An EFD Induction HardLine VL 1000, similar to one recently ordered by a major US tier-one automotive supplier. The cabinet on the right contains the ‘Sinac’ power source. Also from EFD Induction, this generator delivers a constant power factor of 0.95 at all power levels.

Awarded orders for induction scanners to harden sun gears and output shafts

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.

22.03.15

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 supports 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, 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.
