本文介绍了一种新开发的制造复杂冲压模具和电解加工电极的技术，该技术具有生产率高、成本低、极其简单的特点。若干细导线通过保持器捆绑在一起，形成一束，使得导线的每一端（将是预期轮廓的表面元件）可以用超声波振动器推入，使其位于所需位置。例如，可以利用数控铣床控制每根线端的定位，定位精度在5/ 100mm的数量级。由于由多个丝端组成的模具表面不光滑，因此在毛坯和模具之间插入橡胶片，以免毛坯表面被划伤。在用丝电极电解加工时，如果丝的直径小于0.5 mm，则产品表面与用普通电极一样光滑。
This paper treats with a newly developed technique to fabricate complicated dies for press work and electrodes for electrolytic machining, which is characterized by high productivity, low cost and extreme simplicity. A number of thin wires are bound together by a retainer into a bundle so that each end of wire, which will be a surface element of an expected contour, may be pushed in with an ultrasonic vibrator to be located at a desired position. The positioning of each wire end can be controlled by utilizing a numerically controlled milling machine for instance, and the accuracy of the positioning is in the order of 5/100 mm. As the die surfaces which are constituted by a number of wire ends are not smooth, a rubber sheet is inserted between the blank and the die so that the surface of the blank may not be scratched. In electrolytic machining with a wire electrode, the surface of the product is as smooth as the one with an ordinary electrode, if the diameter of wires is less than 0.5 mm.
