Advanced techniques for the recovery and reuse of hard Metal Tools using induction debrazing.
Debrazing is a crucial process for recovering worn tools, allowing for the restoration of their original conditions and extending their useful life. This method is particularly important in the industrial sector, where the reuse of tools leads to significant economic savings and sustainability.
Debrazing and brazing of PCD (Polycrystalline Diamond) to cutting tools represent a common process for the repair and production of tools.
Cutting tools are heated to the brazing temperature to remove the worn insert and the old alloy.

Description of the process:
In this application, a Platinum HF6 generator (high frequency – 6 kW) was utilized, with power modulation ranging from 60% to 100%. The heating time varied from 9 to 32 seconds, depending on the size of the tools, and employed…..
Here is an example process for a drill with a diameter of 9 mm and a carbide insert.
Process Details:
Auxiliary Materials:
Brazing Material: 40% silver alloy
Flux: in paste for high temperatures
Process Description:
The process begins with the careful placement of the 9mm bits and tips inside the loops of the inductor. The inductor allows uniform and controlled heating of the brazing area with power generated by the Platinum HF6 generator system with setting of 50% of power.
The temperature is brought and maintained at 750°C with a program lasting 12 seconds, optimizing the melting and penetration of the alloy by capillarity. The thermal imaging camera, with its precise reading capability, ensures that the process remains within critical parameters.
By carefully controlling the heat, the risk of damaging the base material during the brazing process is reduced. This is especially important when working with steel tools that need to maintain their strength and hardness.
