accressory burnishing - treatment apparatus for treatment , namely deburring , turning corners , polishing or cleaning of elements , namely metal , plastic , or ceramic elements . the apparatus is a self - contained hollow sphere , preferably made from substantially abrasion - resistant plastic , that works in conjunction with typically any traditional vibratory tumbling machine . the apparatus preferably has a screw - in port lid or closure member which opens to spherical inner space allowing insertion and later removal from the spherical inner space each of elements after treatment thereof , and removal of that was media necessary for the treatment . liquid and / or dry or wet media may be used with the elements in combination . the self - contained hollow sphere together with any media and abrasive and elements to be treated , locked therein by its male closure member , is placed into media and abrasives or the like contained for treatment by a vibratory tumbling machine where when activated , when the vibrations and tumbling action of the vibratory tumbling machine transfers its vibrations and movement to the closed sphere and its contents such that the treatment of elements within the sphere is accomplished on the isolated elements within the spherical inner space .
