Fast Heating Speed Induction Hardening Machine for Gears, Rollers, Engine Parts, Aircraft, and Rockets.

It's a vertical induction hardening machine designed for rapid, localized hardening of shaft-type components and other parts such as gears, rollers, engine parts, aircraft and rocket components. It supports continuous scanning, simultaneous heating, segmented scanning and segmented simultaneous heating methods.

Typical applications include gear hardening, shaft hardening, sprocket and rail hardening, crankshaft quenching, steering rack and rack-and-pinion quenching, single-tooth hardening, welding/repair of cutting teeth and bits, internal hole hardening and other special-shaped ferrous parts.

Maximum workpiece length is 1000 mm, maximum diameter is 500 mm and maximum workpiece weight is 500 kg.

The machine is supplied with intermediate-frequency generators in the range of 100–600 kW, selectable to match the application and cycle requirements.

The machine provides very fast surface heating and hardening cycles—surfaces can be hardened in a very short period of time compared with traditional methods—enabling high throughput and reduced cycle times for many shaft and gear processes.

Yes. Hardened depth is adjustable and the system enables heating of limited or localized areas (teeth, faces, shoulders, internal bores) with precise control over the hardened zone.

Axis travels are X-axis up to 200 mm, Y-axis up to 200 mm and Z-axis 0–1000 mm, enabling accurate scanning and positioning for continuous or segmented hardening operations.

The equipment is primarily intended for ferrous materials such as carbon and alloy steels commonly used in gears, shafts and crankshafts. Non-ferrous metals (aluminum, copper, etc.) generally cannot be hardened by induction.

The system is designed to integrate with standard quenching media and quench delivery systems for rapid cooling after induction heating. Specific quench system configuration (spray, immersion, or localized quench) is selected based on the part geometry and process requirements.

Advantages include very fast surface heating, adjustable hardened depth, ability to harden limited areas at low cost and consistent high-quality results. The offered intermediate-frequency power supply is engineered for improved harmonic performance and efficiency versus some conventional intermediate-frequency units.

The machine is built to provide uniform, high-quality hardening with repeatable results when process parameters (power, scan speed, coil design and quench) are controlled and recipes are used for a given part.

Typical systems include servo or CNC control for axis motion and PLC/HMI interfaces for recipe management, power control and process monitoring. Custom automation options (robot loading/unloading, part handling) can be integrated to meet production needs.

Installation requires a high-power three-phase electrical supply sized to the selected generator (100–600 kW), adequate industrial cooling (water supply and return for power electronics and coils), and floor space for the machine, quench system and part handling. Exact requirements depend on configuration and should be confirmed with the supplier.

Standard provisions include guarding and interlocks, emergency stops, thermal and electrical protection for the power supply, and accessible service points. Routine maintenance typically covers coil inspection, cooling system checks and power supply preventive maintenance.

Yes. Coils, power rating, quench systems, fixturing and automation can be customized to suit special geometries, higher throughput requirements or specific process targets. Work with the manufacturer to define part-specific coil designs and process recipes.
