Patent ID: 7119300

Claim:
An apparatus of asynchronous electric discharge machine for wire cut for machining a work piece, comprising: a cutting wire; a first electric discharge machine unit including an upper machine guide connecting to one end of the cutting wire to generate an ignition discharge to perform cutting machine for the work piece; a second electric discharge machine unit including a lower machine guide connecting to another end of the cutting wire to generate another ignition discharge to perform cutting machine for the work piece; and an ignition power supply device connecting to the first electric discharge machine unit and the second electric discharge machine unit to provide energy required for generating ignition operation; wherein the first electric discharge machine unit and the second electric discharge machine unit alternately perform machine for the work piece to prevent the ignition discharge from occurring on a same spot of the work piece and resulting in rupturing of the cutting wire; wherein at least one of the first electric discharge machine unit and the second electric discharge machine unit further includes a first ignition module which has one end connecting to the ignition power supply device and another end connecting to the upper machine guide to generate an ignition.
