Improvement of hydraulic semi-automatic lathe
The parts shown in Fig. 1 were clamped to the inner hole by a tube tube, and the outer circumference was turned on a CA7620 hydraulic semi-automatic lathe, and the two knurling grooves were turned on the C618 lathe. It has been improved so that the turning outer circle and the knurling groove are all completed on the CA7620 hydraulic semi-automatic lathe.
