Factory Tour

Experience the Strength Behind Every Railway Wheel

Founded in 2005, Tianjun Machinery is a national high-tech enterprise specializing in the manufacturing of railway wheels, axles, wheelsets, and bogies.

Our factory is located in Ma’anshan, Anhui Province, covering more than 30,000 square meters and integrating forging, heat treatment, machining, assembly, and quality testing under one roof.

Every wheel and axle produced at Tianjun reflects a commitment to precision, durability, and safety — trusted by railway systems in more than 50 countries.

Advanced Manufacturing Equipment

At Tianjun Machinery, we integrate modern manufacturing technology and intelligent control systems to achieve consistent quality across every stage — from forging and machining to heat treatment and final assembly.

Each production line is optimized for efficiency, precision, and reliability, ensuring that our products meet the highest international standards such as EN13262, UIC 510-5, and AAR M107/M208.

Quenching Line

Automated heat treatment line for railway wheels: Ensures uniform hardness and fatigue resistance of wheels

Automatic Processing Line

CNC-controlled machining line: Delivers precise dimensions and smooth finishes for railway wheels

Magnetic Particle Testing Machine

Non-destructive testing equipment: Detects surface cracks or defects in wheel and axle materials

Automatic Radial Ultrasonic Testing Machine (UT)

Ultrasonic testing system: Inspects internal structure for hidden flaws

Grinding Machine for Axles

CNC grinding equipment: Provides precise surface finishing for axles

Wheelset Press Machine

Automatic wheel-axle: Ensures perfect alignment and press-fit accuracy for wheelsets

Inspection & Testing Equipment

At Tianjun Machinery, quality is not an afterthought — it is built into every process.
Our in-house testing center is equipped with a full range of physical, chemical, and non-destructive inspection systems that guarantee each product meets or exceeds EN, AAR, UIC, IRS, and GOST standards.

All inspections are performed under the company’s ISO9001 quality management system, with traceable records for every wheel and axle.
