Abstract:
A method for providing an increased torque retention characteristic in a joint formed using a swage mount for connecting a disc drive actuator arm to a load beam, said actuator arm and said load beam formed with respective swage openings, said swage mount having a base plate having a first side and a second side, said first side having a hub extending therefrom, said hub having an aperture extending therethrough, said method comprising the steps of:surface hardening said swage mount while maintaining a core softness for said swage mount;mounting said base plate to one of said actuator arm or said load beam so that said aperture of said hub is in registration with said swage opening of said one of said actuator arm or said load beam;inserting said hub into said swage opening of the other of said actuator arm or said load beam; andinserting a swaging element into said aperture thereby forming an interference fit between said swage mount and said other of said actuator arm or said load beam.
