A wheel flange plane cleaning device, in which three second cylinders drive respective first pressure blocks to extend to contact the rim of a wheel, then stepped limit rings, second cylinders and first pressure blocks position and clamp the wheel in the centers of end face support plates, the output end of a first hydraulic cylinder drives a lifting plate, a servo motor and a brush plate to extend to the positions where a brush is in firm contact with the flange plane of the wheel, the output end of the servo motor drives the brush and the brush plate to rotate at a certain speed, the servo motor stops rotating after a period of time, and the three second cylinders drive the respective first pressure blocks to contract to the positions where the wheel can be freely pulled up.

A machining jig holds a workpiece with respect to a tool that partially removes an outer peripheral surface of the workpiece. The machining jig includes a first jig including an inner peripheral surface having a shape similar to a contour of the workpiece and an outer peripheral surface including a first inclined section inclined with respect to an axial direction of the workpiece; a second jig including an inner peripheral surface including a second inclined section configured to be fitted to the first inclined section; a base to which the second jig is coaxially fixed; and a sliding mechanism that enables a large-diameter portion of the first inclined section and a small-diameter portion of the second inclined section to move toward and away from each other. The sliding mechanism of the machining jig causes the small-diameter portion of the second inclined section to press the large-diameter portion of the first inclined section so that compressive stress is applied to the outer peripheral surface of the workpiece at a position near a portion to be removed by the tool.

A fly-cutting system is disclosed, and in particular one that comprises a dynamically-controllable actuator for controlling the position, orientation, or both position and orientation of a cutting element carried by a fly-cutting head. In certain embodiments, the actuator can adjust the position or orientation of a cutting element, or both, hundreds or thousands of times per second, enabling precise control over the shape of features formed by the cutting element in a surface of a workpiece.

The method and the device are used for processing a shaft of an apparatus which supports the shaft in rotation. The device is provided with a drive unit which can be attached to the apparatus and has a drive element that can be driven in rotation by a motor and is suitable for coupling to an end of the shaft to be machined. The device also has a holding unit, which can likewise be attached to the apparatus, for at least one of the following units: a supporting bearing unit for supporting the shaft 464 to be machined; a material removal unit for removing material from the shaft to be machined at its bearing point; a material application unit for applying material to the shaft to be machined at its bearing point; and a grinding unit for grinding down the material applied to the bearing point of the shaft to be machined.

The supporting bearing unit, the material removal unit, the material application unit and the grinding unit are operable during rotation of the shaft to be machined by means of the drive unit.

Provided is a cutting tool for a sputtering target that is used to chamfer a corner portion formed between a sputtering surface and a side surface of a sputtering target, into an R plane, the cutting tool comprising: a shaft portion; and a blade portion provided at a tip end of the shaft portion, wherein as viewed from a cross section along an axis of the shaft portion, the blade portion includes: a side surface extending along the axis; a leading end surface intersecting the axis; a main concave curved surface positioned between the side surface and the leading end surface, the main concave curved surface extending from a trailing end to a leading end; a first notched surface connected between the leading end of the main concave curved surface and the leading end surface; and a second notched surface connected between the trailing end of the main concave curved surface and the side surface.

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.

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.

An automatic milling machine mills a gasket. The automatic milling machine controls the position of a cutter head relative a table. The automatic milling machine rotates the gasket with a motor. Parameters of the motor are monitored to determine the amount of rotation of the gasket.
