Abstract
The utility model relates to a combination milling cutter for machining an inner threaded bottom hole and a carbon electrode end socket. A boss, a large-end-face milling cutter frame and a cutter disc are fixedly linked, the boss is arranged at the center of the cutter disc and in line with the center line of the cutter disc. A small-end-face milling cutter frame and a cone-faced milling cutter frame are arranged on two sides of the center line of the boss and fixedly linked on the boss. The cutting blade of the large-end-face milling cutter is vertical to the axis of the cutter disc. The main cutting blade of the small-end-face milling cutter is vertical to the axis of the cutter disc. The length of the main cutting blade is equal to the radius of a small end of the bottom hole. The distance between the main cutting blade and the cutting blade of the large-end-face milling cutter in a vertical direction is identical with the depth of the bottom hole. The vice cutting blade of the small-end-face milling cutter is parallel to the axis of the cutter disc. The main cutting blade of the cone-shaped cutter is inclined relative to the axis of the cutter disc and degree of inclination is identical with a cone half angle. The vice cutting blade of the cone-faced milling cutter is vertical to the axis of the cutter disc and the length of the vice cutting blade is identical with the radius of a small end of the bottom hole. The vice cutting blade shares the same height with the main cutting blade of the small-end-face milling cutter. The combination milling cutter for machining the inner threaded bottom hole of the carbon electrode end socket can perform machining of an electrode end face and the cone-shaped bottom hole once and is accurate in precision, capable of simplifying equipment and crafts and capable of improving production efficiency.
