【Abstract】 According to the characterisitcs of a small hole EDM,based on the principle of creeping motion by using WTDS-type pie2oe1ectric elements an electrode creep-micro-feeding device in volume of 80mm×60mm×40mm is developed in this paper. This device can drive an electrode in steps of 78nm with computer control. The feeding device can be applied to electrical discharge machining(EDM) It can be adopted to machine microholes without exchanging the electrode. The study is made deeply for the EDM technology of drilling small holes by using the device developed in this paper.更多还原
