Underfloor Wheel Lathe
Feb 20, 2017

The  Underfloor Wheel Lathe  is a pit-mounted CNC wheel lathe that is easy to use and maintain. Its design represents the highest level of wheel set machining technology. The machine's high degree of use, precision, long service life, and minimal maintenance costs guarantee ideal cost-effectiveness. The  Underfloor Wheel Lathe utilizes fully automatic positioning, machining, and measuring processes. The turning technology combined with CNC control and related set-up automation makes it easy to change from one wheel profile to the next if required. The machine is available in single and tandem machine versions. The  Underfloor Wheel Lathe is a tandem underfloor wheel lathe capable of machining two wheel sets simultaneously.

The machine is arranged in a pit. The wheel sets to be re-profiled are brought into the machine via the supply rails (if still attached to the vehicle) or by crane (if removed from the vehicle). For re-profiling, the wheel sets are driven by friction rollers pushing on the running surfaces. The high dynamic stiffness of clamped wheel sets required to produce the highest possible machining precision is guaranteed by the radial centering of the axle bearing box. Lateral positioning of the wheel set is executed by the use of axial guide rollers. The machine is operated from a central control panel, which enables the operator to have constant access to all machine functions. During machining, the operator is protected from flying chips. The automated machining takes most of the work from the operator's hands, making the machine easy to operate.
