The rolling process is an important processing technology for improving the performances of thread shaft. In this paper, the axial self-infeed rolling process is investigated. The principle of the axial self-infeed rolling process is introduced and the performances of the formed thread shaft with copper T2 are evaluated. In addition, the major diameter of the formed thread shaft and the rolling torque during the axial self-infeed rolling process are studied. The hardness of the formed thread shaft with copper T2 is improved 74.2% and the microstructure is fibrous tissue in the bottom of the tooth groove. The size of the blank has greater impact on the major diameter and the forming torque than the rotating speed of the blank.
