Abstract
PURPOSE:To increase roundness of a hole, by securing a flexible feed pipe of machining liquid to a perforation machining electrode in the method of electric discharge or electrolytic machining and performing perforation machining while inversively rotating the electrode at every prescribed angle. CONSTITUTION:A pipe shaped electrode 1 is fixed to a spindle 2, and a feed hole of machining liquid provided in the electrode 1 is communicated to the upper end of the spindle 2. A flexible feed pipe 9 of machining liquid is secured to the upper end of the spindle 2, and machining liquid is fed to a machined part by a pump 10 through said feed pipe 9 of machining liquid. A machining power source 11 is connected to said electrode 1 and a work 12 to perform electric discharge or electrolytic machining. The electrode 1 is inversively rotated with the spindle 2 at every prescribed angle by a motor 7 and inversive rotary mechanism 8, and torsion of the feed pipe 9 of machining liquid is limited to not more than a prescribed value.
