Single-disk reaming method of high-pressure rotor labyrinth disk

The invention discloses a single-disk reaming method of a high-pressure rotor labyrinth disk. A labyrinth disk is independently fixed on a clamp to ensure that the single labyrinth disk carries out single disk reaming when axial deformation is coincident to the assembly state; the labyrinth disk to be processed is independently assembled on the clamp and is tightly pressed by process bolts so as to ensure that the axial deformation of the labyrinth disk and the assembly state are coincident; the clamp in which the labyrinth disk is arranged is installed on a rock arm drilling machine, and then the process bolt on the labyrinth disk is removed every other process bolt; according to the size required to be processed, a proper cutter is chosen, installed on the drilling machine and fixed after centering; rough reaming is carried out on the loosened bolt hole of the labyrinth disk, and then fine reaming is carried out; manual feed is adopted for processing; the cutter rotation speed is 70-80 r/min; the process bo
