摘要： It is a purpose of the present invention to provide a wire electrical discharge machining system allowing a wire electrical discharge machining device and a robot to operate in conjunction with each other with high efficiency. A wire electrical discharge machining system 1 includes wire electrical discharge machining devices 7, 11, and 15, and a robot unit 17 that mounts a workpiece on the wire electrical discharge machining device. The wire electrical discharge machining devices 7, 11, and 15 may each perform either rough machining with supported cores or finishing machining after the cores are removed. Subsequently, core processing may be performed by means of a corresponding dedicated apparatus. Also, the core processing may be performed by means of a single common apparatus. The robot unit 17 mounts and collects the workpiece so as to allow these wire electrical discharge machining apparatuses to effectively operate, thereby providing wire electrical discharge machining with improved efficiency for the overall system.

摘要： An electrical discharge machining device is provided, using a floating capacitance to provide a machining target with improved surface roughness. An electrical discharge machining device 1 includes a current supply circuit 3 that supplies a current to a gap between an electrode 17 and a machining target 19 so as to provide electrical discharge machining. A floating capacitance portion 21 occurs between the electrode 17 and the machining target 19 in the electrical discharge machining. The floating capacitance portion 21 supplies its stored charge to the gap in the electrical discharge machining. A capacitor 11 stores a charge before the floating capacitance portion 21 is discharged. After the floating capacitance portion is discharged, the capacitor 11 charges the floating capacitance portion 21. The floating capacitance portion 21 is discharged again after it is charged. Such an operation generates a pulse current, thereby providing electrical discharge machining.

摘要： The present invention provides a wire electrode supply apparatus for suppressing wire electrode driving vibration for wire electrodes having a wide range of diameters and formed of various materials, thereby improving processed surface roughness. The wire electrode supply apparatus includes a back tension adjustment unit that adjusts a back tension of the wire electrode drawn from a source bobbin, a tension applying unit, and a constant pressure ejecting unit that ejects the wire electrode with constant pressure and rate after the transference via the tension applying unit and an electrical discharge machining unit. The tension applying unit includes a low tension applying unit that applies a tension to the wire electrode, and a high tension applying unit that can supply a higher tension. After the high tension applying unit supplies a tension, the low tension applying unit supplies a tension. Otherwise, only the low tension applying unit supplies a tension.

摘要： In a method of welding a cut-out part with a workpiece at a preselected area in a thickness direction of the workpiece in a wire electrical discharge machining to retain temporarily or tentatively the part on the workpiece, a wire electrode 5 tilted in posture cuts the workpiece 6 to form a slant cutting surface 30 at a spark discharge location in a desired contour 21 in the workpiece 6. The wire electrode 5 after kept in an upright posture executes the welding process on the workpiece 6 along the slant cutting surface. A plurality of the welded spots is formed over a preselected length at preselected areas in the thickness direction of the workpiece 6. Even if the cut-out part 26 weighs more or the spark discharge is executed on the workpiece 6 overlapped one on the other, the welding spot 20 is formed in the thickness direction of the workpiece 6 adequately depending on the working situation to tentatively retain the cut-out part 26 on the workpiece 6.

摘要： A wire electrode feeding apparatus or the like is provided, suitable for feeding a wire electrode along its original path without deviating from its original path. A conversion unit 9 feeds the wire electrode from a feeding inlet 21 to a feeding outlet 25 using a machining liquid. A roller 23 changes the feeding direction of the wire electrode. A discharging unit 27 discharges the machining liquid toward the feeding outlet 25 in a direction tangential to the contact face of the roller 23, to generate a flow of the machining liquid. On the other hand, a diverted flow path for the machining liquid is defined along the contact face of the roller 23 from the feeding outlet 25 side to the feeding inlet 21 side. An intake unit 29 takes in air according to the pressure of the machining liquid to supply the air to the diverted flow path.
