The UCB 125 Portal Wheel Lathe is a double-saddle special-purpose lathe designed for reprofiling of wheels and brake discs used in rail vehicles. The machine tool ensures productive machining of solid (monoblock) wheels and wheels with tires of both used and new wheelsets.
The wheelset is rolled onto the built-in wheelset elevator along rails and automatically centered and clamped between the centers and the driving dogs installed on spindle face plates and attached to the undersides of the wheel rims.
The machine tool main structure is made in the form of a portal enabling wheelsets unloading to its rear side in roll-through flow. It is also possible to unload the wheelsets to the machine front side.
