✅ Processing Steps:

A. Rough milling slots, fine milling slots
B. Rough milling semi-circular slots, fine milling semi-circular slots
C. Slotting with circular saw blade
D. Precise trimming of the back spindle cutting surface
E. Drilling, boring, tapping internal threads

✅ Key Controls:

(1) No machining marks on the outer periphery after fine milling.
(2) Both end faces need to be flat without tool marks.
(3) Tooth hole positions must meet design requirements.
(4) Surface roughness of internal threads.
(5) No machining marks or residual burrs on the bottom of the semi-circular hook groove.
