Abstract
A wire cut electric discharge machining apparatus capable of machining a workpiece with a machining solution to produce a work having a desired shape. The work is magnetically attracted to be held and conveyed to a desired position by one of a pair of nozzles through which the machining solution is supplied to an interelectrode gap between the workpiece and a wire-shaped electrode. Since the attraction condition is controlled to be maintained unchanged, it is possible to move and convey the work and the like to the desired position with high accuracy and safety.
