  • Patent number: 8740521
    Abstract: The present invention relates to a chamfer device for machining a weld bead surface, which specifically carries out a chamfering process on the welding bead surfaces of objects to be processed (such as metal sheet materials and pipes). In the present invention, immediately after a chamfering-amount-adjustment unit has been rotated and released, a position-setting pin is inserted into a securing recess in the chamfering-amount-adjustment unit, while the chamfering amount is adjusted in precise units and simultaneously locked at a predetermined chamfering amount which is automatically maintained, and the adjustment of the chamfering amount is achieved in a straightforward fashion with just one touch. When the chamfering-amount-adjustment unit is operated, a mobile cutter shaft moves vertically and as it does so the chamfering amount is adjusted in such a way that the chamfering amount can be immediately and rapidly adjusted while continuously operating without regard to any cutter rotation action.

  • Patent number: 7914243
    Abstract: A method for removing a weld crown from a weld joint between first and second work pieces includes steps of positioning a rotary milling tool proximate to the joint and at an offset angle to set a cutting arc relative to the joint. The milling tool is positioned so the cutting arc intersects the weld crown, weld toes, and parent metal on each side of the weld joint. As the milling tool traverses the joint to cut away the weld crown, the milling tool may tilt from side to side to compensate for misalignment between the work pieces along the weld joint. An apparatus for weld crown removal holds a milling tool at an offset angle, and provides a tracking mechanism to permit the milling tool to track misalignment between the work pieces, maintaining the cutting arc in intersection with the weld toes and parent metal along the weld joint.

  • Patent number: 6626617
    Abstract: In order to further develop a process for making a groove in a board-like workpiece by means of a processing machine, wherein the workpiece is placed on a supporting table of the processing machine aligned essentially horizontal for holding the workpiece in a machining plane and wherein a milling unit held on a machining head of the processing machine is displaced and a groove is thereby milled into a workpiece by means of a milling disk rotating about a drive shaft aligned parallel to the machining plane, in such a manner that the groove can be milled more precisely with a defined groove depth it is suggested in accordance with the invention that the milling unit be guided at right angles to the machining plane by means of a touch roller associated with the milling disk and adapted to roll on the workpiece. In addition, a processing machine for carrying out the process is suggested as well as the use of the processing machine for the milling of a groove into a multilayered or composite material board.

  • Publication number: 20030165367
    Abstract: A hand-held milling machine (1) has a cutting tool (9, 10) which protrudes from a machine support (3) on the side facing the workpiece. A screw-type clamping mechanism allows the cutting tool (9, 10) and the machine support (3) to be positionally adjusted relative to each other by the relative rotational movement of clamping sections (6, 18) on both sides around a drive axis (13) in the direction of the projection of the cutting tool (9, 10) relative to the machine support (3). The clamping sections (6, 18) are positioned opposite each other in the radial direction of the drive axis (13). A tensioning device (35) allows the two clamping sections (6, 18) on both sides to be secured against relative rotational movement around the drive axis (13).

  • Publication number: 20030141621
    Abstract: A method and apparatus for forming patterns in a flat, plastic material, such as, for example sheet vinyl, linoleum, and other flat sheet floor covering. The apparatus comprises a router die and trimmer base affixed to a router machine. The router die is comprised of two guiding members, a first guiding member that directs the router blade between an edge of a pattern and an edge of an overlay. A second guiding member follows the blade after the groove is cut.

  • Patent number: 6478516
    Abstract: A machine is provided for stripping the ground wall insulation from a stator bar quickly and in such a manner that the copper strands will not be damaged. The apparatus of the invention includes a power driven cutting tool for milling or routing the insulation from a portion of the insulated bar, a sensing device for detecting the location of the copper strands and a height adjustment assembly for determining a disposition of the bar with respect to the cutting tool. In an exemplary embodiment, the height adjustment assembly is adjusted in accordance with the location of the copper strands as detected by the sensing device to substantially prevent the cutting tool from making damaging contact with the copper strands.
