The processing of such parts mainly includes end face processing, end hole system processing, end connection through hole, threaded hole and other structure processing, as well as milling, drilling and tapping of the installation surface of other parts in the middle. For the processing of such cylindrical parts, the commonly used scheme is to first use a lathe to turn the end face and end hole system, and then use a rotary boring machine or a gantry milling machine to drill and tap the end face, and complete the milling, boring and tapping processes in the middle of such parts, during which equipment such as a right-angle milling head and a rotary table are required to assist.
