A cleaning machine is described to remove contamination from components machined in clean-room environment assemblies that are conducive to static changes and where wet cleaning is prohibitive. The machine incorporates a rotating brush within a coarse vacuum supply to remove and extract particles. Electrostatic charge elimination is achieved by subjecting the brush to alternating high voltage pulses. The design allows in-process de-burring by selecting a brush of suitable geometry to deal with various radial positions machined, including narrow undercuts. The top plate of the machine is suitably apertured to act as a holding jig. The cleaning machine comprises a cylindrical housing 1 with a circular opening in the top plate 2 which acts as a locating jig for the workpiece 3 (shown hatched) which is to be cleaned.
