Note: Braze a carbide tip to steel cutting tool
Objective:
Braze a carbide tip to a 4140 steel cutting tool
End Product:
Cutting tool
Equipment:
Ambrell 10 kW induction heating system, equipped with a remote workhead containing two 1.5µF capacitors for a total of 0.75µF An induction heating coil designed and developed specifically for this application.
Materials:
Carbide Isograde C2 & C5 tips 4140 circular steel cutter flux silver braze shim
Temperature:
1400 ºF (760 ºC)
Frequency:
290 kHz
Testing:
A split helical coil is used to heat the carbide & circular steel cutter evenly for the brazing application. The circular steel cutter is placed in a vise and the carbide and braze shim are placed onto the tooth. The assembly is heated for 5 seconds to braze the carbide to the circular steel cutter. The circular steel cutter is rotated in the vise & each carbide tip is brazed separately without effecting the previous braze.
Benefits:
-
Rapid, localized heat applied only to tip being brazed, will not effect previous brazes on the assembly
-
Neat and clean joints
-
Produces high quality repeatable parts
