Features
Advanced Wheel-Turning Machine Features
- Versatile Operation: One machine is fixed while the other is moveable, allowing easy accommodation of varying wheelbases of bogies.
- Shared Rail System: Both machines operate on a common rail system, with individual hydraulic and pneumatic systems, ensuring flexibility and efficiency.
- Independent Functionality: Each machine can work individually, enabling the profiling of a single wheel set when required.
- Robust Construction: Rigid cast iron basements provide solid support for both the mobile and fixed machines, ensuring stability during operations.

- Synchronized and De-synchronized Mode: All four drive rollers of both machines rise in synchronized mode with displacement feedback during lifting and centering of the wheel set. In de-synchronized follow-up mode during wheel profile turning, the rollers maintain positive contact even on worn wheels.
- Slippage Detection: The system includes a feature to detect slippage between the drive rollers and the wheel set, enhancing reliability.
- Dual CNC Tool Carriages: Each machine is equipped with two CNC tool carriages, enabling simultaneous measuring and machining of both wheels in a wheel set.
- High-Precision Mechanics: Hardened and ground guideways, along with preloaded ball screws, ensure consistently high accuracy.
- Quick-Change Tooling: Equipped with CAPTO/KM LOCK quick-change tooling for rapid wheel profiling and brake disk machining, minimizing downtime.
Integrated Measurement System: Each CNC tool carriage comes with a proven wheel profile and diameter measuring unit for pre- and post-machining measurement, ensuring precision throughout the process.
Benefits
Maximizing Efficiency with Tandem UFWL Wheel Profiling
- Significant Time Reduction: Our advanced wheel profiling system reduces the re-profiling time for coaches by 50% and for locomotives by 33%, ensuring quicker turnaround and higher availability for revenue service.
