Machining method for workpiece with thin-walled end face

The invention discloses an end face thin-wall workpiece machining method, which relates to the technical field of machining, and comprises the following steps: machining a blank workpiece into an inner hole shape required by a drawing along a first end of the blank workpiece; the periphery of the workpiece is fixed through a machining tool; drilling the second end of the workpiece; the second end of the workpiece is roughly bored, and radial machining is started from the center of the end face during machining; fine boring is conducted on an inner hole of the second end of the workpiece, and radial machining is started from the end face center during machining; and detecting whether the processed product meets the size requirement of the workpiece or not. By means of the special machining method for the end face of the workpiece in the machining process, it is guaranteed that deformation of the workpiece is reduced to the minimum, the tolerance size of the workpiece is guaranteed, and the design requirement o
