    摘要: A guide device (5, 6) for the wire electrode (1) in a discharge machining apparatus is disposed just above or below a workpiece (3). The device may include three or more equally circumferentially spaced guide rings (8, 9, 10) surrounding the electrode (1) and biased outwardly by tension springs (11, 12, 13) coupled to an enclosing frame member (7) to thereby center the electrode (1) and prevent lateral displacements during use. As an alternative the rings may be replaced by guide balls biased radially inwardly against the electrode (1) by compression springs or fluid cylinders. When two guide devices are provided in the apparatus, they may be substantially identical.

    摘要: A traveling-tape electroerosive cutting method and apparatus utilizing a tape supporting guide bar (8) having two opposite, elongate surfaces (8a, 8b) extending parallel to its longitudinal axis. The bar penetrates the workpiece (1) from one side to the other side to bring the tape (2) advancing between its dispensing site (3) and takeup site (4) into firm engagement with those elongate surfaces (8a, 8b) which are shaped to enable those portions (2a, 2b) of the traveling tape (2) which are respectively in engagement with the elongate surfaces (8a, 8b) together form an active electrode surface of convexity generally V-shaped in section and juxtaposed with the workpiece (1) across a fluid-filled machining gap.

    摘要: A wire electrode discharge machining apparatus in which there is provided at least one groove (19, 20) at the end portion of a jet nozzle (17,18) through which a machining liquid (10) is jetted in order to obstruct the flow of the liquid (10) flowing into the gap space between the end portion of the nozzle (7, 8) and a workpiece (12), thereby increasing the flow of the liquid flowing along a machined slit and further improving the chip (14) exhausting performance.

    摘要: @ A traveling-wire (TW) electroerosion apparatus in which at least one of wire guides which are disposed at opposite sides of the cutting zone comprises a plurality of elementary guide members arranged one adjacent to another in the direction of wire travel and having wire-receptive notches, the notched members being staggered to make up a composite guide opening of these notches such that the diameter of an imaginary cylinder which can be inscribed therein is substantially equal to the nominal wire diameter. Preferably, the elementary guide members are arranged to be displaceable relative to one another and in their respective planes, which are parallel to one another, to change the positions of these guide notches and thus to change the diameter of the imaginary cylinder.
