What is CNC Above Floor Wheel Lathe?

A CNC above floor wheel lathe is a specialized machine used for the maintenance and repair of railway train wheels. It is called “above floor” because it is designed to be installed on the tracks, above the rails, rather than being positioned at ground level.

The CNC above floor wheel lathe utilizes computer numerical control (CNC) technology, which means it is automated and programmable, allowing for precise and efficient machining operations. The lathe is specifically designed to re-profile and turn the wheel treads, removing any imperfections and restoring them to their original shape.

Here are some key features and functions of a CNC above floor wheel lathe:

1. Wheel Turning: The primary function of the lathe is to turn the train wheels. It uses cutting tools to remove material from the wheel tread, eliminating any flat spots, wear, or irregularities that may have developed over time. This process helps to restore the wheel’s geometry, ensuring smooth and safe operation.
2. Precision Machining: The CNC technology enables high precision and accuracy in the machining process. The lathe can be programmed to follow specific profiles and dimensions, ensuring consistent and uniform results across multiple wheels.
3. Automatic Operation: Once the lathe is programmed with the desired specifications, it can operate automatically without constant manual intervention. This saves time and reduces the risk of human error.
4. Measurement and Inspection: The lathe may incorporate measurement and inspection systems to assess the condition of the wheel before and after turning. These systems can detect deviations from desired specifications and provide feedback for quality control purposes.
5. Dust Extraction: As the lathe cuts and removes material from the wheel tread, dust and debris are generated. A dust extraction system is often integrated into the lathe to minimize the release of particles into the environment and maintain a clean working area.

CNC above floor wheel lathes are commonly used in railway maintenance depots or specialized facilities dedicated to wheel maintenance. They play a vital role in ensuring the safety and reliability of train wheels by restoring their optimal shape and surface condition, thereby prolonging their lifespan and improving overall performance.
