摘要

To provide means for making a degree of the coaxiality of a recessed spherical seat and a rotating body favorable.SOLUTION: In a preparation process, a frame (10), a recessed spherical side (15), a protrusive spherical seat (13), a rotating body (16), an oscillation shaft (12) and a work holder (17) are assembled to one another, a laser head (33) is attached to the protrusive spherical seat (13), and a light receiving unit (38) is attached to the work holder (17). In a rotating-body centering process, an irradiation position of a laser beam (LB) to a laser irradiation face (41) is changed by rotating the rotating body (16) while radiating the laser beam (LB) emitted from the laser head (33) to the laser irradiation face (41), and a trajectory of the irradiation position is confirmed.SELECTED DRAWING: Figure 4
