Abstract :
The die-hole of the ultra-fine piercing was produced by electric-discharge-machining. A fiber which was used for the punch in the ultra-fine piercing was also used for the electrode in the electric-discharge-machining. Generally, a ceramic fiber is not fitted to the discharge electrode, so new discharge method should be developed. Presented techniques are coatings of gold on the electrode so as to increase electric conductivity and short time discharge so as to machine finely.
