Abstract:
A system includes an abrasion assembly containing one or more abrasion pads configured to clean a faying surface of multiple nutplates, and a shaft attached to at least one of the abrasion pads and configured to rotate some or all of the abrasion pads during cleaning, wherein cleaning includes abrading the faying surfaces with the abrasion pads. The system also includes a base configured to attach to a pressure applicator, and a pressure applicator configured to attach to the base, hold the nutplates such that the faying surface of each nutplate is capable of contacting one of the abrasion pads, and apply pressure to the nutplates such that each of the nutplates contact one of the abrasion pads during the cleaning. Furthermore, the abrasion assembly is configured to rotate the abrasion pads within at least one of the base and the pressure applicator during cleaning.
