Abstract

PURPOSE:To use a wire twice for cutting materials and improve the economic effect by installing a second reel at the position of a first reel to let an old wire which is taken up pass a discharge processing part again. CONSTITUTION:A new wire 1 wound around a first reel 2 is supplied from the reel 2 to pass a discharge processing part 3, when a material is cut by discharge from this wire 1, and it becomes an old wire 5 to be taken up by a second reel 4. The second reel 4 taking the old wire 5 once used for discharge process is replaced for the first reel 2, and the old wire 5 taken around the second reel 4 is let to pass the discharge processing part 3 to cut the material again.

This is because during the first electrical discharge machining, the surface of the wire 1 becomes rough due to the electrical discharge. That is, since the old wire 5 has a larger surface area than the new wire 1, which has a smooth surface, it is thought that the discharge amount increases by the increased surface area and the cutting speed improves.

It should be noted that the cross-sectional shape of the new wire (2) may slightly deviate from the circular shape during the initial processing, and depending on the orientation of the cross-section, the dimensional accuracy may be slightly reduced upon reuse. Therefore, when using the old wire 5, it is preferable to use it for processing things that do not require much dimensional accuracy.
