HardLine M – Modular Vertical Hardening Machine
A new-generation modular vertical induction hardening system offering maximum flexibility, Industry 4.0 readiness, and suitability for a wide range of
HardLine – Vertical Heat Treatment Machines (VS / VM / VL / VXL)
HardLine vertical heat treatment machines by ENRX provide highly efficient, reliable, and automated induction hardening for a wide variety of workpieces. these systems reduce capital and operating costs thanks to their versatility, CNC precision, and advanced process control.
The machine types include:
- • VS – Compact models for workpieces up to 300 mm, suitable for small to medium production volumes .
- • VM – The most popular system, supporting components up to 400 kg such as CV joints, camshafts, axle shafts.
- • VL – Designed for large and heavy components up to 2,000 mm and 600 kg, compatible with CNC and robotic handling .
- • VXL – For extremely large and heavy parts. Features reinforced spindle, high-power output carriage, optional mobile spindle for large gears.
All systems are powered by SINAC induction generators, available in serial or parallel compensated versions. Multi-frequency SINAC systems can deliver two frequencies simultaneously for optimal hardening of complex shapes .
- • CNC-based control with absolute encoders
- • Automated loading/unloading options for maximum throughput
- • Programmable heating and quenching cycles
- • Indexing tables with static/rotating/single/double station options
- • HF/MF chuck connection enabling multi-frequency operations
- • Double tailstock options for simultaneous processing
- • Curved-disc hardening device for complex geometries
- • Closed-loop cooling system on all models
- • Compatible with robotic handling
As highlighted in the catalogue:
