| description | The invention belongs to the technical field of aircraft engine repairing, and relates to a long and thin inner cavity deep hole splitting method for an aircraft engine. The method comprises the steps that firstly, the axial distance a between a tensioning pipe and the opening end of the air inlet side of an engine low-pressure rotor is measured to serve as the reference size for cutting off the tensioning pipe; the feeding amount is measured through a splitting device, and the splitting depth is calculated; the tool end of the splitting device enters from the engine air inlet side, the feeding amount b of the splitting device is measured, and when the difference between a and b is smaller than or equal to 0.1 mm, contact between a guiding core shaft end of the splitting device and the end face of the tensioning pipe is determined; then, high-temperature alloy deep hole cutting is carried out, the tensioning pipe starts to be split from a boss through the splitting device, and when the outer diameter of the t |
