A manufacturing method of a vehicle wheel includes forming, on a front surface of the vehicle wheel, a cutting surface having a contour shape following a target contour shape that defines the shift of a target position in the axial direction relative to a position in the radial direction. The target contour shape includes an arcuate first fillet portion, a linear first flat portion, and a recess-projection portion having a recess-projection shape in which recessed portions and projection portions are provided alternately. The width of the first flat portion in the radial direction is equal to or more than twice the amount of feed per rotation in the lathe turning but equal to or less than a first predetermined distance.

A system for reprofiling a wheel set of a railway vehicle allows the center of rotation of the wheel set to move relative to supporting rollers. A cutting tool used to reprofile the wheel profile on a wheel set is moved relative to the center of rotation of the wheel set to maintain a constant distance between the center of rotation and the cutter. The rollers are maintained in a fixed position during the cutting process. The system avoids mechanically forcing a constant location of the wheel set relative to the center of rotation.

A machine tool head for machining internal surfaces of a cavity defined by a monobloc caliper for a disc brake assembly. The tool head is an angle head comprising a cutter for machining said internal surfaces and a drive train configured to connect the cutter to an actuator. The cutter comprises a first cutting edge configured for cutting as the tool head is moved in a first direction and a second cutting edge configured for cutting as the tool head is moved in a second direction.

An apparatus reconfigures or configures a wheel associated with a train. The apparatus comprises a tool configured to engage the wheel a compound slide system for positioning the cutting tool in at least two axes. The compound slide system is controlled so that the wheel is configured in accordance with a profile. The slide system can be moved mechanically and/or pneumatically and/or can use a mechanical profile. The apparatus can have a low profile and a low weight.

The present disclosure relates to a rail vehicle that includes a chassis and a rail milling assembly coupled to the chassis. The rail milling assembly includes a bracket for coupling the rail milling assembly to the chassis and a milling workhead forming a portion of the rail milling assembly. The milling workhead including a spindle and a cutter depending downwardly from the spindle. The spindle and cutter are driven by a spindle motor. The milling workhead further includes a cylinder rod disposed between the spindle motor and the spindle to thereby bias the cutter towards the rail during operation.
