A new micro-machining technology——ECM combined ultrasonic vibrating micromachining process is advanced. The micro-machining system is designed and built. Micro-cathodes manufacturing technology is studied. The cathodes that have different section shapes are made by electro-discharge micro-machining. A series of micro-machining tests are carried out for manufacturing micro-instruments, The feasibility and the advantages of the technology are proved. The micro-instruments with good machining precision, productivity and surface quality are manufactured. The process characteristics of the combined micro-machining are discussed.
