Abstract: Apparatus for truing the wheels of a railway vehicle wheel-and axle assembly. The vehicle axle is maintained in a fixed alignment by means of retractable centers, and the truing tool rotates about an axis which is maintained parallel to the vehicle axle. Drive rollers are provided to support and drive the vehicle wheels. The drive rollers are carried by a platform mounted for limited universal movement on a hydraulic lift mechanism which supports the weight on the vehicle wheels. Resilient means are provided to damp the universal motion of the platform. The truing tool is a milling cutter having a body contoured to the shape of the vehicle wheel, with cylindrical cutting buttons affixed to the body in diagonal ranks to form a helical pattern. The buttons in the wheel flange cutting portion of the cutter body are disposed with their longitudinal axes substantially normal to a radius of the cutter body, while the buttons in the tread cutting portion are disposed with their longitudinal axes substantially coincident with a radius of the cutter body. The flange cutting buttons may be arranged in ranks which are offset from the ranks containing the tread cutting buttons, and next adjacent buttons in the helical pattern may be spaced by staggering the ranks.
