    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.

    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.

    摘要: A layered anisotropically conductive element, a resistant element, and a feed element constitute an electrode for discharge machining. 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.
