The paper presents a new method of electrical discharge machining for small-holes in which critical value of machining can be less than primitive EDM system generates. In this study

the characters of small-holes EDM in area equalization by current dividing were studied. The research outcomes provided a foundation for small-holes EDM in area equalization by current dividing. After that

experiments to verify the stability and feasibility of EDM in area equalization by current dividing were carried out and analyzed. The results of the experiments show that drilling speed and discharge gap decrease a little，but electrodes wear .increases slightly. There is a consistency in processability between single and double electrodes

and the method helps to control the dimension precision. In a word

it is that the method in EDM by current dividing in the condition of process stability is a novel method in small-holes.
