Underfloor Wheel Lathe

Railway equipment for predictive maintenance of rolling surfaces.

Underfloor wheel lathes are machine tools specifically designed for corrective maintenance of railway rolling surfaces and brake discs. No need to dismantle the train axles. Designed to regenerate the wheel profiles subject to normal wear and deformation caused by the transit of the wheels on the track.
