ABSTRACT:
Machine provided with two grinding slippers 8 for each rail track 1 connected by a lifting jack 9, and driving beams 10, to its rolling frame 2. On each slipper 8 are mounted four grinding units 6 angularly displaced at an angle D.sub.1 with respect to each other. The slippers 8 are located in front of one another in the transverse direction of the track and are hinged on a connecting element 12 in order to be inclined at an angle D.sub.2 by means of a double-acting jack 14. The inclination D.sub.2 of each slipper is monitored by a potentiometer 27 connected to an indicating dial 28. This machine enables truing of the rail by grinding the whole profile of the rolling surface of the rails by varying the inclination of the grinding slippers at each pass.
