| 20090152785 | ALIGNMENT APPARATUS AND ORIGINAL POINT RETURNING METHOD OF ALIGNMENT APPARATUS, TURNING TABLE, TRANSLATIONAL TABLE, MACHINE INCLUDING ALIGNMENT APPARATUS AND MACHINE CONTROL SYSTEM - There is provided an alignment apparatus of rotating a table by translational driving to be able to operate the table in XYθ, Yθ, or θ accurately. | 06-18-2009 |
| 20090250858 | INDEXING TABLE APPARATUS - There is provided an indexing table apparatus which has enhanced table rigidity by eliminating a portion for cantilever-supporting the load of the table and which can therefore significantly reduce the deformation of the table due to the load of a large-sized workpiece, thus enabling precision machining of the workpiece. The indexing table apparatus includes: a table for placing a workpiece thereon, horizontally supported by a support shaft and having a downwardly-projecting peripheral portion which has a lower sliding surface; a table base having a supporting portion which has a supporting surface on which the sliding surface of the peripheral portion of the table slides, said support shaft being fixed vertically and centrally to the table base; a bearing, mounted to the upper end of the support shaft, for supporting the radial load and the thrust load of the table; a plurality of clamping devices circumferentially disposed at positions radially inside the supporting surface, each clamping device having a clamping shaft that engages a to-be-clamped portion formed on the inner side of the peripheral portion of the table; and a table driving device having a large ring gear secured to the table at a position radially inside the clamping devices. | 10-08-2009 |
| 20090309281 | METHOD AND FIXTURE FOR HANDLING AND PROCESSING DIE COMPONENTS - A fixture for machine tools and the like includes a base member and first and second workpiece support units that are movably connected to the base member and define a space therebetween. The fixture includes a drive assembly that is operably connected to the workpiece support units to move the first and second workpiece support units towards and away from one another. The workpiece support units each include a wedge member extending toward the space between the workpiece support units. The wedge members include opposed engagement surfaces that taper towards one another for engaging slots in opposite ends of a workpiece. Each of the workpiece support units also includes a clamp for clamping a workpiece as it engages the wedge members. | 12-17-2009 |
| 20090315237 | Button actuated detent system - A detent system that includes a plurality of detent recesses formed in a first component, a detent pin that selectively engages at least one of the detent recesses, a linkage connected to the detent pin, and a detent button that is associated with a second component. There is preferably a slot formed in at least one of the detent button and the detent pin, where each slot slidably receives an end portion of the linkage. The detent system is preferably configured and arranged such that applying a force to the detent button to move the detent button in a first direction causes the linkage to move in a second direction, which is different than the first direction, thereby resulting in disengagement between an engaging portion of the detent pin and a relevant one, or more, of the detent recesses. Such disengagement allows for relative movement between the two components. | 12-24-2009 |
| 20100078866 | METHOD AND DEVICE FOR THE COMPENSATION OF GEOMETRICAL ERRORS IN MACHINING MACHINERY - A method of measuring the forces that arise in a processing machine when processing is carried out and compensating geometrical errors caused by these forces, where a workpiece holder ( | 04-01-2010 |
| 20110291340 | METHOD AND APPARATUS FOR CLAMPING RECTANGULAR PARALLELEPIPEDIC WORK - A rectangular parallelepipedic (cuboidal) work is fixed by clamping the opposing two edges between clamp jaws attached to a pair of clamps. With the work fixed, at least one surface of the work is machined. Then, the position of the work is changed by rotating the clamps and the work all together around the rotating axis, and the other surface is machined. The foregoing step is repeated to machine all the six surfaces of the work, during which the work is kept fixed by clamping. | 12-01-2011 |
| 20150298273 | Micro-Adjustable Flip-Away Work Stop for Strut Systems - A work-stop and work-adjustment assembly for use in the metalworking and woodworking fields which is meant to run within a strut system (as in Unistrut or a comparable product) and is comprised of a four-piece assembly. The design of the assembly allows for the fine adjustment of a piece of material and can be “flipped-away” out of the work piece plane in order to clear a work table surface. The present invention is unique in that it can be used in both woodworking and metalworking applications, and can be used to make a traditionally imprecise function—such as cutting on a radial arm saw—accurate to around ten thousandths of an inch (˜0.010″), and in some cases to around 5 thousandths of an inch (˜0.005″) depending on the instrument and material to be cut. | 10-22-2015 |
