EMS combines electrical discharge machining technology to replace traditional machining and can be applied to the processing of structural parts with complex structures and difficult-to-machine materials. Currently, it has been successfully used in the manufacturing verification of aerospace turbofan engine diffusers. It can also be used in various processing such as special structural parts of aircraft fuselage or aerospace fasteners. In particular, whether the processed materials have difficult-to-cut characteristics, or the overall structure has an ultra-thin curved shape, and there is no residual stress on the surface of the material after processing, this technology can be completed in one go, effectively increasing production efficiency by more than three times. This technology contributes to the introduction of domestically developed independent technologies into the international aerospace component supply chain.
