    摘要： A machining condition is controlled by an electrode drive unit consisting of a machining electrode (101) mounting unit (106), radial drive units (107, 108) for supporting and driving the mounting unit (106) in a radial direction and in non-contact, and thrust drive units (111, 112) for supporting and driving the mounting unit (106) in a thrust direction and in non-contact, and by adjusting the position of the machining electrode (101) by means of the electrode drive unit. Such arrangement restrains an increase in mass of a portion to be driven concurrently with the electrode, and delivers a high responsiveness in X-axis, Y-axis and Z-axis directions, thereby providing an electric discharge machining device capable of being improved in machining speed and machining precision.

    摘要： A work station for an electrical discharge machining apparatus, including a first mechanism (26) for retaining a workpiece (28) in a predetermined position, at least one electrode (30) for forming a feature on the workpiece (28), and a second mechanism (32) for positioning the electrode (30) in a manner that is movable into and out of engagement with a designated portion of the workpiece (28). A portion (34) of the second mechanism (32) is connected to the first mechanism so as to automatically align the electrode (30) with the designated portion of the workpiece (28). The second mechanism (32) is configured so that the electrode (30) is electrically insulated from the workpiece (28).

    摘要： A wire electric discharge machining apparatus (100) includes an upper support (6) that supports the upper guide unit (82) that guides a wire electrode (W) on an upper side. The upper support (6) includes an arm (61) having a lower end provided with the upper guide unit (82), an axis drive portion (51) moving the arm (61) in at least one axial direction and made of a material that has a larger coefficient of linear expansion than that of ceramics, and an adjustment block (62) connecting the arm (61) and the axis drive portion (51) and made of ceramics. The adjustment block (62) is fixed at a position where a displacement of the upper guide unit (82) caused by expansion and contraction of the upper support (6) is suppressed by a bimetal effect occurring on a fastening surface of the axis drive portion (51) and the adjustment block (62).

    摘要： An electric discharge machining apparatus is provided with an electrode mounting section which mounts a tool electrode, and an electrode driving section which has a radial driving section which supports and drives the electrode mounting section in a non-contact manner in a radial direction and a thrust driving section which supports and drives the electrode mounting section in a non-contact manner in a thrust direction, and a machining state is controlled by adjusting a position of the tool electrode by the electrode driving section. Because of such a structure, a mass increase of a section which should be driven together with the electrode is restricted, and high response inX-axis, Y-axis and Z-axis directions are achieved, whereby an electric discharge machining apparatus capable of improving a machining speed and a machining accuracy is achieved.
