A lubricant is applied to swage contact surfaces in a disk drive of the
type including a suspension arm connected to an actuator arm by a swaging
process. A preferred thin film lubricant may be applied to the contact
surfaces by immersion and draining, immersion and raising the part out of
the solution, localized spraying, or various deposition processes.
Application of the lubricant reduces chipping during de-swaging,
particularly with nickel plated metal components. Application of the
lubricant has also shown to improve gram load uniformity, reduce adverse
distortion to the actuator assembly and reduces torque out retention
values. Improved gram load uniformity enhances overall disk drive
functioning, reduced distortion preserves intended attitude and flatness
of the actions for assembly and reduced torque out retention values
improves reworkability of the disk drive.
