Specifications

The train wheels can be cut without separating carts from the train.

Product Description

Underfloor Wheel Lathes are Numerically Controlled Machine Tools for turning and reprofiling the tread bands of wheels mounted on axles and bogies, isolated or fitted on any type of railway vehicle, including trams. 

With these Wheel Lathes inspection and maintenance of vehicle wheels is facilitated and improved for the benefit of traffic safety and smooth running. They are distinguished by their precision, efficiency and easy use - thereby reducing the time vehicles are stationary in maintenance depots. 

 

Product Feature

Cutting and diameter measuring of train wheels are carried out automatically.

The train wheels can be cut without separating carts from the train.

Application

- CNC under-floor wheel lathe installed at pit under the rail is  to perform the form the automatic cutting of the wheel tread and flange's worn out on Computerized Numerical Control basis in order to prevent against noise, vibration and lowering of riding quality, caused from wheel's worn out, scratches, possible damage or abrasion by continuous operation on the rail. Other Information
Other Information

- The machine is cutting the wheel worn out without removal of cover and those that are worn out is driven by driving roller contact.
