Abstract: The invention relates to a method and a device (1) for grinding a profile of a rail track intended for rail-bound vehicles using a grinding body. The support is arranged on the device (1) for translatory movement in a plane transverse to the profile by means of a guide (12) and can be applied against the profile by a contact element (13, 14) such that the support carrying the grinding body automatically aligns itself in the transverse plane in respect of the profile and in respect of the device (1). Furthermore, the support for the grinding body can be moved in a translatory oscillating manner parallel to a longitudinal axis of the profile during rotational movement, such that a profile section is worked by the grinding body multiple times and the grinding outcome is substantially improved by the translatory movement.

Abstract: 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.

Abstract: A device for milling a profile of a rail track intended for rail-bound vehicles includes at least one milling body that is capable of being driven in a rotationally movable manner about an axis of rotation, and a plurality of cutting plates attached to the at least one milling body. At least some of the cutting plates are capable of being pretensioned non-positively for fixing in a respective receiver by at least one clamping body against an abutment as a stop. The at least some of the cutting plates are capable of being deflected in the respective receiver in a radial and/or axial direction by an adjusting means and are capable of being fixed in an adjusted position by the clamping body. The adjusting means is configured to be movable and/or deformable by a pressure transmission fluid.

Abstract: 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.

Abstract: A method for stock-removal machining of a surface of a workpiece includes driving a carrier revolvingly about an axis so as to move at least one geometrically defined cutter disposed on the carrier via a receiver on a revolution path about the axis; and moving the cutter relative to the carrier during the machining, so that the cutter moves in a straight path relative to the surface of the workpiece.
