    摘要： The invention relates to a wire guide for use in a spark-erosion device, which wire guide comprises a metal holder having an axial through-hole in which a diamond is secured. The life of the wire guide is extended by providing the holder with an electrically insulating layer. The wire guide preferably comprises an aluminium holder which is provided with an electrically insulating alumina layer by anodizing.

    摘要： A wire tension control device mounted on the wire cutting electric discharge machine and capable of accurately controlling the wire tension. The device is provided with a wire tension detecting mechanism (70) supported by a slider (72) displaceable relative to the machine proper and having a displacement roller (73) displaceable jointly with said slider. A control unit (90), which receives output signals representing an actual displaced position of a displaceable roller from a linear sensor (80) measuring in a non-contact manner the distance between the displaceable roller and a reflecting mirror on the slider by the use of laser beams, supplies, to a powder clutch (60), excited electric current corresponding to a value obtained by deducting the actual value of sensor output signal corresponding to a set value of wire tension. A clutch applies a set degree of tension to the wire (50) while exerting braking force varying according to an actual wire tension upon the braking roller (44).

    摘要： Accurate control of the tension of a wire electrode in a wirecut electrical discharge machine is achieved by eliminating a direct-current component from a speed difference signal between a braking section and a recovery section of the machine. The direct-current component of the speed signal which is eliminated is associated with the stretching of the wire electrode while under tension. As a result, the tension can be maintained constant dynamically as well as statically, thereby improving machining accuracy.

    摘要： This invention relates to a wire tension controlling apparatus which displays an alarm message when any abnormality occurs in a brake device for generating a wire tension by applying a braking force to a wire, and makes it easy to determine abnormality of the brake device. An output voltage of an inverting amplifier (4) for inverting the sign of a set wire tension voltage (Tc) from a numeric controller (CNC) is divided in a predetermined ratio by a voltage divider (R10, R11) and is compared with a detected wire tension voltage (Tf) from a tension detector by comparator (CP). When the wire tension drops remarkably due to the failure or deterioration of performance of the brake device (B), the detected wire tension voltage is lowered below the output voltage of the voltage divider and the output of an inverter (I1) disposed on the downstream of the comparator falls to a low level. Then, a light emitting diode emits light and an alarm signal is applied from a photo-transistor to the numeric controller, so that the numeric controller lets a display unit display an alarm message representing abnormality of the brake device on its screen.
