  • DOUBLE ONE-TRACK ELECTRO-DISCHARGE WIRE CUTTING METHOD
    Publication number: 20200331083
    Abstract: The present invention relates to a double one-track electro-discharge wire cutting method, comprising a step of forward wire running and a step of reverse wire running wherein a wire running direction of the step of forward wire running is opposite to that of the step of reverse wire running; with wire running in the step of forward wire running, one processing element is completed by discharge cutting processing, and with wire running in the step of reverse wire running, another processing element is completed by discharge cutting processing. The method can improve the processing efficiency and recycle the electrode wire while ensuring the processing precision.
