  • Patent number: 6183175
    Abstract: A tool holder for a tool drive with an outer and an inner concentric drive shaft. A first adapter is detachably held by a conventional clamping system in a receptacle of the outside drive shaft. A second adapter is concentrically mounted in the first tool receptacle of the first adapter so as to rotate with respect to the first adapter. The second adapter has a tool receptacle which can be inclined by a pivoting element. Thus, a tool can be eccentrically inserted and concentrically driven. This makes possible certain machining modes, for example the machining of a hollow shaft, since inner threads can now be turned rather than cut.

  • Patent number: 6178615
    Abstract: A long length product is conveyed along a conveyor by a propulsion mechanism into contact therewith. The product is gripped by a first conveyor line vise and cut at its tailing end side to a specified dimension. The product is advanced by the propulsion mechanism against the conveying force of the conveyor and then gripped by the first conveyor line vise and machined. A series of these operations are iterated. Finally, the product is advanced to a second conveyor line, where it is gripped by a second conveyor line vise and subjected to final machining with the propulsion mechanism retracted. Instead of using a process of cutting to cut the leading end side of the product to a specified dimension, the leading end side of the product may be put into contact with the stopper and fed by referencing the leading end of the product.

  • Patent number: 6178616
    Abstract: A circulating type milling apparatus for milling a lock core keyway includes a frame with a rotating disc that is intermittently rotated through a pre-determined angle. Lock core seats are equidistantly provided on the rotating disc. A milling disc is mounted to a top plate of the frame and includes cutters, ejecting plate, and detectors mounted thereon. The cutters are lowered to mill a keyway in each lock core. When the cutters are further moved downward and thus disengaged from the lock cores, the rotating disc is rotated by a distance that is equal to a half distance between two adjacent lock core seats such that each lock core seat is in a positioning in alignment with an associated detector yet not in alignment with an associated cutter. When the milling disc is moved upward, the detector checks whether the milled keyway of the lock core meets the required standard. The ejecting plate ejects the finished milled lock core, and a new lock core is fed by a lock core supplying device.

  • Patent number: 6178610
    Abstract: A method of and device for removing burrs from metal work-pieces processed by a metal processing machine is provided. The method and device both include the burrs being removed by a high pressure stream of liquid that exits a high pressure nozzle and is directed at the work-piece that is to have the burrs removed. An integration of the burr removal step into the manufacturing sequence of the parts on commercial metal processing machines is made possible by the fact that the high pressure stream of liquid that is used has a proportion of oil of greater than 50% and a high pressure of greater than 400 bar.

  • Patent number: 6176656
    Abstract: A machine tool comprises a spindle stock and a worktable provided in front of the spindle stock to support workpieces thereon and capable of up-down movement and swivelling movement about a vertically extending center axis. Also employed in the machine tool is a splash guard arrangement which spatially divides the worktable into a machining region disposed in proximity to the spindle stock and a mounting region positioned distal to the spindle stock. The splash guard arrangement includes a rotary guard rigidly attached to the worktable for movement as a unit with the worktable, a stationary guard provided above the rotary guard and a sealing slider elevationally movably held by the stationary guard. The sealing slider remains in pivotal engagement with the rotary guard so that the slider can be subjected to up-down movement together with the rotary guard, while allowing the swivelling movement of the worktable and the rotary guard independently of the slider.

  • Patent number: 6174271
    Abstract: A high throughput drilling system for printed circuit board hole formation. Two spindles are disposed at each spindle station, doubling the number of holes produced in a given time period. Each spindle in connected to an overhead linear drive by a mini slide. A first set of the spindles, one for each spindle station, is driven by a first X axis linear drive. A second set is driven by a second X axis linear drive. The work piece table is elongated to support work pieces for all stations, and is supported by a set of bearing guides, with outrigger bearings coupled to the table by flexure mounts that relieve stress due to differential temperature expansion rates between the work piece table and the base table. High speed spindles are employed to obtain higher productivity, with larger holes routed by router tools, eliminating the need for stocking large drill sizes on the system tool changer.
