EFD Induction USA has recently won major orders from two American tier-one automotive suppliers. The orders involve EFD Induction HardLine-type induction scanning systems for the hardening of sun gears and output shafts. Each system comprises an induction scanner, a power source, and various optional features.
The first order comprises 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 second order is for two vertical scanner systems, a HardLine VS 300 for hardening sun gears and a HardLine VL 1000 for treating shafts.
All the systems are powered by EFD Induction Sinac power sources and feature CNC-based control systems. Each machine also features a closed-loop cooling system.
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 and unloading solutions, indexing tables with unlimited position control, double tailstocks and centers for the simultaneous hardening of two workpieces, and an 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.
