With the development of EDM technology, mixed-powder EDM technology has emerged as well. The paper introduces the experiment in which the SEFN 450 machine tools of precision EDM forming are used for the mixed-powder EDM of 65 mn steel. Through the experiment the optimum parameters of the surface treatment are obtained including the peak current of 4A , the pulse width of 3 mu s, the pulse interval of 100μs and the silica powder concentration of 25 g/L. The orthogonal test is then used to study the concentration of silica , the pulse width and the pulse peak impact on the precision of the workpiece surface.
