Rotate the rotor (100) by rotating the handwheel (132), so that the marking points on the rotor (100) to be drilled are aligned with the probes (31) in the positioning probe set (3). Accurately, record the scale position of the probe (31) on the platform (33) through the illumination of the supplementary light (311);

    Step 4, lock, move and adjust the support column group (12) below the rotor (100) and the support arm group (37) below the platform (33), and complete the alignment of the rotor (100) and the platform (33) support lock;

    Step 5. Adjust the rotor. Move the probe (31) upward along the avoidance adjustment groove (332) on the swing arm (32), fix the probe (31), and After adjusting the group (22) so that the drill (21) is aligned with the previously recorded scale position of the probe (31), the drill (21) is fixedly installed on the lateral movement module (22) On the sliding seat (221);

    Step 6. Drilling process, start the longitudinal movement module (23), so that the drill (21) moves towards the rotor (100), and process the rotor block (102) to be drilled.
