Abstract

The present invention provides a jig used for fixing a workpiece in a wire electric discharge machine. The wire electric discharge machine moves a wire electrode relative to the workpiece to process the workpiece. The jig includes: A table fixing part on the table; and a workpiece fixing part are provided with an opening through which the wire electrode is inserted, and are arranged on the opening so as to cover the opening with a fastening member from the opening direction of the opening. The upper part of the above-mentioned workpiece is fastened.

Description

technical field [0001] The present invention relates to a wire electric discharge machine, and more particularly to a workpiece fixing jig used in the wire electric discharge machine. Background technique [0002] In in-line electric discharge machining, a wire electrode is penetrated in the vertical direction of a workpiece, and electric discharge machining is performed while moving the wire electrode and the workpiece relative to each other while advancing the wire electrode. When the workpiece is mounted on the table in the machining tank of the online electric discharge machine, the workpiece is mounted on the table via a jig. [0003] Figure 8 It is a figure explaining the conventional technique which attaches the workpiece|work 8 to the table 2 via the jig|tool 6. The wire electric discharge machine includes a machining power source 1 and a table 2 . A jig 6 is fixed to the table 2 . The jig 6 is a member for fixing the workpiece 8 and is fixed to the table 2 by fi...
