The invention aims to provide a processing and manufacturing method of a grid rudder. Comprising the steps of material selection, alloy forging, forge piece performance reinspection, tool selection, grid rudder rough machining, rough machining feeding amount per pass and main shaft rotating speed selection, rough machining feeding speed selection, stress relief heat treatment, semi-finish machining feeding amount per pass and main shaft rotating speed selection, semi-finish machining feeding speed selection and stress relief heat treatment selecting the feed amount of each pass of finish machining and the rotating speed of a main shaft; selecting the feed speed of finish machining; finely grinding a plane; finely sinking and punching a positioning hole and a threaded hole; according to the method, the machining efficiency and the machining quality of the grid rudder and the product percent of pass are improved by selecting reasonable machining flow, machining process parameters, heat treatment ...
