Ball valve element machining equipment and machining method thereof

The invention belongs to the technical field of ball valve element machining, and particularly relates to ball valve element machining equipment and a machining method thereof.The ball valve element machining equipment comprises a supporting assembly, two side face grinding mechanisms and two inner wall grinding mechanisms are installed on the supporting assembly, and the two side face grinding mechanisms are symmetrically arranged on the left side and the right side; the valve element inner wall polishing device has the beneficial effects that the two side face polishing mechanisms and the two inner wall polishing mechanisms are arranged, and polishing of the inner wall or the outer surface of a valve element is controlled to be completed according to the difference of extrusion force of the two side face polishing mechanisms and the two inner wall polishing mechanisms on the valve element; polishing of the outer surface and the inner wall of the valve element is achieved, and polishing is more sufficient; a
