7. A method for processing a cutting device using a numerically controlled tool, characterized in that: A cutting device comprising a CNC tool according to any one of claims 1 to 6, comprising the steps of: Step 1: The third threaded rod (48) is rotated by rotating the knob (51), driving the third connecting block (52) to move in the direction of the fourth clamping groove (49), thereby being able to adjust the position of the cutting motor (3) and the cutting blade (4) to adapt to tool bodies (2) of different lengths; after the tool body (2) is placed between the clamping blocks (37), the clamping blocks (37) initially clamp it under the action of the spring (44), and then the rotating ring (38) is rotated, and the rotating ring (38) moves toward the side close to the tool body (2), and under the cooperation of the third inclined surface (40) and the fourth inclined surface (41), the clamping blocks (37) stably clamp the tool body (2), facilitating cutting processing; Step 2: When the first motor (6) drives the rotating ring (38) to rotate, when the rotating plate (24) contacts the second connecting plate (25), the second connecting plate (25) drives the rotating plate (24) to rotate, and drives the first threaded rod (21) to rotate. The first threaded rod (21) cooperates with the threaded sleeve (20) to move toward the first adjusting block (13), and then drives the first adjusting block (13) to move. The movement of the first adjusting block (13) can drive the second adjusting block (14) to feed downward under the cooperation of the first inclined surface (15) and the second inclined surface (16), and then drives the cutting motor (3) and the cutting blade (4) to feed, and cuts and feeds the tool body (2) in the axial direction. The rotation of the first motor (6) drives the first gear (7) to rotate, and then drives the gear ring (8) to rotate, drives the cutting motor (3) to rotate, and the cutting blade (4) performs an annular cutting on the tool body (2); Step 3: When it is necessary to fine-tune the cutting direction of the cutting blade (4), turn the knob (33) to drive the second threaded rod (30) to move in the threaded groove (31), thereby driving the third connecting plate (27) to rotate around the first rotating shaft (28), thereby driving the cutting motor (3) connected to the third connecting plate (27) to rotate at an angle, and the cutting angle of the cutting blade (4) changes, and the cutting direction is fine-tuned. After cutting, the tool body (2) is removed and the next step of processing can be carried out.
