ABSTRACT:
Track wheels such as railroad wheels are trued or reprofiled by first turning or cutting over only a portion of the tread surface width of each wheel of a set, whereby the cutting depth for this initial turning is smaller than the cutting depth required for the truing. The diameters of the initially turned portions of both wheels of a set are then compared to provide a difference value. The lower diameter wheel is then turned in accordance with the respective lower diameter value. The higher diameter wheel, if any, is also turned in accordance with the lower diameter value plus in accordance with one half of said difference value.
