テング・ワイヤ式放電加工機。[Claims for Utility Model Registration] (1) A means for running an electrically conductive cutting wire, a means for causing electrical discharge between an electrically conductive workpiece and the cutting wire, and the cutting wire. and a means for moving the cutting wire in a direction perpendicular to the traveling direction thereof, and moves the cutting wire along the cross section of the workpiece to be cut while causing a cut in the workpiece by the electric discharge. In a cutting device for a conductive object using electric discharge, which cuts the object to be cut by cutting the object, a discharge length detects the length of a discharge region generated between the cutting wire and the object to be cut. A cutting wire type electrical discharge machine, characterized in that a detecting means and a means for controlling the running speed of the cutting wire according to the length of the discharge area detected by the discharge length detecting means are added. . (2) The discharge length detection means includes a contact that slides into contact with the outer peripheral surface of the object to be cut, a variable electrical resistor that interlocks with the contact, and the variable electrical resistance based on the displacement of the contact. The cutting wire according to claim 1, characterized in that the cutting wire comprises means for detecting a resistance value of the device, and is configured such that the length of the discharge region is detected based on the resistance value. EDM machine.
