A method for processing a cutting device using a numerically controlled tool, characterized in that: A cutting device comprising a CNC tool machining as claimed in any one of claims 1 to 9, wherein the steps include: Step 1: The third threaded rod (48) is rotated by rotating the knob (51), thereby driving the third connecting block (52) to move in the direction of the fourth clamping groove (49), thereby adjusting the positions 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 plates, the clamping block (37) initially clamps 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). Under the cooperation of the third inclined surface (40) and the fourth inclined surface (41), the clamping block (37) stably clamps the tool body (2) to facilitate 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, driving the first threaded rod (21) to rotate, and the first threaded rod (21) cooperates with the threaded sleeve (20) to move toward the first adjustment block (13), and then drives the first adjustment block (13) to move. The movement of the first adjustment block (13) can drive the second adjustment 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, driving the cutting motor (3) to rotate, and the cutting blade (4) performs 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) can be removed to proceed to the next step of processing.
