Machining method for high-precision thin-wall high-temperature alloy material pipe connector

The invention discloses a high-precision thin-wall high-temperature alloy material pipe connector machining method which comprises the steps that firstly, a pipe connector assembly is clamped, a clamping plate is adopted to be welded to the pipe connector assembly, and the clamping plate comprises a base, a rib plate, a vertical plate and a pressing plate; a gap is formed between one side end face of the vertical plate and the lower end face of the mounting plate and then welded at intervals along the circumferential contour of the mounting plate, and the pressing plate is pressed on the upper end face of the mounting plate and then connected with a machine tool workbench through the base. Secondly, the pipe connector is milled and bored, milling objects are the inner molded surface and the outer molded surface of the pipe connector, and during milling, a rough milling, semi-finish milling and finish milling combined mode is adopted; a boring object is an inner hole of a pipe connector, and during boring, a c
