摘要： An electric discharge unit of an electric discharge machine is disposed in a working tank, and a working fluid in the working tank is delivered to a filter tank by a pump. A filter for working fluid filtration wound off from a roll faces apertures in the bottom of the filter tank. When the internal pressure of the filter tank exceeds a predetermined value, the filter is moved a predetermined distance downward of the filter tank. In a position off the filter tank, that part of the filter which has been used for filtration is cleaned.

摘要： A used wire cutting device for wire cut electric discharge machine which appropriately determines the time to replace a movable blade and a fixed blade of a cutting mechanism on the basis of not only time but also the degree of wear of each blade. The device includes a wear rate storage means for storing the wear rate per cut (1/P) of a blade of the wire cutting device depending on the diameter and material of the wire. The number of cuts performed during machining is obtained from the length of time from the start to the end of machining, and the number of actions of cutting per unit time. The number of cuts obtained is multiplied by the wear rate (1/P) for the wire used, and the resultant value is added to the last value of total wear rate R. With the value thus obtained, the last value of the total wear rate R is replaced. When the current value of the total wear rate R exceeds a predetermined wear rate, a message recommending blade (chip) replacement is sent out, and when the chip is replaced, the total wear rate R is reset to 0. Also when an alarm indicating wire cut failure is sent out, the chip is replaced and the total wear rate R is reset to 0. Further, the device is so arranged to be able to replace the wear rate (1/P) stored on the basis of data obtained by actual cutting.

摘要： When a wire electrode is arranged along a traveling path by manual operation, a motor M1 for feeding the wire electrode to a workpiece is driven in response to a predetermined torque command from a control section with a switch SW1 on a side a. The wire electrode is connected, and a motor M2 for delivering the electrode from the wire is driven at a predetermined speed, whereby the electrode is run. Then, the switch SW1 is shifted to a side b and a switch SW2 to the side a, and the motor M1 is subjected to torque control such that a tension on the wire electrode detected by a tension detector is equal to a command tension. When a variation of the tension on the wire electrode is converged, the switches SW1 and SW2 are shifted to the side b, speed control of the motor M1 is performed so that detected tension is equal to the command tension, and electric discharge machining is started.

摘要： A wire electrode supply device for a wire-cut electric discharge machine that prevents a wire electrode from departing from a wire traveling path using a simple configuration. A wire bobbin is driven in a reverse direction of a wire feed direction by a torque motor to apply tension to the wire electrode. A velocity detector that detects a rotation velocity of the wire bobbin is provided. The wire electrode is laid along the wire traveling path that includes a guide roller, a brake roller, upper and lower guides, and a wire take-up roller, during which, when the wire electrode is fed out from the wire bobbin, if a velocity detected by the velocity detector meets or exceeds a predetermined velocity, the output torque of the torque motor 3 is increased so that inertial force of the wire bobbin causes the wire electrode to slacken, thus preventing the wire electrode from departing from the wire traveling path. Accordingly, the wire electrode can be simply prevented from departing from the wire traveling path merely by providing a velocity detector, and since the wire electrode does not come out of the wire traveling path the work of laying the wire is made easy.
摘要翻译：一种用于线切割放电机的线电极供给装置，其使用简单的结构防止线电极从电线行进路径脱离。线轴由转矩马达沿着送丝方向的相反方向驱动，以向线电极施加张力。提供了检测线筒的旋转速度的速度检测器。线电极沿着包括引导辊，制动辊，上下引导件和线拾取辊的线移动路径放置，在此期间，当线电极从线绕管送出时，如果由速度检测器检测到的速度达到或超过预定速度时，转矩电动机3的输出转矩增加，使得线轴的惯性力使线电极松弛，从而防止线电极离开线路行进路径。因此，仅通过设置速度检测器，可以简单地防止线电极脱离线路行进路径，并且由于线电极不会从电线行进路径脱出，因此容易铺设电线的工作。
