FIELD: machine tool manufacture, namely machine tools for turning railroad wheel pairs without wheeling out. SUBSTANCE: machine tool includes inlet rails, outlet rails, closing rails and housing with cutter rests. Tailstocks with vertical and horizontal supporting and clamping devices are mounted in housing. There are technological flanges with high-accuracy mutual arrangement of cylindrical turning, two vertical and two horizontal basic surfaces. Turning engages with inner surface of axle; vertical and horizontal basic surfaces - with supporting and clamping devices. Such structure prevents errors of basing and provides enhanced rigidity of manufacturing system. EFFECT: enhanced efficiency and quality of machining. 2 cl, 3 dwg
