The invention discloses a process for accurately machining a three-jaw flange plate. The machining process comprises the following steps of 1, punching a center hole in the bottom end of a blind hole in the end tip of the bottom part; 2, turning the excircle of a neck body as well as the end surface and the back surface of a three-jaw plate at the end tip of a three-jaw part; 3, turning a blind hole in the end surface of the three-jaw plate at the end tip of the top part; and 4, drilling three holes in the end surface of the three-jaw plate at the end tip of the top part. Compared with the prior art, the process for accurately machining the three-jaw flange plate is simple in process flow and reasonable in design, one end of a workpiece is taken as a clamping end to start the machining, the previous flow of machining the two ends at the same time is replaced, the center hole of the workpiece machined in the way is accurate and consistent, the coaxiality of circles at the two ends is high, and the yield of the
