Abstract

A method of reducing debris within an E-block of an actuator assembly in a disc drive is provided. A manufactured E-block is first provided for tooling. The E-block has a central bore with an inner diameter and a bore surface. A hardening member is then provided with an outer diameter that is larger than the inner diameter of the bore surface. The hardening member is pressed through the central bore so that the hardening member compresses and deforms the bore surface. As the hardening member deforms the bore surface, the bore surface becomes substantially smooth and hard.
