HARD DISK CARRIAGE, METHOD OR MACHINING A SWAGE HOLE INNER CIRCUMFERENTIAL SURFACE OF A HARD DISK CARRIAGE, BACKUP TOOL AND CLAMPING TOOL USED IN THE MACHINING METHOD, AND APPARATUS FOR MACHINING A SWAGE HOLE INNER CIRCUMFERENTIAL SURFACE OF A HARD DISK CARRIAGEABSTRACT OF THE DISCLOSURECenter portions of inner circumferential surfaces of swag holes of fins in a conventional hard disk carriage bulge out toward the inner side, and thus the force with which a head is attached to the swage holes decreases, making the attachment unstable. Inner circumferential edge portions of the swage holes of the fins sag when burrs, which develops in the carriage due to machining, are removed by a deburring process such as etching deburring or electrolytic deburring. The bulging portion that develops on the inner side with respect to the sagging portion is removed, thus flattening the inner circumferential surface to thereby increase the force with which the head is attached and held onto the swage hole.(Representative figures: FIGS. 2A, 2B and 2C)
