Summary:The invention relates to the technical field of threading hole machining, and particularly discloses a threading hole machining method which comprises the steps that S10, a three-dimensional mathematical model is created for a workpiece to be machined; s20, a threading hole machining position, a threading hole cutting track at the threading hole machining position and a corresponding cutting angle are determined on the three-dimensional mathematical model; s30, a threading hole is cut in the workpiece to be machined according to the determined threading hole machining position and the determined threading hole cutting track; and S40, passivating the hole wall of the threading hole through a welding-wire-free argon arc welding process. The hole wall of the threading hole is subjected to high-temperature passivation by using a welding-wire-free argon arc welding process, so that the hole wall of the threading hole and the surfaces of the two sides of the workpiece to be machined are respectively chamfered, the
