DPL - Portal Lathe

Portal wheel lathes for machining wheelsets
DPL portal lathe machine DANOBAT
DPL portal lathe machine DANOBAT

Portal lathes have been designed and manufactured specifically for machining wheelsets. Among others, the following requirements have been taken into account for the design of the machine:

  • High material removal capacity.
  • High rigidity and excellent damping properties.
  • Axle box or centre clamping to eliminate wheel marking.
  • No need for additional lifting tools.
  • Easy chip removal.
  • Continuous contact measuring system for wheels and brake discs.
  • Wheelsets with fully assembled gearboxes can be machined.
