The invention has a turnback roll which can transfer and guide a polishing tap in a tangential direction of a pressure contacting roll, a vertical oscillation mechanism which linearly oscillates the pressure contacting roll in a tangential direction of a ball groove while being orthogonal to a rotating axis line, and a horizontal oscillation mechanism which linearly oscillates the pressure contacting roll in a direction of a rotating axis line toward both inner side surfaces of the ball groove. The ball groove can be securely polished by the polishing tape on the basis of the continuous or intermittent transfer of the polishing tape and the linear oscillating motion of the ball groove. It is possible to improve a polishing precision, it is possible to improve a surface roughness of the ball groove and it is possible to improve a polishing workability of the ball groove.

Method for polishing ball screw and ball screw polishing apparatus
A method for polishing a ball screw comprising a screw shaft defining a screw axis. The screw shaft is formed with a screw groove. The method comprises the steps of: rotating the screw shaft at a rotational speed about the screw axis; conveying a polishing tape having a polishing portion traveled around an outer peripheral surface of a pressing roller, the press roller being configured to rotate about a rotational axis; guiding the polishing tape such that the polishing portion is traveled around the outer peripheral surface; pressing the polishing portion against the screw groove; tilting the pressing roller such that the rotational axis is aligned with a lead angle; oscillating the pressing roller linearly along the rotational axis; moving the polishing tape at a moving speed in a direction parallel to the screw axis; and synchronizing the rotational speed with the moving speed based on a lead.
