Abstract
A cleaning apparatus for small, ferrometallic, precision items, e.g., dental burs, includes a cabinet unit housing a plurality of magnets mounted on a motor driven, rotatable disc with the magnets being arranged and designed to provide a rotating, unipolar, non-uniform, magnetic field coacting with the items in which individual fields are induced and which provide for rotation separation and oscillation of the dental burs being cleaned in a solution within an appropriate container; a second group of magnets also mounted on a rotatable disc for rinsing of the cleaned dental burs; and a degaussing unit for demagnetizing the dental burs once cleaned and rinsed. A magnetic bur pick-up device allows for moving the dental burs from one area to the next without physical contact of the already cleaned burs.
