Function
The U2000-400 is suitable for turning the treads up to the crown of the wheel flange and the back of the wheel flange, reprofiling and partial reprofiling of wheelsets, machining the inner and outer wheel faces, reprofiling wheelsets single-sided, machining shaft brake disks and / or wheel brake disks and other options according to technical agreement.
The U2000-400 is operated via a central control panel, which provides optimum access to all machine functions in a suitable working position. At the same time, the operator is safely protected against flying chips during machining. The integrated automatic machining system relieves the operator and ensures simple control.
For simultaneous machining of wheelsets in bogies with mechanically uncoupled axles, a tandem version U2000-400D is also available.

We were guests at the Karlsruhe transport company and took a look behind the scenes. This is where our U2000-400 underfloor machine is used for machining wheelsets for streetcars. The modern underfloor wheelset turning machine not only meets all current working and precision requirements, but its overall design is also geared towards future developments. It represents the current state of the art in wheelset machining technology and also ensures efficient and precise maintenance and servicing of the fleet at Karlsruhe's public transportation company with several machines in operation.
