Abstract
A method for finishing a surface of a metal component is carried out in a receptacle containing a quantity of non-abrasive media. The component is at least partially immersed in the media and a quantity of active finishing chemistry is supplied. The chemistry forms a relatively soft conversion coating on the surface. By inducing high energy relative movement between the surface and the media the coating can be continuously removed. The method may be carried out in a drag finishing machine.
