The embodiment of the invention discloses a manufacturing method and manufacturing equipment of a screw drill stator and the screw drill stator, and belongs to the technical field of machining. The method comprises the steps that the rolling spiral angle of a rolling wheel is determined based on the model of a target screw drill stator; the rolling posture of the rolling wheel is adjusted according to the rolling spiral angle; the rolling wheel is controlled to feed in the radial direction of the blank pipe according to the rolling posture; and in response to the fact that the radial feeding distance reaches the radial thread depth of the target screw drill stator, the rolling wheel is controlled to feed in the axial direction of the blank pipe according to the rolling speed, and the blank pipe is controlled to rotate at a constant speed according to the rotating speed and the rotating direction with the center line of the blank pipe as a rotating shaft. According to the method, the strength of the stator can
