The present invention makes the process easy even for cylindrical parts that have an unbalanced sheet thickness and volume. In a spinning processing method of processing a rotor shaft 4, a material joining step, a material separation and deformation step, and a cylinder forming step are provided. The material joining step aligns the sheet surfaces and joins at least two sheets of metal plates 40a, 40b, 40c ( Figure 3 ). The material separation and deformation step rotates the metal plates 40a, 40b, 40c by a rotating shaft CL that is perpendicular to the surface of the sheet material and carries out separation and deformation by applying force at the coupling position on the periphery of at least two sheets of metal plates 40a, 40b, 40c ( Figure 4 ). The cylinder forming step applies force to at least one sheet of metal plates 40a, 40b and forms a cylinder along the rotating shaft CL ( Figure 5 ). |
