Electrode grinding wheel device with long service life

The utility model belongs to the technical field of coping wheel machining, and particularly relates to a long-life electrode coping wheel device, a plurality of groups of coping teeth are arranged on the surface of a coping wheel, the gear tooth surface angle of the coping teeth and the axis angle of the coping wheel are arranged in an angle mode, the plurality of groups of coping teeth are arranged on the surfaces of the coping teeth in an annular array mode, and the coping teeth are arranged on the surfaces of the coping teeth. According to the device, a double-grinding-wheel process is adopted, blades of the grinding wheels are removed, the grinding wheel body structure is optimized, the machining process is simple, the machining difficulty and the production cost are reduced, 45-degree grinding teeth are more stable in stress during grinding, tooth breakage is not prone to occurring, only half of a welding wheel is ground every time the two grinding wheels are ground, and through one-time back-and-forth
