Abstract
Micro deep hole drilling is one of important applications of electrical discharge machining (EDM) in the automotive, medical device and die/mold industries. Deep hole drilling is difficult due to the significant deterioration of byproduct evacuation with the drilling depth. Electrochemical machining (ECM), on the other hand, is another typical method of non-traditional machining. Because of the fluidity of the liquid electrolyte, it is difficult to realize high precision machining. Technical problems in EDM and ECM, and novel measures to realize high quality machining will be introduced and explained.
