  • Patent number: 9849529
    Abstract: There is provided a wire electrical discharge machine that includes a temperature detection unit, an actual position correction amount calculation unit, a correction amount calculation unit, a correction amount adjustment unit, a position correction amount adjustment unit, and a corrective movement amount calculation unit. The actual position correction amount calculation unit calculates an actual position correction amount for an upper/lower guide section in accordance with reference position coordinates at a reference temperature and with actual position coordinates at a temperature different from the reference temperature. The correction amount calculation unit uses a prepared correction amount arithmetic expression. The correction amount adjustment unit calculates a correction amount adjustment value from the actual position correction amount and the position correction amount.

  • Publication number: 20170008111
    Abstract: A working fluid supply device for an electrical discharge machine is provided with a first liquid circuit configured to supply clean water (working fluid) drawn up from a clean water tank to a machining tank and a second liquid circuit configured to supply the working fluid to an ion-exchange resin and a cooler. The controller is configured to open or close a first valve provided in the first liquid circuit and a second valve provided in that part of the second liquid circuit through which the working fluid is supplied to the ion-exchange resin, thereby switching the supply of the working fluid to the first and second liquid circuits.

  • Patent number: 9364911
    Abstract: A working fluid supply device of an electric discharge machine draws up a cleaned fluid from a cleaned-fluid tank by means of a pump and supplies it to a working tank. The pump is connected with a first fluid circuit configured to supply the drawn cleaned fluid to the working tank and a second fluid circuit configured to supply the drawn cleaned fluid to an ion-exchange resin and a refrigerator. In supplying the cleaned fluid to the working tank, the first and second fluid circuits are opened and closed, respectively. In supplying the cleaned fluid to the ion-exchange resin and the refrigerator, the first and second fluid circuits are closed and opened, respectively.

    Abstract: There is provided a wire electrical discharge machine that includes a temperature detection unit, an actual position correction amount calculation unit, a correction amount calculation unit, a correction amount adjustment unit, a position correction amount adjustment unit, and a corrective movement amount calculation unit. The actual position correction amount calculation unit calculates an actual position correction amount for an upper/lower guide section in accordance with reference position coordinates at a reference temperature and with actual position coordinates at a temperature different from the reference temperature. The correction amount calculation unit uses a prepared correction amount arithmetic expression. The correction amount adjustment unit calculates a correction amount adjustment value from the actual position correction amount and the position correction amount.

  • Publication number: 20140197138
    Abstract: While machining is carried out according to a machining program by an electric discharge machine, the pressures of a machining fluid supplied from upper and lower nozzles are detected and displacement amounts of upper and lower wire guides are obtained from the detected pressures. Further, positional compensation values of the upper and lower wire guides are calculated on the basis of the obtained displacement amounts, and command values of the machining program are compensated on the basis of the calculated positional compensation values.
