摘要： An electric discharge machining apparatus of the present invention includes a power supply, an electrode gap configured so as to be formed by an electrode and a workpiece, and an earth floating-capacitance current-suppressing coil configured to be inserted between the power supply and the electrode gap. Accordingly, the impedance in the charging path from the power supply to an interelectrode capacitance (an interelectrode parallel capacitor and an interelectrode parallel floating capacitance) can be decreased, and the impedance in the charging path to an earth floating capacitance can be increased, thereby enabling the electric current from the earth floating capacitance during discharge machining to be suppressed.

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.
