【Abstract】 Based on the advantage of no electrode loss of electrochemical machining(ECM),a micro-structure process of microfluidic chip injection mold for micro ECM was studied,then key issues such as online preparation and measurement of micro-electrodes and the precision of microstructure formation were solved for micro V-grooves and micro-holes. The processing experiments show that the process can realize the curved V-groove and group microstructure processing,and the mold processed by the micro-electrolysis has high shape precision and surface quality.更多还原
