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 milling system for milling a track surface with at least one rotatable milling plate. A modular blade system for each milling plate allows individual blades to be removed and replaced when an individual blade becomes dull or broken. The blade system also allows the milling plates to be oriented in both Type 2 and Type 3 configurations depending upon track surroundings and the presence of encumbrance. The milling plates can be mounted to a positioning assembly for adjusting the relative distance between the milling plate and the track surface as well as the angle at which the milling plate engages the track surface. The milling system can include a depth guide so as to physically prevent the milling plate from cutting too deeply into the track surface.

A cutting tool assembly for milling a rail top, includes a first section and a second section mounted to the first section. Each section includes a plurality of insert-receiving pockets for receiving a plurality of different types of cutting inserts. The plurality of different types of cutting inserts are arranged in a plurality of helical teeth that may be separated by a helical chip flute. In one embodiment, a first type of cutting insert is formed with a radius, R, a second type of cutting insert is formed with a radius, R1, and a third type of cutting insert is formed with a radius, R2, to perform a milling operation on three different areas of the rail top.

The invention relates to a method for producing a roof rack, to an extruded profile for use in a method of this nature and to a novel roof rack for a vehicle. The novel roof rack for vehicles consists of an extruded profile (1) of aluminum, wherein the rail (13) is formed by a tubular profile part of the extruded profile (1), and the end feet (11, 12) are formed from a bend section of the tubular profile part. The roof rack has different cross-sections in the longitudinal direction, which are created by machining of at least one additional profile web on the extruded profile (1). Freely selectable lateral contours (20, 20′) for a roof rack can be achieved in this way.

A portable rail weld milling machine apparatus comprises a support structure comprising a milling tool, wherein the milling tool comprises a milling head for milling a railroad rail by moving the milling tool in a first direction longitudinal to parallel railroad rails, in a second direction lateral to the parallel railroad rails, and a third direction vertically.

A support arrangement for supporting a workpiece at a processing device during processing of the workpiece. The support arrangement comprises: a fixating means adapted to arrange an abutment surface of the support arrangement in contact with one side of the workpiece when another opposite side of the workpiece abuts one or more fences of the processing device, a locking means adapted to lock the fixating means in a contact position where abutment surface of the support arrangement abuts the one side of the workpiece when another opposite side of the workpiece abuts the one or more fences of the processing device, and a connecting means adapted to connect the support arrangement with the processing device. The support arrangement may be applied e.g. at saw devices for fixating a log to be sawn, in order to achieve a satisfactory result for a sawing process, e.g. planks with a high dimensional accuracy it is important that the workpiece is reliably fixated during the sawing process.

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 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.

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.
