An apparatus includes a milling member capable of being driven in a rotational manner, and a plurality of blade carriers attached to the milling member. Each blade carrier has a blade for chip-removing processing of a profile. A first group of blade carriers is capable of being moved relative to the milling member. Each movable blade carrier is arranged so as to be able to be radially deflected on the milling member by an actuation member during a rotating movement of the milling member. The actuation member cyclically comes into contact with a formation of the blade carrier. In a first functional position, exclusively the blades of the first group of movable blade carriers of a track path move into engagement with the profile. In a second functional position, exclusively blades of a second group of blade carriers of the same track path move into engagement with the profile.

The present disclosure relates to a rail vehicle that includes a chassis and a rail milling assembly coupled to the chassis. The rail milling assembly includes a bracket for coupling the rail milling assembly to the chassis and a milling workhead forming a portion of the rail milling assembly. The milling workhead including a spindle and a cutter depending downwardly from the spindle. The spindle and cutter are driven by a spindle motor. The milling workhead further includes a cylinder rod disposed between the spindle motor and the spindle to thereby bias the cutter towards the rail during operation.

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.

A portable rail weld milling machine apparatus comprises a metal frame that incorporates a motor with a rotary carbide tool that is able to lock to a rail or rails for stability. The apparatus houses the required guides and motors to maneuver the tool on a plurality of axes with computer numerical control (CNC). The CNC programming is able to control the carbide tool such that the welded rail can be milled to proper profile on the entire running surface, including the top, the field side, and the gauge side of the ball of the rail.
