A rolling mill system for Incremental rotary shaping of an elongated workpiece is provided that includes first and second workpiece holders. A support frame has a track with the first and second workpiece holders being movably associated with the track, the workpiece holders and an associated workpiece being movable in unison along the track. A radial chuck is mounted to the frame that includes a plurality of jaws that are movable radially inwardly and outwardly. Each jaw has a tool mounted thereto that is rotatable about an axis of rotation, with the axis of rotation of each tool being oriented at a skew angle relative to the longitudinal axis of a workpiece. A source of electric current and an electrically conductive flow path are provided for flowing electrical current through a workpiece. A controller is provided that is configured to control the operation of each of the first motor, second motor and third motor, and to control the flow of current flowing through the tools to the workpiece.

A device for machining wheel running surfaces of a wheel for a rail vehicle includes a wheel machining machine having a machining tool for performing a re-profiling process on the wheel and a rolling tool for performing a rolling process on the wheel and applying a rolling force to the wheel. A clamping unit is alternatively used as a receptacle for the machining tool or for the rolling tool. A first drive motor drives a first feed axle to translate the clamping unit along a first axis. A second drive motor drives a second feed axle to translate the clamping unit along a second axis perpendicular to the first axis. A control module adjusts the rolling force by controlling torques of the first and second drive motors.

During rolling of front sections of rolling material in a rear group of roll stands of a rolling mill, rear sections of the rolling material are rolled in the front group of roll stands. A run-out speed with which the rolling material is exiting the front group of roll stands is detected. A run-in speed with which the rolling material is entering the rear group of roll stands is detected. A rolling speed with which the rear group of roll stands is driven is controlled by a controller such that a relation of the run-in speed to the run-out speed equals a predetermined value. The predetermined value is kept constant until a time point at which a tail end of the rolling material reaches a predetermined location upstream of the front group of roll stands, and is changed according to a predetermined function after the time point.

A method for machining the wheel running surfaces of wheels for rail vehicles using a wheel machining machine is described herein. The method includes performing a rolling process on the wheels with a rolling tool that applies a rolling force to the wheels, and adjusting the rolling force by controlling the torques of drive motors of feed axles of the rolling tool.

During stabilization of a metal band (1) on a roller path (2), the band (1) is to be only minimally cooled via the stabilisation. A device for that includes multiple protective runners (3), each oriented in the conveyor direction (R), for guiding the band (1), wherein the protective runners (3) are arranged above the roller path (2) and the protective runners (3) are at a distance from one another in a width direction (B) of the band (1). Multiple rows (4) of nozzles are arranged in the conveyor direction (R) or in the width direction (B) of the band. Each row (4) of nozzles includes multiple nozzles (5). The nozzles (5) are set back in relation to an underside of the protective runners (3), such that an arched band (1) cannot come into contact with the nozzles (5). A compressed air supply (6) and a network of tubes or pipelines (7) supply the nozzles (5) with compressed air, wherein the nozzles (5) apply compressed air to the upper side of the band (1) in order to stabilize the movement of the band (1) on the roller path (2).

Methods to drive material conditioning machines are described. An example method includes determining a first torque of a first roller of a material conditioning machine through which the strip material moves, calculating a second torque of a second roller of the material conditioning machine based on a relationship between the second torque and the first torque, and maintaining the relationship between the second torque and the first torque by adjusting the second torque after a change in the first torque.

An axial motor for a traction machine and an apparatus for fabricating a stator core thereof is fabricated by rolling a thin plate having open slots such that turns of the thin plate are stacked on each other. The outer circumferential surface of the thin plate is pressed using a pressing roller while the thin plate is being rolled. The thin plate is not deformed by tension, the open slots aligned in positions are accurately maintained, and the thin plate is prevented from being loose, thereby significantly lowering a defect ratio in fabrication, lowering fabrication costs, and fabricating a high-quality product.
