A rail vehicle includes a milling device for finishing the running surface of track rails during the travel of the rail vehicle along the track rails. The rail vehicle has a chassis frame having wheel sets. The milling device is provided with a milling head, and includes a framework arranged on the chassis frame having a milling head receptacle, which is displaceable vertically and transversely in relation thereto. The milling head receptacle can be supported for the vertical guiding via a guide shoe on the running surface and for transverse guiding in parallel to the milling head shaft via a guide stop laterally on the railhead. The milling head receptacle forms a transverse carriage, which supports the guide shoe and the guide stop, and the guide path of which, which is vertically displaceable, is provided on the side of the milling head receptacle facing toward the guide shoe.

A method for machining long edges of metal workpieces (2), wherein during the machining of the workpiece (2), all the cutting edges (z) are put into engagement with the machining surface (B) over an effective length (l) and having a cutting depth (t), and the removal of the chips is effected in each case over a length which is equivalent to the tooth spacing (a.sub.s) between the adjacent teeth simultaneously with their motion along the effective length (l).

A method and related system and apparatus for refurbishing worn rail transit rails to a desired refurbished rail surface profile substantially similar to the surface profile of a newly-manufactured rail, comprising: depositing a first line of fill material along a lower-inside section to be refurbished; in N1 successive iterations thereafter, progressing circumferentially from the lower-inside section to be refurbished to an upper-outside section to be refurbished, depositing an n+1.sup.th line of fill material adjacent an n.sup.th line of fill material wherein the n.sup.th line of fill material substantially provides a flow barrier against the n+1.sup.th line of fill material flowing past the n.sup.th line of fill material.

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.

A rail processing device (1) comprising at least a first (3A) and a second work station (3B) provided on a common frame (30), and configured to alternately lock a rail (2) when the latter is being processed, each work station (3A, 3B) comprising at least a first magnetic anchorage plane (4) configured to cooperate with a web (2A) of the rail (2) when the latter is being processed in the respective station, and a transport system (50A, 50B) to move the rail (2) from the first work station (3A) to the second work station (3B) and vice versa.

A movable fixture for milling rail heads of slide rails arranged in a track bed includes: a rotating milling head mounted in a milling head drive mechanism supported by a chassis. The milling head has at least one cutting tooth comprising several cutting plates for milling the rail heads and a disc-shaped tool carrier connected to the milling head drive mechanism. The tool carrier includes cassettes assembled with cutting plates arranged around their periphery. The cassettes are arranged in several carrier segments connected to the tool carrier so they can be detached. The cassettes are arranged peripherally on the tool carrier with at least two assembled cutting plates, the cassettes being different with regard to at least one of: a number of cutting teeth; distances of the cutting teeth from each other; rake angle of the individual cutting plates; or inclination angle of the individual cutting plates.

A method of milling a profile of a railway rail comprises: rotating a milling cutter including a plurality of face mounted cutting inserts mounted about a periphery thereof; milling a railway rail with cutting edges of the cutting inserts rotating in a predetermined plane corresponding to at least a portion of a desired rail profile while controlling the depth of cut of the cutting inserts; traversing the railway rail with the milling cutter while milling the railway rail; and controlling the speed of traverse of the milling cutter along the railway rail.
