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)
	One IPE Cheston internal gear hardening machine (2DP-5DP)

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.

The following are approximate case depths obtainable by induction hardening of gear teeth. It is assumed that the material is 1045 to 8660, and has been pre-heat treated to refine the grain structure. These are guidelines only; and in no way ensure that a particular case is adequate for the gear application.
