摘要： An upper guide assembly for a wire cut electric discharge machine adapted to be mounted with an automatic wire feeding mechanism, which holds the wire without direct mechanical contact. A hold jet nozzle is connected to the upper portion of a body 23, while an upper guide is connected to the lower portion of the body. The body includes an electrode roller for supplying electric power to the wire, and an electrode pinch roller capable of coming into and out of contact with the electrode roller. The hold jet nozzle includes a through hole whose center axis is aligned with a wire path a provided in the upper guide assembly and extending vertically, and a supply passage for pressurized machining fluid communicating with the through hole. The upper guide contains a die guide and an upper nozzle. A guide axis of the die guide and a center axis of the upper nozzle are aligned with the wire path a. During operation of the wire cut electric discharge machine, pressurized machining fluid is supplied to the supply passage to form a water pillar, which produces an urging force in the upper guide assembly, whereby the wire is guided through the upper guide assembly by the water pillar without contacting with interior parts of the assembly.

摘要： A method and an apparatus for easily and reliably removing cut-out pieces cut out from a workpiece by wire-cut electric discharge machining, in which, upon completion of cutting a piece (41) out, a constraining assembly (63) mounted on the distal end of a piston (62) is brought close to the top surface of the piece under the control of a numerical control unit, and machining fluid is upwardly jetted from a lower nozzle (19) toward the bottom surface of the piece, to thereby hold the piece in the workpiece, with the piece kept away from the lower nozzle and prevented from being detached upwardly from the workpiece. While jetting the machining fluid, a worktable is horizontally moved to cause the cut-out piece to move in unison with the workpiece away from the lower nozzle in the horizontal direction. At a moved position where the machining fluid jet normally no longer acts on the bottom surface of the piece, the table movement is stopped and the machining fluid is downwardly jetted from auxiliary nozzles (70) toward the top surface of the piece, to thereby forcibly drop the piece off the workpiece.

摘要： A wire electrode guide apparatus (1) in a wire-cut electric discharge machine includes a switch valve (80) for supplying pressurized air and preventing the supply of the air to an air pressure-operated actuator (70) for driving a movable piece (40) for three point-support of a wire electrode (3) between the movable piece and a stationary piece. During wire extension, an air supply port (88) of the switch valve is communicated to a switch port (87) thereof through which the pressurized air is supplied to the actuator to move a piston rod (73) of the actuator away from the movable piece to release an urging force acting upon the same, resulting in easy insertion of the wire electrode between the stationary and movable pieces. During electric discharge machining, the switch port is disconnected from the pressurized air supply port to prevent the air supply to the actuator, so that the movable piece is urged by the actuator for wire support. A highly pressurized working fluid injected from a nozzle (51) and penetrating into the actuator through gaps between apparatus components is discharged outside the apparatus through the switch port and a pressure relief port (89) in communication therewith, so that the actuator is prevented from decreasing the urging force acting upon the movable piece to thereby accurately support the wire electrode on a predetermined traveling path.

摘要： A wire tension controlling method in a wire cut electric discharge machine, capable of preventing occurrence of an excessive variation in a wire tension which may be caused by an abnormal operation of an electromagnetic powder brake upon start and release of application of the wire tension, and upon change of same. When the presence of a possibility of an actual wire tension being excessively changed is determined on the basis of the result of comparison between a present instructed wire tension and a new wire tension, a process of adding or subtracting an upper limit variation amount, set beforehand to such a value which may not cause the excessive variation in the wire tension, to or from the present target wire tension is repeatedly effected at predetermined intervals of a cycle until the target wire tension reaches the instructed wire tension, so that the electromagnetic powder brake effects a braking operation at an operation voltage corresponding to gradually changing target wire tension, so that the actual wire tension is gradually changed to the instructed wire tension.
