Abstract
This paper describes a micro-electrical discharge machining (EDM) method with zinc electrode. EDMing to zinc with copper electrode has splendid advantages of stable process. Very small or micro size zinc electrode can be EDMed since zinc gives high speed machining with lower electrode wear ratio under the finishing process. Preformed zinc electrode with copper electrode was used to a micro-EDM. Micro holes or grooves are obtained to a stainless steel with high efficiency.
