The invention relates to a method for the in particular material-removing machining, post-processing and/or treatment of a rail (1) by means of a milling tool, said rail being laid in a track bed. So that an inclined position of the rail vehicle carrying the milling tool, said inclined position being unavoidable in practice, and the associated inclined position of the milling tool, does not have to be compensated for using complex kinematics, the milling tool is merely displaced inwards or outwards into a second working position with a distance which is derived by the control unit from the detected measurement values of the lateral copying. In this new working position, there is, as a result of the inclined position, an unchanged machining surface (12) on the running surface (9) of the rail (1) and an advance-cutting machining surface (13) on the lateral surface (4) of the rail (1), wherein as a result of the change in distance, the material removal and the profile created as a result is set unchanged as compared to a parallel position of the milling tool.
A suction device includes a plurality of radial fans. Each respective radial fan has a suction opening for drawing in particles that are removed during processing, and an outlet opening for discharging the particles into a collection device. Each radial fan has a fan wheel driven in a rotationally movable manner about a rotation axis. The fan wheel has a circumferential face and an impact face. The impact face faces the suction opening for radially redirecting the particles that strike the impact face. The suction device further includes at least one collection channel circumferentially and partially surrounding the fan wheel of each respective radial fan. The circumferential faces of the fan wheels of adjacent radial fans delimit a roller gap. The collection channel opens in the roller gap.
