New Single Coil Dual Frequency Induction Hardening System For Gears

Inductoheat, Inc., has designed, built and shipped a NEW Single Coil Dual Frequency Induction Gear Hardening System to a leading supplier of automotive engine and powertrain components. This machine was designed specifically for heat treating a medium size gears.

This Single Coil Dual Frequency Induction Gear Hardening System is rugged and can be used for high-volume, single shot induction hardening of internal wide-face, gear-like components. A distinct feature of this induction system is the heating and quenching cycles dramatically minimize distortion of parts and provide a superior hardness pattern with favorable distribution of residual stresses.

The total power exceeds 1,200kW comprising a medium frequency (10kHz) and high frequency (120kHz - 400kHz) power modules working not just simultaneously, but in any sequence desirable to optimize properties of the gears heat-treated using this unique technology. Total heat time can be minimized to about 1.5 seconds.

Utilization of the standard platforms for manufacturing medium and high frequency modules substantially reduces the cost in contrast with other systems.

Allen Bradley controls with PC touch screen operator interface offers superior process control and monitoring capabilities assuring the highest quality and repeatability of any induction system. Integrated closed-loop, water recirculation system reuses water for quenching and cooling.

Other features include:

• High-speed servo spindle drive for precise control of rotation speed during heat and quench.

• Heavy-duty aluminum splash door with safety interlock switch and light curtains.

• Robust system components with advanced QA, precise position control and safety measures.
