Abstract
Axial tension on the wire or strip like electrode is achieved by having the electrode looped around a grooved wheel controlled by a hysteresis motor near an upper or lower guide head while the wire drive is located near the other guide head so that in the working zone the electrode is subject to the action of tensile stress necessary for electroerosion and the remaining electrode guide area is kept free from increased tensile stress on the electrode. Additionally an angle coder is used with the hysteresis motor to measure both the rotational speed and the position of the grooved wheel.
