Abstract :
In order to pierce hole of about several micro-meter diameter on stainless steel and so on, a punching method in which a number of techniques were developed. A ceramic fiber cut, ground, polished and gripped by punch holder, and then it could be ceramic used for a punch. Worked material was fixed on a die by vacuum pressure. particularly, a die hole was made by electric-discharging where the fiber punch was used for a cathode electrode. Consequently, the axis of the punch and the die could be positioned with each other.
