The solutions of diamond blade brazing machines mainly include two methods: induction brazing and vacuum brazing.
● Induction brazing
Induction brazing is a commonly used brazing method suitable for the welding of diamond blades. The specific steps are as follows:
Prepare silver solder paste: Apply silver solder paste evenly to the welding part of the diamond blade.
Induction heating: Use induction heating equipment to heat the blade to melt the silver solder paste and penetrate between the diamond and the substrate to form a strong bond.
Cooling and curing: After heating, the blade will cool and solidify to form a stable welding joint.
● Vacuum brazing
Vacuum brazing is brazing in a vacuum environment, which can effectively reduce the thermal damage of diamond:
Vacuum environment: In a vacuum chamber, the diamond blade and the substrate are placed in a vacuum environment.
Heating brazing: The brazing material is melted by heating and filled between the diamond and the substrate to form a strong bond.
Cooling and curing: Cooling and curing in a vacuum environment to ensure welding quality.
● Possible problems and solutions during welding
Thermal damage: Diamond is easily oxidized and graphitized at high temperatures, which affects the tool life. Solutions include using vacuum or inert environment for brazing, and selecting high-strength, crystal-complete diamond abrasives.
Unstable welding quality: This can be solved by optimizing brazing parameters and controlling heating temperature.
