Abstract
An electrode tool for electrochemical machining includes a machining electrode surface (). The machining electrode surface () includes a conductive pattern defined by lands () and grooves () that are formed by groove machining the electrode surface (). The machining electrode surface () is then molded with a hard insulating resin layer (), and a surface of the hard insulating resin layer () is mechanically polished to expose the lands () of the conductive pattern. The lands () are chemically dissolved to obtain a conductive pattern () having a surface that is formed below a resulting insulating resin surface (), with the height difference between the two surfaces being between 1 and 5 μm. The electrode tool allows precise surface machining of work pieces and can withstand prolonged use.
