The utility model discloses a miniaturized high-rigidity multilateral cutting device. Device comprising a device body, a servo motor is mounted in the device body; a coupler is installed at one end ofthe servo motor, one end of the coupler is connected with a rotating shaft, a deep groove ball bearing is arranged on the side of the rotating shaft, a space ring is arranged on the side of the deepgroove ball bearing, a double-layer tapered roller bearing is arranged on the side of the space ring, a space ring set is arranged between the two tapered roller bearings, and a top sleeve is arrangedon one side of each tapered roller bearing. According to the utility model, the application of combining the tapered roller bearing and the deep groove ball bearing is adopted; the cutting rigidity is ensured; the appearance of the cutting device is more compact; the problem that the X-axis stroke of a machine tool is occupied due to the appearance is effectively solved, specifically, due to thefact that the two sets of ta
