Abstract
PURPOSE:To permit precision cut by one chucking, by a method wherein a boss for a working chuck is made concentric to an output shaft penetrating hole, penetrating from a ball bearing engaging hole on an inner peripheral wall toward an engaging part for mounting, and the outer diameter of the boss is made smaller than the same of the engaging part for mounting. CONSTITUTION:A boss 22 for a working chuck is made concentric to an output shaft penetrating hole 12, penetrating from a ball bearing engaging hole 10 on an inner peripheral wall toward an engaging part 14 for mounting, and the outer diameter of the boss 4 is made smaller than the same of the engaging part 14 for mounting. A case elemental body 21 for a stepping motor is prepared and the boss 22 for the working chuck is chucked by a collet chuck to rotate the elemental body 21 of the case and effect the precision cut of the outer peripheral surface 14a of the engaging part 14 for mounting at the side of an outer peripheral wall and the inner peripheral surface 10b as well as the bottom surface 10a of the engaging hole 10 at the side of the inner peripheral wall. Subsequently, the boss 22 for the working chuck is cut and removed at a boundary between the boss 22 for working chuck and the engaging part 14 for mounting.
