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.
