Specializing in Tooth By Tooth Induction Hardening

We have unique induction hardening capabilities among commercial heat treaters. Specializing in gear tooth by tooth induction hardening, AMT is a valued source for gear manufacturers. Specific capabilities include:

  • Spur and helical gears up to 15 tons
  • Spur and helical gears up to 220″OD
  • Spur and helical shafts up to 160″OAL
  • Face lengths up to 45″
  • Bevel Gears up to 65″OD
  • Internal gears up to 120″OD
  • Sprockets of any size
  • Racks up to 72″OAL
  • Fine pitch induction hardening of 5-10 DP spur and helical gears
  • Shafts and pins up to 85″OAL and 12″OD

We have tooth by tooth gear induction hardening capacity that is unmatched among commercial heat treaters. Our versatile CNC controlled equipment includes:

  • Five Ajax coarse pitch hardening machines (.5DP-5DP)
  • Three external Natco submerged process machines (5DP-10DP)
  • Two Internal Natco submerged process machines (1DP-8DP)

A mix of solid state, motor generator and radio frequency power supplies allow hardening of a wide variety of parts to case depths up to .250”. Our in house machine shop provides quick tooling for any production runs.
