Induction brazing of carbide inserts on wood drilling bits extends their wearability and improves their effectiveness.
Innovative induction brazing technology has significantly improved the performance of woodworking tools, especially to the carbide inserts on the cutting tips. This solution has led to a significant extension of tool life, revolutionizing the sector.
Brazing of metal inserts on wood drilling bits
In the constant search for improvements in the performance of woodworking tools, induction brazing technology has proven to be an innovative and highly effective solution. In particular, the application of this technique to carbide inserts on wood drills has revolutionized the industry, leading to a significant extension of the lifespan of these tools.
Induction brazing offers precise temperature control during the process of fusing the carbide inserts onto the tips. This precision prevents overheating and thermal damage to the base material, preserving the structural strength and durability of the tool. The result is a woodworking tool that not only maintains its cutting performance, but significantly improves it.
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.
