There are many influence factors of electrochemical micromachining (EMM) development. So the characteristics of EMM technology were analyzed firstly. It was an effective method that the nanosecond pulses voltage was used in EMM, and the nanosecond pulses voltage was prepared to solve the problems of machining area, using small gap, and machining micro 3D structure. Its minimum pulse duration is 5ns, and its voltage, current, and duty ratio can be changed freely. Moreover, many experiments of EMM were carried into execution. After the phenomenon and results of the experiments were analyzed, the reformative project of experiment was put forward. The feasibility of the project and technique route was testified correctly by the nanosecond pulses voltage on the multifunction machine tool which was manufactured independently. After studying on the influences of EMM technology, the experiences of EMM process will be enriched and make EMM have a further development.
