Mainly to remove the large margin and lay the foundation for the subsequent sequence of precision, the process requires milling the inner contour according to the part structure diagram shown, and pre-finishing the reference hole required for the precision. The aluminum alloy parts are precision-selected with the center hole as the reference hole, and the center hole is boring after the outer circle of the lathe, and the reference hole must be completed before the precision cavity.
