The Hegenscheidt Portal Wheel Lathe (HP-165) is a high production CNC wheel lathe that is easy to operate and maintain. Its portal design allows for wheel sets to roll through the lathe on shop rails. The mechanical elements and drive system are designed for cutting performance up to 32 mm² / 1.25 in² per tool post. This allows for a short floor-to-floor time for re-profiling, even for extreme wheel wear conditions.
The lathe’s working area is fully enclosed, protecting the operator from chips. The turning tool posts and tool post guides are located above the wheel set. The wheel set drivers consist of a faceplate designed as a chuck and a sleeve on each side. Every faceplate is driven via its own, continuously variable motor with gearbox. The large center sleeves with integrated center point clamping are guided free of play and clamp the wheel set axially. The lathe includes automatic measuring probes that communicate measurement results directly to the CNC-based control system, ensuring an accurate cut where the least amount of metal is removed. The control system is accessed via a railway-specific graphical user interface that requires no programming knowledge on the part of the operator.
