Abstract
A method and formulation for imparting a smooth finish to metallic components by subjecting the components to relative motion within a barrel or vibratory finishing machine, wherein the metallic components are immersed in a media which includes abrasive particles and an aqueous working solution of a metal finishing compound. The metal finishing compound includes a mixture of the tetrasodium salt of ethylenediaminetetraacetic acid, triethanolamine, the sodium salt of the amyl ester of sulfonated oleic acid (or the sulfate), together with a coco diethanolamine condensation amide modified with tallow fatty acid. The formulation is placed in aqueous solution, with the solution being capable of periodic or continuous partial removal for filtration to separate the aqueous solution from entrained abrasive particles.
