Dual Station CNC Induction Hardening Machine Shipped

Delivery of Induction Hardening Machine for Outer Race to Russian Customer

Recently, the induction hardening machine for outer race customized for our Russian customer successfully passed strict acceptance tests and has now been carefully packed and shipped. This marks another successful delivery of advanced heat treatment equipment and reflects our firm progress in expanding into the international market.

Dual-Station Design for Efficient Hardening

The machine adopts a dual-station through-type structure, consisting of an inner cavity hardening station and a spline hardening station:

Inner cavity hardening station: Equipped with a three-jaw hollow chuck to clamp the workpiece shank or upper outer circle. During hardening, the workpiece rotates while the inductor remains fixed, ensuring stable and uniform energy transfer.

Spline and shaft hardening station: The workpiece rotates while the lower support positions it via the inner bore slope and end face, with the upper center applying pressure. This ensures high precision and reliability, particularly for complex outer race components.

The dual-station configuration not only improves production efficiency but also meets the hardening requirements of different parts of the workpiece, reducing changeover time and labor involvement.

Intelligent Control and Process Traceability

The machine is equipped with the Siemens 828D CNC control system, enabling fully automatic execution of hardening programs and minimizing human error. It also integrates a process data monitoring system for real-time monitoring, recording, storage, and printing of process parameters. This ensures full traceability and helps customers establish standardized quality systems and optimize their heat treatment processes.

Advanced Cooling System for Performance and Sustainability

The machine features a separated quenching fluid tank design, where the tank is independent of the machine bed. Quenching fluid is circulated back to the filtering system via a dedicated pump for efficient reuse. This design extends coolant life, ensures process stability, and supports environmental sustainability.

Additionally, the equipment is equipped with an internal circulation cooling system (HKSL-350) for machine cooling. Using softened or distilled water, the system includes one stainless steel water tank, one main pump, and one booster pump. All pipelines are made of 304 stainless steel for corrosion resistance and durability. The digital temperature control system allows precise water temperature settings (25–35°C), while the inductor benefits from high-pressure cooling. This ensures stable performance even under heavy-duty operation, extending equipment life and reducing maintenance costs.
