It is known that a predetermined final product shape is obtained by performing primary processing (rough processing) such as lumped forging and secondary processing (finish processing) such as finish forging and rolling. Subsequently, an oxide film is removed from the rolled product by polishing or the like to obtain a rod-shaped material.

1 is a deformation centerless in which the rod-shaped material W is supported and placed on both sides thereof by a polishing wheel 102 and a rubber roller 103 which rotate in the same direction from each other, and the outer peripheral surface is polished by the polishing wheel 102 while rotating the rod-shaped material W. A polishing method (centerless method) is adopted.

（あばれ）の低減が安全上からも強く要望されていた。By the way, in the above-mentioned prior art, the material to be worked is not particularly stable in shape with a rod-shaped material after hot working, and the outer peripheral surface is further rotated while rotating the rod-shaped material. Since the polishing is performed, there is a problem that the rod-shaped material may run out during polishing and the outer peripheral surface cannot be polished well. This problem becomes more remarkable as the outer diameter or length of the rod-shaped material increases, and there has been a strong demand for reduction of the run-out (safety) from the viewpoint of safety.
