摘要：
A wire electrode supplying device in a wire cut electric discharge machining apparatus, which is capable of automatically supplying a wire electrode with accuracy during an automatic machining operation. In the wire electrode supplying device according to the present invention, an outside diameter of a pipe guide into which the wire electrode is inserted is changed stepwise, and its one end portion is made minimum in outside diameter so that the one end portion is allowed to be inserted into a machining start hole formed in a workpiece to be machined. Therefore, in machining a workpiece having a machining start hole small in diameter, the feeding of the wire electrode can be automatically, stably and accurately achieved.
