Induction Quenching Machine

This series of induction quenching machines is a complete heat treatment system specifically designed for surface hardening of metal components. The system integrates a fully automatic digital IGBT variable-frequency induction heating power supply, quenching machine tool with auxiliary devices, CNC system, energy monitoring system, and induction coils. Ideal for gears, bearings, shafts, guide rails, sprockets, and various special-shaped parts, it is widely used in automotive, construction machinery, aerospace, wind power, and mold manufacturing industries.

1. Precise Hardening with Controllable Depth
Supports medium-frequency, super-audio, and high-frequency quenching. Hardened layer depth, hardness, and appearance meet international advanced standards. Closed-loop infrared temperature control ensures excellent hardness uniformity.

2. Fully Automatic CNC System
Equipped with Siemens servo control systems (e.g., 808/840 series) featuring "one-button operation" for the complete hardening cycle. Stores hundreds of process recipes for one-touch recall by workpiece number and name - ideal for multi-variety, small-batch production.

3. Intelligent Variable-Frequency Power Supply
Features 50kHz adaptive frequency range, automatically matching various induction coils without frequent main board adjustments. Exceptional voltage fluctuation resistance ensures processing quality remains unaffected by 360V-410V grid variations. Power factor >0.93 with no separate compensation device required.

4. Comprehensive Safety Protection
Equipped with ground fault protection that automatically cuts power when the workpiece contacts the inductor, protecting both the workpiece and equipment. IGBT ultra-fast protection and diode special protection technologies effectively extend equipment service life. Features ten intelligent protections: over-current, over-voltage, phase loss, water shortage, over-heat, and more.

5. Advanced Structural Design
Ball screw transmission and linear bearing guide rails deliver high precision, low friction, and long service life. Stainless steel splash guards and an integrated electrical cabinet with machine bed provide superior resistance to high-frequency electromagnetic interference.

6. Clean & Environmentally Friendly
No open flame, no smoke or fume emissions - significantly improves workshop working conditions and meets environmental and safety requirements.
