摘 要：
PURPOSE:To eliminate the need for replacing a weight in accordance with a machining purpose and improve operation efficiency by engagingly
providing a torque generating mechanism with a wire electrode and making a varying control of the tension of said electrode. CONSTITUTION:A torque generating mechanism with which torque can be freely controlled, is engagedly provided along a wire electrode in a position between idlers 14b, 14c. When the value 52 is operated to generate a torque in the same direction as that in which the wire electrode is traveling. Then, a supplementary pulley 50 adds force in the travelling direction of the electrode, varying the value of tension to one in which the force generated by the pulley 50 is subtracted from half the
weight of a weight 60. When the value of tension of the electrode is to be
increased, a torque is generated in the opposite direction, to obtain the value of tension to which the force generated by the pulley 50 is added. Thus, the tension of the electrode can be freely controlled in
