Induction Brazing Carbide File
Objective:Ā Induction Brazing carbideĀ rotary file assemblies with uniform concentricity in an aerospace application
Material ā¢ Carbide blank ā¢ High speed steel shank ā¢ Temperature indicating paint ā¢ Braze shim and black flux
Temperature 1400Ā°F (760Ā°C)
Frequency 550 kHz
Equipment:Ā DW-UHF-4.5kw induction heating system, equipped with a remote heat station containing two 0.33 Ī¼F capacitors (total 0.66 Ī¼F) An induction heating coil designed and developed specifically for this application.
Process A multi-turn helical coil is used. The part is heated to determine the time required to reach the desired temperature and required heat pattern. It takes approximately 30 – 45 seconds to reach 1400Ā°F (760Ā°C) depending on the various part sizes. Flux is applied to the entire part. A braze shim is sandwiched between the steel shank and carbide.Ā Induction heating powerĀ is applied until the braze flows. With proper fixturing, concentricity of the part can be achieved.
Results/Benefits ā¢ Repeatable, consistent precise heat.
