BASIC TECHNICAL SPECIFICATIONS

 

Range of wheel tread diameters: 770 to 1,200 mm
Maximum wheelset weight: 4.5 × 10 kN

 

PURPOSE

 

The UDA 125 N Portal Wheel Lathe is a CNC double-saddle special-purpose lathe designed for reprofiling of wheels and brake discs used in rail vehicles. The machine tool ensures productive machining of solid (monoblock) wheels and wheels with tyres of both used and new wheelsets.

The machine tool is provided with axial wheelset clamping system. It is also possible to apply radial clamping system.

The wheelsets can be equipped with outboard axle boxes, gears installed between the wheels and brake discs.

The wheelset is rolled onto the built-in wheelset elevator along rails, automatically centred and clamped between the centres and the driving dogs installed on spindle face plates.

The machine tool main structure is made in the form of a portal enabling wheelsets unloading to its rear side in roll-through flow. It is also possible to unload the wheelsets to the machine front side.

The main drive is powered by two AC motors of infinitely variable rotation rates and digitally controlled in master / slave system.

The UDA 125 N Portal Wheel Lathe with axial wheelset clamping system is capable of performing the following operations:

  • Turning of wheel profile according to technological program;
  • Wheel rim inner facing;
  • Turning of tyre in order to remove retaining ring;
  • Axle-mounted brake disc facing.

 

MAIN FEATURES

 

  • The machine main structure made as a single-piece extremely rigid, heavily ribbed box-type high-grade iron casting in the form of portal guaranteeing the best dumping of vibrations produced during cutting process and excellent chip evacuation;
  • Main drive powered by two AC motors of continuously variable rotation rates and digitally controlled in master / slave system;
  • Automatic and reliable profile wear measurement using touch-type measuring heads;
  • Productive machining of narrowed (economical) wheel profiles;
  • Operation in roll-though or roll-in roll-out system;
  • Versatile equipment and wide programming capabilities facilitate easy machining of unusual wheel profiles.
