Title: Graphite-made electrochemical machining electrode
Inventor: TAKAGI TAKASHI
IPC: B23H3/06
Filed: 1992-11-24
Abstract: PURPOSE:To shorten a machining time even when used for electrochemical finish machining a workpiece by impregnating a graphite base material with ceramic oxide. CONSTITUTION:A graphite base material 50 of constituting a graphite-made electrochemical machining electrode 10 is impregnated with oxide system ceramic, and it promotes metal elution of a workpiece 40 provided to be opposed. This elution is considered because oxygen in the ceramic oxide combines with hydrogen, generated in an electrode surface, to form water, to prevent the electrode surface from being coated with a film of hydrogen, and even when electrolyzing is advanced between the graphite-made electrochemical machining electrode 10 and the workpiece 40, an electrochemical machining speed is prevented from decreasing by fixedly holding a potential difference between the electrode 10 and the workpiece 40. As a result, no necessary cost up is caused for electrochemical finish machining.
