The utility model relates to a whirlwind envelope NC screw milling machine, belonging to the NC machine tool field, which comprises a lathe bed and a tool carriage; wherein a whirlwind mill head component is fixed on a small tool carriage, the small tool carriage can be horizontally slidably arranged on the a large tool carriage, and the large tool carriage can be horizontally slidably arranged on the lathe bed. The whirlwind mill head component comprises a mill head bracket, a mill head drive motor, a facer and a rotary sleeve; wherein the rotary sleeve is connected with the mill head bracket through a bearing, one end of rotary sleeve is concentrically fixed on a belt pulley, a belt is arranged between the belt pulley and the output end of the mill head drive motor, the other end of the rotary sleeve is concentrically fixed on the facer, and the at least two small cutter bodies with the same blade are uniformly distributed on the end surface of the facer. The whirlwind envelope processing for various screws can be realized through a standard carbide blade; only a whirlwind facer can realize the cutting processing for all the screws of all parallel & homodromous twin-screw extruder, which greatly reduces the requirements on the cutting tool, omits the expensive tool sharpening equipment, and reduces the costs.
