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.

Provided is a machine tool configured for machining by removing material from an object defining a machining surface and including a removal tool of material from the object and driving means configured to be placed directly in contact with the machining surface and to move said machine tool and, thus, the removal tool, with respect to the object.

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 machine tool includes a frame with two opposite frame sections, a number of leg elements arranged on the frame, and a first carriage having a first linear axis. The first carriage is guided on the two opposite sections of the frame and is displaceable in a first direction. A second carriage of a second linear axis is guided on the first carriage and is displaceable in a second direction A tower element has a third linear axis, which is retained on the second carriage. A machining element is retained on the tower element and is displaceable in a third direction, and a tool spindle is arranged on the machining element for receiving a tool.

A method and apparatus for the refurbishment and repowering of wind turbines through the extension of existing installed blades so that they can catch more wind energy and therefore enable an increase in the overall average power output of the wind turbine.

A redressing device (100) for redressing a tapered portion (12) of an orthopaedic implant (10) comprising: a grinding member (110) adapted to engage the tapered portion (12); an adjustable guide element (130) for defining, at least in part, the degree of redressing required for said tapered portion (12) by a user; and a drive shaft (120) for driving movement of said grinding member (110). A device for retaining debris produced during redressing a tapered portion (12) of an orthopaedic implant (12), a surgical kit for redressing a tapered portion (12) of an orthopaedic implant (10) and a method of redressing a tapered portion (12) of an orthopaedic implant (10) are also provided.

Provided is a tool system for including a machine tool configured for machining by the removal of material an object defining a machining surface.

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.
