FIELD: mechanical engineering. SUBSTANCE: method comprises machining the end face of a rail. The rail is set so that to allow its end faces to be shifted with respect to the base plane, which corresponds to position of a cutting tool at the end of its working stroke providing an allowance. The value of the allowance is corrected at the second end face. The rail is set in the second machine-tool in two stages. At first the rail is moved until the second end face is at a given intermediate position in the zone of machining. An axial force is then applied to the first end face, which has been already machined, and is shifted until this end face is at a distance from the base plane that is equal to the given size of the profile. EFFECT: simplified method. 2 cl, 4 dwg
