Full Automatic Wheels Steel CNC Induction Quenching Machine Tool

It is an automated CNC induction heating and quenching system designed primarily for hardening steel parts such as wheels. It uses high-frequency induction heating with rapid quenching to change surface hardness and improve wear resistance while offering CNC-controlled process repeatability.

A solid-state RF power supply drives an inductor (a copper coil). The workpiece placed inside the coil acts as the transformer's secondary and eddy currents are induced in the metal. These eddy currents produce rapid, localized heating. The system then applies quenching to harden the heated zone.

Model: JLC-120KW. Power: 120 kW. Voltage: 3-phase 380 V, 50/60 Hz. Max input current: 195 A. Oscillating frequency: 10–30 kHz. Duty cycle: 100%. Cable length: 2–6 meters. Cooling water: >0.2 MPa and >6 L/min, temperature ≤40°C.

The system requires a stable cooling water supply with pressure greater than 0.2 MPa, flow over 6 L/min, and water temperature at or below 40°C. Adequate filtration and gradual flow control are recommended to prevent cavitation and protect the power electronics.

The machine is optimized for ferrous materials (carbon and alloy steels) that respond to induction hardening and quenching. It can process wheels and similar steel components. Nonferrous metals (aluminum, copper) heat differently and are generally not suitable for quench hardening with this system.

Frequency controls the heating penetration depth: higher frequencies (toward 30 kHz) produce shallower, surface-focused heating for thin case depths; lower frequencies (toward 10 kHz) penetrate deeper. The machine's 10–30 kHz range covers many typical wheel and component case-hardening requirements.

Yes. It uses CNC control for repeatable positioning and process sequencing. The RF generator employs MOS/IGBT frequency-conversion tracking and supports automatic frequency tracking, constant-current and constant-power control, and integration with temperature feedback for closed-loop operation.

The system supports infrared temperature measurement (optional/available) for automatic temperature feedback and closed-loop control, improving heating accuracy and reducing the need for manual adjustments.

The unit includes multiple fault protections such as over-current, over-voltage, water-shortage, and phase-missing detection. Because it uses solid-state medium-voltage electronics rather than very-high-voltage equipment, it reduces some electrical hazards, but proper grounding and safety measures are still required.

Prepare a stable 3-phase 380 V power supply sized for the unit (up to the listed max current), a chilled/circulating water system meeting the flow and pressure specs, adequate ventilation, a leveled and load-bearing floor area, and proper grounding. Exact footprint and anchoring depend on the chosen configuration—confirm with the supplier.

Regular maintenance includes checking and maintaining cooling water quality and flow, inspecting coils and connectors for wear, cleaning filters and vents, verifying cable and grounding integrity, and periodic inspection/testing of power electronics modules (IGBT/MOS). Follow the manufacturer's maintenance schedule for parts replacement and calibration.

Typical faults include over-current, over-voltage, water shortage, and phase missing. Basic checks: verify cooling water flow/temperature and pressure, confirm all three-phase power present and within spec, inspect coil and bus connections for shorts/loose contacts, and restart the system per manual. If faults persist, consult authorized service.

Maximum part size and weight depend on the chosen coil, chuck/fixture, and CNC handling configuration rather than the generator alone. Contact the supplier with your specific part dimensions and mass so they can recommend or design the appropriate coil, fixtures, and automation package.

Yes. The CNC and control architecture, along with automatic frequency tracking and temperature feedback, make the system suitable for integration into automated production lines. PLC/communication interfaces and custom fixturing are typically provided to match line control protocols—discuss integration requirements with the manufacturer.

Service, commissioning, operator training, and warranty terms vary by supplier and region. Contact the manufacturer or authorized dealer for details on warranty coverage, available training programs, spare parts packages, and onsite commissioning/support options.
