Patent JP-S63102834-A (JP)
Title: Wire-cut electric discharge machining device
Inventor: TOMIZAWA MASAO
IPC: B23H7/10
Filed: 1986-10-17
Abstract: PURPOSE:To enhance the accuracy of machining and the life of a wire electrode, by providing a device for detecting the diameter of a wire to be used, and by providing a mechanism for adjusting the shift of a positioning wire guide with respect to the axis of the wire guide in accordance with the diameter of the wire electrode. CONSTITUTION:A control circuit 7 converts a signal from a detector 6 which measures the diameter of a wire 1, into a control signal adapted to obtain a shift DELTAy2 of a wire guide 2, with which the pressing force of the pressing wire guide 3 is constant and the wire electrode 1 becomes linear with respect to a workpiece 5. A voltage produced by a control signal is effected in a variable voltage unit 8, and is applied to a multiple layer piezoelectric element 9 which supports the wire guide 2 while it is attached to a stationary wall so that a thicknesswise displacement in accordance with an applied voltage V is effected. Therefore, the shift DELTAy2 between the wire guide 2 and the axis of a positioning wire guide 4 as indicated by the one-dot chain line varies. As a result, even though the diameter of the wire electrode 1 varies, the pressing force of the pressing wire guide 3 may be maintained to be constant, and the wire electrode 1 may become linear.
