PUMICE MACHINES The pumice machines, stainless steel made, are suitable for copper surface preparation before dry-film application or other printing processes. Metal surface, also thanks to the support of dedicated brushes, is perfectly cleaned getting a proper roughness to facilitate a better dry-film adherence. Machines can alternatively use pumice or aluminium oxide. Many accessories are also available.
