline diamond, integral CBN, PCBN composite sheet. Vacuum welding of super-hard tools refers to the completion of the brazing action between the super-hard tool base and the cutter head by heating in a vacuum state. Like flame brazing and high-frequency induction brazing, the ultimate goal of vacuum welding is to make the molten solder flow evenly to all parts of the weld under the action of the capillary pipette to achieve the best welding effect. Therefore, for the super-hard tool products suitable for vacuum welding, selecting suitable solder, proper pre-welding treatment, and correct welding process can make full use of the advantages of vacuum welding and ensure the performance of super-hard tool products.
