摘要： Apparatus for and a method of electro erosion machining with increased stock removal rate with a fine finish is disclosed. The electro erosion machining apparatus disclosed includes an electrode having a plurality of separate portions insulated from each other and separately connected to a single source of pulsed electrical energy whereby the current from the source of pulsed electrical energy is divided among the separate electrode portions to provide a small current for each electrode. The method of the invention includes varying the current passed through each portion of the electrode, limiting the current through each portion of the electrode to a single direction and moving the electrode transversely of the direction of movement of the electrode toward a workpiece during electrical erosion machining to provide rapid total form machining.

摘要： A machine tool comprising a large elongated fluid tank, dry chamber boxes at each end of the tank supporting spindles having electrodes secured thereto for reciprocal movement toward and away from a workpiece positioned between the dry chambers in the middle of the fluid tank. Means for moving the dry chamber and the spindle and electrode carried thereby toward and away from the workpiece and for simultaneously rotating the spindles and electrodes. An electrical machining power supply with each spindle at each end of the dielectric tank, servo means for controlling the movement of the spindles and separate fluid supply means for passing fluid through the spindles to the electrodes. Adjusting bolt and abutment structure at one end of the tank to align the spindles at the opposite ends of the tank. Structures for hydraulically clamping a workpiece between the electrodes and for leveling a work table in position beneath the electrodes in the tank. The method including moving a pair of electrodes toward a workpiece from the opposite sides thereof, maintaining a predetermined gap between the electrodes and workpiece while simultaneously rotating the electrodes and passing an electric signal between the electrodes and workpiece in the presence of a dielectric or an electrolyte.

摘要： A machine tool for electrical machining is disclosed which includes parallel linkage structure for moving an electrode toward and away from a workpiece. The parallel linkage structure, as disclosed, is driven by servo means to maintain a predetermined spark gap between an electrode secured to the machine tool structure and a workpiece supported thereby. A fixed work table is provided as part of the machine tool structure in conjunction with a work tank having no bottom which tank is vertically movable. The fixed work table forms the bottom of the work tank with the tank in an upper position. On lowering of the tank fluid in the tank is rapidly drained into a lower storage tank from which it may be pumped through a filter after which it is stored in an upper storage for reuse. The work tank is provided with a removable upper portion to facilitate positioning of a workpiece in the fixed worktable. A universal manifold is also provided whereby different fluid flow patterns may be provided from a single manifold to facilitate machining of workpieces requiring different flow patterns. The flow patterns of the universal manifold are readily selected by rotation of cylinders in the manifold.
