Finish machining forming equipment for metal connecting piece and forming process of finish machining forming equipment

The invention provides finish machining forming equipment for a metal connecting piece and a forming process of the finish machining forming equipment, and relates to the technical field of finish grinding machining. The four groups of working bearing platforms are distributed at a first working station, a second working station, a third working station and a fourth working station at intervals of 90 degrees, the working bearing platform at the first working station slides out of the vertical turntable under the driving of the push cylinder I and is connected to the bottom end of the feeding box, the grinding head II is used for grinding the side surface of a workpiece at the second working station, and the grinding head II is used for grinding the side surface of the workpiece at the third working station. And the supporting cavity face below the vertical rotating disc is driven by the jacking cylinder to ascend to support the workpiece, the third grinding head is used for conducting grinding machining on th
