Maximum flexibility at low cost
EFD Induction is proud to announce a new generation of vertical hardening machines: The Hard-Line M - a modular hardening machine designed for the future.
Vertical induction hardening machines
Our versatile vertical machines cover everything from manually loaded to fully automated in-line systems. Different models are available for hardening workpieces ranging from small components to large dimension rollers.HardLine VS
Specially designed for workpieces up to 300 mm in length, the VS system is ideal for small to medium production volumes. Despite its compact size, the VS is extremely versatile and is available in numerous configurations. Each VS machine can be fitted with a turntable for fast and easy loading/unloading.
HardLine VM
Our most popular vertical hardening system, the HardLine VM is capable of hardening components up to a maximum of 400 kg. A key benefit of the HardLine VM is its versatility, with a single system able to handle everything from CV joints to camshafts and axle shafts.
HardLine VL
The VL machine is designed specifically for large and heavy components up to a maximum length of 2,000 mm and a weight of 600 kg. As with all HardLine vertical machines, the VL is compatible with CNC controls and robotic handling.
HardLine VXL
HardLine VXL is a hardening machine built specifically for very heavy and/or large parts. To let the machine handle large components, the VXL features a special, reinforced spindle and a high-power output carriage. The VXL can also be fitted with a mobile spindle, making the machine ideal for hardening large gears.
HardLine Vertical heat treatment machines
HardLine vertical induction hardening systems are available in four machine types, each one designed for a range of workpiece sizes: VS, VM, VL, VXL.
