KOLTECH TUU 1250 CNC above floor wheel lathe

KOLTECH TUU 1250 CNC above floor wheel lathe was manufactured in Poland in 2007. The wheel lathe is a special-purpose machine designed for the turning process of the running profile of wheelsets used in various types of rail vehicles. The lathe uses high-end components to guarantee efficient and precise machining of both used and new wheelsets for the railway industry. The solidly constructed structure with friction drive allows a wheelset with a maximum weight of 4 tonnes to be fed into and out of the machine from hall level.

The TUU1250 machine performs the following operations:
– reconditioning of the wheel profile of used wheelsets,
– turning of the wheel profiles of new wheelsets,
– turning of the clamping ring of the wheelset wheels,
– facing of the inner and outer face surfaces of the wheels,
– facing of the active surfaces of brake discs, installed on the wheelsets on the axle or in the wheel hub with the use of the optional equipment.
