Study of Micro Punching Technology Based on Micro EDM
In the self-developed micro EDM-micro punching machine tool,micro molds are fabricated online by wire electrical discharge grinding (WEDG) technology,3D micro EDM milling and reverse micro EDM.In addition,the alignment of mold and punching can be accomplished.Special-shape punched hole and blanked part have been fabricated on T2 copper,H62 brass,304 stainless steel and 3J21 alloy successfully.
