摘要： An electrical discharge machine feeds an electrode wire received within a guide tube to a process region of a machined article. The electrical discharge machine includes a cylindrical hollow driving shaft arranged in a vertical direction, which has a space for receiving the guide tube with the electrode wire along a vertical central axis. A head assembly includes a first holding member for holding the guide tube, and a second holding member for holding the electrode wire extending from a bottom opening of the guide tube. The head assembly is detachably coupled with a bottom portion of the driving shaft. Therefore, the electrode wire can be replaced by replacing the head assembly.

The layered anisotropically conductive element includes high conductivity layers and low conductivity layers alternately laminated on each other, the high conductivity layers and the low conductivity layers being made of thin metallic plates coated with an insulating film. The layered anisotropically conductive element has an anisotropic conductivity, in which the conductivity in a direction parallel to the low conductivity layers is much higher than that in a direction perpendicular to the low conductivity layers. The resistant element is connected to one of end surfaces of the layered anisotropically conductive element perpendicular to the layers. The feed element is connected to the resistant element.

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 in X-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.

摘要： A detected value indicating a machining state is filtered and a machining gap between an electrode and a workpiece is adjusted by using a control variable obtained through the filtering. Therefore, machining speed can be improved by maintaining a stable machining state through suppression of a disturbance in a gap distance control system due to eccentricity of an electrode, due to fluctuations in electric characteristics at feeding brush sections, and due to mechanical resonance of the electrode driving system.
