The invention relates to a production method for a high-precision ultra-thin edge thick lens. The production method sequentially comprises the following steps of: 1) milling; 2) accurate grinding; 3) polishing, 4) coring; and 5) inspecting. By the production method, the thick lens is directly positioned and ground to ensure that the edge thickness is not influenced by other factors, the trimming frequency and wearing of grinding pellet sheets are reduced and the inspection qualification rate is over 98 percent by replacing a fixture or bond with the curvatures of an upper die and a lower die under the concentric rotation of a main shaft and an auxiliary shaft by the buffer process of the upper die and the lower die.
