Rafamet UGE 180 Underfloor wheel lathe

The Rafamet UGE 180 N Underfloor Wheel Lathe is CNC double saddle special purpose lathe designed to machine wheelsets, used in light rail transit system vehicles trams, metro, suburban trains, with or without dismantling them from the vehicle. The machine tool is also available in the tandem configuration capable of machining two
wheelsets of the same bogie at the same time. 

lnstalled in a pit type foundation below the traffic rails and operating in roll through system
Reconditioning of wheel profiles and brake discs mounted on vehicles significantly shortens the shutdown time of the rolling stock and thus increases efficiency of its exploitation. Unique system of wheelset lifting and driving realized by four independent drives ensures flexible pressure of rollers and constant contact between driving rollers and wheels. Automatic and reliable profile wear measurement using touch type or laser based system. Versatile equipment and wide programming options guarantee precise machining of even
unusual wheel profiles
