2 UGE 180 N – tandem underfloor wheel lathe

Double Underfloor Wheel Lathe with axle load up to 18/30 tonnes

BASIC TECHNICAL SPECIFICATIONS

PURPOSE

The 2 UGE 180 N Underfloor Wheel Lathe is composed of two single CNC double-saddle special-purpose lathes, designed for machining of wheelsets used in rail vehicles. Its main application is reconditioning of wheel profiles and facing of brake discs of two wheelsets of light rail transit system vehicles (trams, metro, commuter) without dismantling them from the vehicles.
This significantly shortens the shutdown time of vehicles and thus increases the efficiency of their exploitation. Reprofiling of single wheelsets or bogies dismantled from vehicles is also possible.

The machine is installed on a pit-type foundation (below the traffic rails), which ensures its operation in a roll-through system.

The 2 UGE 180 N Underfloor Wheel Lathe is capable of performing the following operations:

• Turning of wheel profile according to technological program;
• Wheel rim inner facing;
• Wheel rim outer facing;
• Turning of limit machining groove;
• Axle-mounted brake discs facing;
• Wheel-mounted brake discs facing.

 The machine tool is also available in a single configuration - UGE 180 N, which is capable of machining only one wheelset.

MAIN FEATURES

• Compact and extremely rigid design based on a single-piece (monolith) high-grade grey iron casting, which guarantees both the machine tool high geometrical stability and the most efficient vibration damping;
• Unique system of wheelset lifting and driving realized by four independent drives ensuring flexible pressure of rollers and constant contact between driving rollers and wheels;
• Automatic and reliable profile wear measurement using touch-type measuring heads (laser-based measurement as option);
• Productive machining of narrowed (economical) profiles;
• Versatile equipment and wide programming capabilities facilitate easy machining of unusual wheel profiles.
