The UFB 125 N Above Floor 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 wheelsets can be provided 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 friction drive rollers - three rollers are attached to each wheel.
The main drive is powered by six AC motors of infinitely 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;
Versatile equipment and wide programming capabilities facilitate easy machining of unusual wheel profiles;
