Surface technique that accelerates the mass grinding and polishing of metal articles in roto finish equipment

摘要

Process for grinding and/or polishing metal articles in roto-­finish 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 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.
