摘要： An internal broaching tool for broaching profiles delimited by a root and flanks in one aspect arranges a relief part between the toothed part and the calibration part. The calibrating broaching teeth in adjacent rows on the calibration part have a guiding flank (without a clearance angle or with a maximum negative clearance angle of 0.1°) and a cutting flank (with a positive clearance angle). The guiding flanks and the cutting flanks on the calibrating broaching teeth located behind each other in the direction opposite the broaching direction are alternately offset relative to each other in adjacent rows. The position, shape, and size of each guiding flank located downstream in relation to the direction opposite the broaching direction are associated with the position, shape, and size of the associated cutting flank (or the flank of the broaching tooth) in the preceding row.

摘要： A machining system includes a support configured to retain an article, such as a rotor disk, having an area, such as a surface of a slot in the disk. A cutting tool, for example, a broach, is movable relative to the support to cut the area. A heating member, such as a laser, is configured to locally heat the area of the article. In one example, the cutting tool includes a body having a cutting edge. The heating member is supported by the body and is configured to provide heat adjacent to the cutting edge. The cutting edge cuts the locally heated area while the area is still heated.

摘要： A broach tool comprises a very stiff backing member and has an arbor adapted to be received into the hollow spindle of a machine tool, for example a multi-axis, computer controlled machining center. The backing member carries a plurality of cutting points disposed to perform successive cutting operations as the broach tool is pushed through a workpiece by relative movement of a worktable and the machine spindle. The broach tool is formed with externally extending passageways to supply coolant to the cutting points. The coolant may be supplied through the machine spindle.

摘要： A broach assembly includes an elongated base having a central upward projection and a pair of side flanges and a tapered undersurface. Releasably mounted on the projection are multiple tool holders spaced along the length of the base. The tool holders mount cutters for engaging active surfaces of the wedge slot as the broach assembly is passed through the wedge slot. Shims may be interposed between the tool holders and base to increase the elevation of the cutting surfaces relative to the undersurface of the base to progressively increase the bearing pressure of the cutting surfaces against the active surfaces of the slot during multiple passes of the broach assembly through the wedge slot.

摘要： The invention concerns a spindle (1) for machining inner grooves and comprising a cylindrical input guide (15) of diameter D1 and a cutting portion (20). Said spindle is characterised in that the cutting portion (20) is subdivided into a plurality of cutting sections (25) separated by realigning guides (26) having a diameter equal to diameter D1 of the input guide (15), so as to accurately centre the grooves relative to the hole previously machined in the workpiece (30).

摘要： A helical gear tooth broach is provided which does not require to clamp strongly the work to be broached by a special clamping device, and which does not perform an intermittent cutting action against the work. A gear tooth broach is provided having an elongate body having a series of axially aligned and spaced teeth disposed thereon. The direction of tooth spaces or traces of the teeth in a longitudinally extending helical alignment and the direction of the gullets of the teeth in a general side by side circumferentially extending helical arrangement are both oriented to the same hand of helix angle.
