Inductoheat, Inc. delivered an induction hardening and tempering system to a leading supplier of driveline components. The machine was designed specifically for hardening and tempering hub spindles and ball races. The system is comprised of a STATISCAN® IV unit for induction hardening and a STATISCAN® II unit for induction tempering. Allen-Bradley PLC controls with touch-screen HMI interface and process monitoring are utilized for process control and monitoring, assuring quality and repeatability. For system cooling and part quenching, an integrated closed-loop water recirculation system is included.

The part goes through an eight-station cycle using the following material-handling features: four pneumatic linear transfer 180-degree grippers, two pneumatic accept/reject arms and a continuous feed conveyor. There are two induction power supplies for this compact system. The hardening inverter is a UNIPOWER® UP12 power supply, which provides 200 kW @ 10 kHz, and a STATIPOWER® SP16 power supply offering 50 kW @ 10 kHz for the tempering portion.
