PURPOSE:To prevent the accuracy of machining from falling due to the eccentricity of a machining electrode, by providing detection electrodes around the guiding hole of a positioning guide made of a die guide, to detect the position of the machining electrode. CONSTITUTION:Plural electrodes 41-44 for detecting the position of a machining wire electrode 1 are provided at equiangular intervals near around a positioning guide 18 in such a manner that the line extending through the electrodes 41, 43 is coincident with a direction X and the line extending through the other electrodes 42, 44 is coincident with a direction Y. Compensation or correction is performed by motors 32, 33 so that the deviation of the wire electrode 1 in the directions X, Y are nearly zero. The wire electrode 1 is kept from curving but is made as straight as possible, when machining is performed. The accuracy of the machining is thus heightened. |
