The invention discloses a boring method for modular long-distance group holes. The boring method is characterized in that process windows are arranged on a workpiece according to the positions of coaxial group holes in the workpiece; auxiliary supporting frames are positioned and installed on the workpiece and correspond to the process windows; guide sleeves on the auxiliary supporting frames enter the workpiece through the process windows to support boring rods at a plurality of points; positioning and mounting surfaces of the auxiliary supporting frames are a top surface and side surfaces machined at the top part and the side parts of the workpiece; fixing and mounting screw holes of the auxiliary supporting frames are arranged on the top surfaces; the boring rods adopt the design of uniform outer diameters and modular lengths; and the boring rods and the guide sleeves can be used in combination with different auxiliary supporting frames according to machining requirements. In the invention ...
