Abstract: An apparatus for machining a profile in an inner wall of a tubular includes a frame on which a drive system is disposed, a carriage head disposed on at least one track of the frame, wherein the drive system is configured to operate the carriage head along the at least one track, a torque tube coupled to the carriage head and extending therefrom, the torque tube having a cutting tool coupled thereto, and a plurality of stabilizer pads disposed proximate the cutting tool and along a circumference of the torque tube, wherein the plurality of stabilizer pads are configured to engage the inner wall of the tubular and centralize the cutting tool within the tubular.
Abstract: The invention provides an enhanced method and system for machining an array of components. A holding mechanism is provided for holding an array of components in a machining process. The holding mechanism comprises: a rigid base plate and at least one support for holding a raw material while machining, one end of each support being coupled to the rigid base plate. The holding mechanism is further provided with a secure plate movably coupled to the rigid base plate. The secure plate is provided with one or more holding parts such as double-sided tape or guiding pins for holding the raw material. The secure plate can be elevated to hold the raw material during a machining operation such as peripheral machining.
Abstract: 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.

Abstract: A machine tool includes a first motor, a gear, and a machine element which is movable in a direction of movement by the first motor via the gear. A second motor is provided to apply a force directly upon the machine element in the direction of movement of the machine element in the absence of an interposed gear between the second motor and the machine element. The second motor is constructed to operate in such a way that the applied force counteracts an oscillatory movement of the machine element in the direction of movement of the machine element.

Abstract: A device for use with a press of the type which includes a vertical ram for exerting a force on a first part to press the first part through a second part where the first part falls free when pressed through and separated from the second part comprising, a vertically extending shaft, an arm mounted to the shaft for generally horizontal rotational movement on the arm, a catch receptacle for a first part which is pressed free of a second part, means are provided for mounting the catch receptacle on the arm at varying distances from where the arm is mounted to the shaft whereby the catch receptacle may be positioned under the vertical ram of the press and catch a first part as it is pressed free of the second part.
Abstract: An apparatus for treating the inner surface of a vacuum chamber includes a support, means for anchoring the vacuum chamber to the support and holding the vacuum chamber, a broach having a plurality of cutting edges having cutouts, and broach drive means to which the broach arranged on the support is fitted. The broach drive means unidirectionally moves the broach relatively to the vacuum chamber in an axial direction to cut off a contaminated layer on an inner surface of the vacuum chamber. The outer diameter of each cutting edge, excluding the cutouts, is set greater than that of an immediately preceding one in a direction of a rearmost edge face from a front edge face. The apparatus may also include means for supplying an inert gas or a mixture of nitrogen and inert gases to a surface of the vacuum chamber being treated by the broach, or means for supplying a lower alcohol for dissolving contaminants contained in the contaminated layer to the surface of the vacuum chamber being treated by the broach.
Abstract: A process for forming a profiled element from a generally longitudinally extending extruded sheet-form member having a plurality of transversely spaced longitudinally extended ribs upstanding therefrom is provided. The process includes the step of removing longitudinally spaced apart portions from some of said ribs by means of a transversely acting punching means.

Abstract: A broaching device and method for enlarging an opening, hollow or cavity in a workpiece comprises a broaching tool which is mounted on, or formed on, either the shaft or the nut of a ballscrew drive unit which includes a ballscrew shaft and a ballscrew nut.
Abstract: A carrier is disclosed for supporting an optical blank in the chuck of a lathe, for machining the optical blank into a lens. The carrier has a substantially cylindrical body formed of a machinable material. The cylindrical body has an opening at a first end thereof through which an optical blank can be inserted, and a retaining portion for securing such optical blank in place. In a preferred embodiment, the retaining portion is an annular shoulder extending inwardly at a second end of the cylindrical body.
