The Stanray® Underfloor Wheel Truing Machine (TN-84C) is an underfloor pit-mounted milling machine, capable of simultaneously re-profiling both wheels of a railway wheel set using the axle centers as the machining reference point. It is capable of profiling wheel sets to necessary specifications for tape size, concentricity and plane dimensions in any of the following situations: 1) while the wheel set is under a locomotive, passenger or freight car, transit vehicle, or other rolling stock, 2) while the wheel sets are mounted in a truck, and 3) while the wheel set is demounted as a single set.The Stanray will re-profile both wheels simultaneously to equal diameters, leaving a witness groove at the flange of the profile. The Full-Contour Milling Technology does not require undercutting the tread surface or flat spots by 1.6 mm (1/16 inch) as required for single point turning method on the underfloor lathe. Substantial material and cost savings, and increased mileage are therefore utilized by full contour milling. Both wheels of a wheel set will be finished automatically to the diameter that is required to clean up, while removing the minimum amount of metal possible.
