EFD Induction USA, Madison Heights, Mich., reports that a major U.S. tier-one automotive supplier recently ordered an EFD Induction Rotary Table (HardLine RT 550) hardening system for treating sun gears, and a vertical scanner system (HardLine VM 1000) for hardening output shafts. The Sinac power source delivers a constant power factor of 0.95 at all power levels.
HardLine is EFD Induction’s family of systems for surface and through-hardening, with equipment available to handle everything from small gears with complex geometries, up to the giant slewing rings used in modern wind turbines. The vertical scanners support a range of optional subsystems, including automated loading/unloading solutions, indexing tables with unlimited position control, double tailstocks and centers for the simultaneous hardening of two workpieces, and a HF/MF chuck connection for quick changeovers between high and medium frequencies. The hardening system can also be paired with an integrated or separate tempering station.
