Electric spark roller texturing machine and texturing method

The invention discloses an electric spark roller texturing machine and a texturing method, and belongs to the field of machining equipment. The texturing machine comprises a machine tool body, a transverse moving device and an electric spark texturing device. The machine tool body is used for driving a roller to rotate, the transverse moving device is installed on the machine tool body and extends in the center axis direction of the roller, and the electric spark texturing device is installed on the transverse moving device and conducts electric spark texturing machining on the surface of the roller. The transverse moving device drives the electric spark texturing device to move in the center axis direction of the roller. According to the electric spark roller texturing machine and the texturing method, the electric spark texturing device is driven by the transverse moving device to move in the center axis direction of the roller, the electric spark texturing device moving transversely conducts electric spark
