UGE 300/400 N – underfloor wheel lathe (3)

Underfloor Wheel Lathe with axle load up to 30/40 tonnes

BASIC TECHNICAL SPECIFICATIONS

PURPOSE

The UGE 300 N and UGE 400 N Underfloor Wheel Lathes are the CNC double-saddle special-purpose lathes, designed for the machining of wheelsets used in rail vehicles. Their main application is reconditioning of wheel profiles and brake discs of heavy rail vehicles (locomotives) without dismantling of wheelsets 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 machines are installed on a pit-type foundation (below the traffic rails), which ensures their operation in a roll-through system.

The UGE 300 N and UGE 400 N Underfloor Wheel Lathes are 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 tools are available in the tandem configuration - 2 UGE 300 N and 2 UGE 400 N, which is capable of machining two wheelsets of the same bogie.

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.
