<p>A combined machining apparatus (2) includes a work stand (18) for fixing a workpiece (4), a jet nozzle (6) for jetting high pressure water towards the workpiece, a wire electrode (8), and upper and lower wire guides for supporting the wire electrode perpendicularly. The jet nozzle and upper wire guide are capable of being moved between an operating position where the workpiece can be cut and a respective refuge position separated from the operating position. The workpiece fixed to a work stand is cut to a desired shape by water jet cutting, and the cut surface is then finished to desired high machining accuracy using wire electric discharge machining with the workpiece still fixed to the work stand.</p> |
