Abstract: |
The stagger forward spinning technology is adopted according to the structural characteristic of a small diameter super-thin cylindrical tube. Three kinds of the spinning forming processes of roughcast are simultaneously tested. By the spinning forming process validation, the optimal scheme is the processing of 5mm roughcast two-pass spinning forming. Contrast to the other two schemes, its advantages are simple working procedure, high precision and low cost. |
