PURPOSE

 

The UFD 140 N Portal Wheel Lathe is a CNC double-saddle special-purpose lathe designed for reprofiling of wheels used in rail vehicles. Thanks to optimised design features and high power of main drive the machine tool ensures productive machining of solid (monoblock) wheels and wheels with tyres of both used and new wheelsets. The friction roller drive allows to avoid notches on wheel surface which may expand to the fatigue damages of the wheels.

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

The wheelset is rolled onto the built-in wheelset elevator along rails and automatically centred and clamped between the centres and the friction drive rollers; three rollers are attached to each wheel.

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 four AC motors of continuously variable rotation rates and digitally controlled in master / slave system.

The UFD 140 N Portal Wheel Lathe 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.
  • Wheel rim outer facing.
  • Turning of limit machining groove.
  • Turning of wheel centre.
  • Axle-mounted brake disc facing.
  • Wheel-mounted brake disc facing.

 

MAIN FEATURES

 

  • Major body elements made as extremely rigid, heavily ribbed box-type high-grade iron castings in the form of portal guaranteeing the best dumping of vibrations produced during cutting process and excellent chip evacuation.
  • Main drive from four friction rollers individually powered by 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 (laser-based measurement as option).
  • 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.
  • Available multi track gauge version.
