Embodiment 1
[0020] Embodiment 1: as figure 1 , figure 2 and image 3 As shown, a machining method of a turbine shaft comprises the following steps: (1) roughing the outer circle, lightening the small end of the optical axis 1 and punching the center hole 2; (2) balancing the rough movement; (3) The balance amount is corrected by the eccentricity of the center hole 2 of the optical axis and the center hole 3 of the turbine end; (4) taking the corrected center hole 2 of the optical axis and the center hole 3 of the turbine end as the reference, the outer circle of the optical axis 6 is used, and the total length of the optical axis of the center frame is used , re-drilling the center hole of the optical axis; (5) Use the center hole of the top optical axis to semi-finish the outer circle of each level; (6) Heat treatment and annealing; (7) Grinding the outer circle and end face of the turbine; (8) Flaw detection inspection; (9) Machining 8 R grooves at the root of the turbine shaft; (10)...
