    Abstract: A cold rolling machine and method for producing a profile on a workpiece. The cold rolling machine having two constructed tool units. Each tool unit has at least one rolling rod extending in the longitudinal direction, a tool slide, a slide drive device, a pivoting carrier and a pivot drive. The at least one rolling rod is fastened to the tool slide and can be moved in the longitudinal direction by the slide drive device. The pivoting carrier can be pivoted about a pivot axis extending in the longitudinal direction by a pivot drive. The tool slide is arranged on the pivoting carrier. An angle of inclination can thereby be set between the two rolling rods, which angle of inclination can have, for example, a value of 0 degrees to 2.0 degrees or to 0.2 degrees. Conical profiles can thereby be produced in the workpiece.

  • Publication number: 20210245249
    Abstract: Techniques for depowdering additively fabricated parts are described in which powder is separated from parts by creating a large pressure differential between the powder and parts and a nearby location. The pressure differential may cause gas to quickly flow into and/or around the powder and parts, thereby producing a force against the powder and parts. Since the powder is generally much lighter than the parts, this force may be much more effective at moving the powder than moving the parts. As a result, the powder and parts may be separated from one another. The pressure differential may be created in various ways, such as by holding the parts and part in a chamber that is pressurized with air and/or other gas(es). Rapid depressurization of the chamber may produce the aforementioned pressure differential, leading to powder movement away from the parts.

    Abstract: A central chuck including a chuck base, a first chuck and a first drill bit. The first chuck is rotatably coupled to the chuck base and has a chuck bore terminating at a lower chuck wall and a transverse locking bore. A locking plug is threaded into the transverse locking bore. The first drill bit has an upper portion, a central portion and a distal end. The upper portion has a smaller diameter than the central portion with a shoulder spanning between the upper portion and the central portion. An oblique plane defined in the upper portion inclined in a downward and inward direction toward the shoulder. Threaded insertion of the locking plug into the chuck bore interfaces with the drill bit and directs the drill bit in an upward direction and forces the shoulder into tight abutment with the lower chuck wall.

  • Publication number: 20210245266
    Abstract: A machining station especially arranged to carry out deep drill and milling operations is disclosed. The machining station now proposed presents a specific structural arrangement, enables the incorporation, contrary to already existing stations, of an axis dedicated to deep drilling, favoring the use of deep drill tools under ideal conditions, without size restriction. Accordingly, the station is comprised of an operating base, on which there lays an operating module and an arrangement module. This new arrangement for the machining station is therefore more versatile and adaptable to the specificities programmed for each part to be machined.

    Abstract: Disclosed techniques compensate for variable forces applied to a brazing head in order to more accurately maintain application of a desired lateral force by a brazing wire, filling wire or tracking finger extending from the brazing head to a component. Orientation of the brazing head is determined relative to gravity and the angle of a movable arm of the brazing head relative to a support body of the brazing head. A lateral force value measured by a lateral force sensor is adjustable based on the determined orientation of the brazing head and the determined angle of the arm relative to the support body in order to provide a corrected or adjusted lateral force value. At least a portion of the brazing head is repositioned relative to the component if the corrected lateral force value deviates from a predetermined value.
