The invention provides an ultra-large depth-diameter ratio space-time separation type electric spark electrolysis composite punching device and method, and relates to the technical field of punching machining. An electric spark machining liquid channel is formed in the electric spark machining electrode, and an electrolytic machining liquid channel is formed in the electrolytic machining electrode; the electrosparking electrode is sleeved with the electrolytic machining liquid channel, gaps are reserved in the periphery of the electrosparking electrode, and the bottom of the electrosparking electrode extends out of the outer side of the electrolytic machining liquid channel. An electrolytic machining working solution and an electric spark machining working solution circulate in the electrolytic machining solution channel and the electric spark machining solution channel correspondingly, the electrolytic machining working solution and the electric spark machining working solution are mixed at the bottom of the
