ELECTROCHEMICAL MACHINING METHOD FOR MANUFACTURING SUPERFINE CYLINDRICAL ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide an electrochemical machining method for producing a superfine cylindrical electrode having a constant diameter change by its length, by adjusting an amount of a current applied. SOLUTION: After a negative voltage is applied to a negative electrode rod 1 of a carbon component and a positive voltage is applied to an object to be machined 3, they are received and stored in an electrolyte 5 contained in a container having a fixed size, and a superfine cylindrical electrode having a constant diameter change by its length is produced by electrochemical machining by adjusting an amount of current applied. Ultrasonic cleaning is applied to the object to be machined by using acetone and distilled water in order to remove foreign matter sticking to its surface. The electrolyte 5 is potassium hydroxide solution having the number of moles of 4-5 Mol.
