Mass grinding and polishing of metal articles in rotofinish equipment

Abstract

Process for grinding and/or polishing metal articles in rotofinish equipment, in which (a) an adjusted quantity of said articles, which have a metal surface roughness that is higher than required for the finish, usually larger than 5 .mu.m in AA (i.e. arithmic average); are introduced to a rotofinish apparatus and rotated for some time with (b) an adequate quantity of chips suitable for grinding and/or polishing the metal articles to be treated and (c) a compound that promotes grinding and/or polishing comprising one or more organic acids, wherein the compound is an organic acid or mixture of organic acids or solutions of organic acids in a concentration suitable for grinding and/or polishing the metal articles, and in that the grinding environment also comprises a finely divided metal or alloy with an oxidation potential greater than zero.
