Abstract：EDM forming machining for outer profile of circular pieces is realized by functional developing and technology researching on EDM honeycomb grinder. This technology is a new and unique machining process,it breaks through the traditional process of EDM honeycomb grinder that only grinds the inner wall of ring part honeycomb piece, it realizes low-cost and high-efficient grinding and forming machining for workpiece outer profi le, and solve many technical problems, for instance, the material is diffi cult to grind, the surplus of the special surface structure is diffi cult to decrease and so on.
