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.

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 system avoids mechanically forcing a constant location of the wheel set relative to the center of rotation.

A railway wheel boring machine for machining the bore of the hub of the railway wheel. The machine includes a base, a column, a workhead sliding on the column, a rotatory boring bar arranged on the workhead, and a non-rotatory clamping plate. Associated with the non-rotatory clamping plate is a clamping unit for clamping and centering the railway wheel. The clamping unit includes at least three jaws that move along straight paths converging at the center or center portion of the non-rotatory clamping plate. Each jaw is attached to a transmission rod having a first end attached to the jaw and a second end attached to a slewing ring that is driven to rotate by actuators. The rotating of the slewing ring drives the transmission rods to move the jaws to secure the railway wheel.
