| The machining of sets of rail-vehicle wheels by means of milling cutters is currently carried out with the milling-cutter axes parallel to the axis of the wheel set. Proposed is an end-milling cutter for machining wheel rims whose axis is disposed at right angles (16) to the axis (15) of the wheel set. The cross-sectional shape (17) of the wheel is duplicated on a disc-shaped body as a negative of the required wheel shape by means of a multiplicity of overlapping milling cutters duplicating the shape of the wheel, the cutters being spirally staggered round the pitch circles and designed to produce the wheel running-surface and the outwards-facing edge of the flange up to the tip of the flange or designed to produce the outwards-facing surface of the flange from the inside wheel surface to the tip of the flange. The invention is suitable for use in the bottom and top machining of wheel sets by either downcut or conventional milling. | ||||||

| Wheels of rail vehicles are trued while the wheels are kept rotating about a wheel center of rotation that is continuously corrected to keep the center of rotation in a fixed position in response to eccentricities a wheel may have, especially in its outer circumference. For this purpose, a sensor for each wheel of two wheels forming a set senses a respective excursion of a center of rotation of each wheel being trued in a set to provide respective excursion signals which are supplied to a central processing unit that provides control signals to a power drive for wheel guide rollers which support the wheel set to be trued. The power drive applies wheel position adjusting force components, preferably directed radially relative to the respective wheel rotational axis in response to the control signals from the central processing unit whereby the excursions are compensated and the wheel rotation center is kept in a fixed position. The truing machine is an under-floor machine equipped with sensors for sensing the excursions and with a central computerized control for producing correction signals from excursion signals to control the wheel guide roller power drive. | ||||||

| 9 | Milling cutter for a wheel set milling machine | US555486 | 1995-11-08 | US5678966A | 1997-10-21 | Alfred Heimann |
| A milling cutter for truing railroad wheels has a milling drive shaft (10) with at least two, preferably three, cutter sections (3, 4, 5). One fixed cutter section (4) is rigidly connected to the shaft (10). At least one, preferably two, cutter sections (3, 5) are axially shiftable along the shaft (10) and receive their torque drive through the fixed cutter section through a releasable coupling such as a claw clutch (9, 30). One axially shiftable section (3, 5) is positioned on each side of the fixed section (4), with a gap (22) therebetween. Preferably, the shiftable sections (3, 5) are interconnected (at 21) so that an axial adjustment of one section is synchronously transmitted to the other section and vice versa. | ||||||

| A multi-cartridge cutting tool includes a body with a plurality of cartridge-receiving pockets, and a plurality of insert-receiving cartridges mounted to a respective pocket. A round cutting insert is mounted to each cartridge. The pockets are formed at predetermined distances from a central, longitudinal axis of the body to form a first group and a second group of cutting inserts such that the cutting edges of the first group of cutting inserts and the cutting edges of the second group of cutting inserts are located at different axial and radial distances from the central, longitudinal axis of the body to perform different machining operations. A third group of cutting insert(s) may exist for cutting tools with an odd number of cutting inserts. The different types of machining pockets allow for high feed rates, while greatly improving the life of the cutting insert as compared to conventional cutting tools. | ||||||
| 17 | Method and apparatus for reprofiling wheels | US607246 | 1984-05-04 | US4597143A | 1986-07-01 | Theodor Dombrowski |
| The present invention relates to a method and apparatus for reprofiling the wheels of a railroad wheelset by circumferentially milling the wheelset while the wheels are driven and partly supported by drive rollers, the wheelset being partly supported at its bearing housing. Before profile milling, a reference surface is created by a turning operation as base for measuring the radial infeed of the profile milling cutter. The turning tool required is disposed on the profile milling cutter which is lockable secure against rotation. By coordinating the position of the milling devices with the position of the respective turning devices a positional relation is automatically established between the milling device and the axis of the wheelset. | ||||||
| 18 | Heavy duty insert | US946031 | 1978-09-26 | US4214846A | 1980-07-29 | Rolf H. Kraemer |
| A heavy duty insert for severe machining operations having a generally rectangular body with upstanding walls and rounded corners having a cutting edge extending around the periphery thereof and an upstanding mesa inboard of the cutting edge. To provide improved machining life the cutting edge in cross-section has an arcuate surface with a small radius merging from the walls of the body into an inclined face which is intersected inwardly of the walls by a flat land extending transversely to the walls. The maximum cutting speed and in-feed rate for machining is significantly increased by a groove interposed between the mesa and a cutting edge adjacent each side wall and having a first portion extending inwardly of and downwardly below the land of the cutting edge and a second portion defining in cooperation with a side wall of the mesa a surface extending inwardly of and upwardly above the land of the cutting edge. | ||||||
