According to principle of electrical discharge machining ,a method of preparing copper nanoparticles is put forward. In process ,the red copper and deionized water are selected to be raw material and dielectric respectively. After machining ,the debris are separated and purified. On the basis,the purified debris is analyzed by SEM and EDS,and the result shows that diameter of copper particles is about 30 nm and uniform. Formation and source of nanoparticles is explored prudently.
