The process is designed to remove the peaks on the surface and allow the valleys (or. Jeffrey Bell is president of Precision Finishing Inc. . GEOLOG International. Learn commonly asked question about isotropic finishing, the process of reducing discernible marks, lines or patterns in the molding process. Vibratory finishing is a type of mass finishing manufacturing process used to deburr, radius, descale, burnish, clean, and brighten a large number of relatively small workpieces. About REM Isotropic Superfinishing (REM ISF®) Process -. Regardless of the technique employed, a unidirectional polishing pattern is. In contrast to isotropic etching, anisotropic etching applies unequal amounts of etching and responds to specific directions. The REM process combines the use of a chemical additive with a non-directional mechanical finishing process that accelerates the finishing process and produces low.
