Abstract

Method and apparatus for fashioning or cleaning the internal surfaces of hollow metal pieces esp glassware moulds by etching and/or polishing, in which the hollow is filled partially with a charge and submitted to a complex rotational movement resulting from the relative rotation and/or oscillation about a secondary axis, itself rotating about a principal axis at speed. The charge may combine etchants and abrasives.
