。In the wire electrical discharge machine using the electrical discharge machining wire 21 configured as described above, as in the conventional case, the wire 21 wound around the wire supply bobbin 1 is as shown in FIG.
Damper pulley 3. Pulley 4 Brake roller 5. Wire presser 6. Support pulley 7° double guide mechanism 10, 11. Support pulley 12. Pigtail guide 13. Wire wound roller 14. In this case, the pinch rollers 15 are stretched in this order and the workpiece is subjected to electric discharge machining between the two guide mechanisms 10 and 11. For example, when a rectangular through hole 20 is formed in a plate-shaped body 19 as shown in FIG. In this case, by rotating both guide mechanisms to and 11 synchronously by the rotation control mechanism 23, the sharp end 22 of the electric discharge machining wire 21 is aligned with the through hole 20.
The plate-like body 19 is moved in a rectangular manner with respect to the electrical discharge machining wire 21 while facing the inner circumferential surface of the plate-like body 19 . As a result, a through hole 20 is formed by the wire 21 between both guide mechanisms 10.2, and the four corners are right-angled. 24 has a square cross-sectional shape. Further, FIG. 4 shows a third embodiment of the present invention, in which the electric discharge machining wire 25 has a teardrop-shaped cross section.

という優れた効果を有する。As explained above, in the present invention, since the cross-sectional shape of the wire is provided with at least one sharpened part that is less than or equal to a right angle, the workpiece can be electrically discharged by facing the sharpened part to the workpiece. By setting the angle, it is possible to smoothly perform electric discharge machining on areas that were previously difficult to machine, such as the corners inside the frame, reducing machining time and making it easier to replace the wire. It has an excellent effect in that it is not necessary.
