GH Induction Atmospheres built an innovative induction heating machine for a global automotive systems and components supplier. The new machine hardens and tempers two driveshafts for automotive starters every 16 seconds. The design employs dual vertical induction scanners with multiple power settings and scan speeds along each driveshaft, servo-controlled automated pick and place, and integrated process verification. Hardening is accomplished at a temperature of 1600°F (871°C), and the tempering cycle operates at 400°F (204°C). The machine is part of a larger, continuous driveshaft manufacturing process that includes previous machining and additional grinding.
