Note: Hardening of Steel Cam Assembly

Objective:

To harden the perimeter of ¼” thick steel cam assemblies 

End Product:

Steel cam assemblies

Equipment:

Ambrell 5 kW, induction heating system, equipped with a remote heat station containing one 1.0µF capacitor and an induction heating coil designed and developed specifically for this application

Materials:

¼” thick steel cam assemblies of varying geometries 

Temperature:

1650 ºF (900 °C)

Frequency:

177 kHz

Testing:

A two-turn helical coil is used to heat the cams. The heat time varies from 120-150 seconds. After heating, the parts are quenched in water. 

Benefits:

  • Uniform heating for uniform results

  • One coil can be used for many geometries

  • Consistent results from piece to piece
