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.

Abstract: An apparatus for precision shaving is provided. In one embodiment, the apparatus includes an endmill cutter, a base frame, and a motor adjacent to the base frame and having a shaft on one end. A coupler is positioned between the shaft and the endmill cutter. A positioning slide is housed within the base frame and a coupler frame and a first gear are fastened to the positioning slide. A second gear is adjacent to the first gear, the second gear having a set of first teeth and a set of second teeth positioned opposite the set of first teeth. The set of first teeth and the set of second teeth are separated by a gap.

Abstract: A system includes an abrasion component containing an abrasion pad configured to clean a faying surface of a nutplate and a shaft attached to the abrasion pad and configured to rotate the shaft and the abrasion pad during cleaning of the nutplate, which includes abrading the faying surface with the abrasion pad. The system further includes a base configured to attach to a pressure applicator, and the pressure applicator, which is configured to attach to the base, hold the nutplate such that the faying surface is capable of contacting the abrasion pad during the cleaning of the nutplate, and apply pressure to the nutplate such that the nutplate contacts the abrasion pad during the cleaning of the nutplate. Furthermore, the abrasion component is configured to rotate the abrasion pad within at least one of the base and the pressure applicator during the cleaning of the nutplate.
