Isotropic Superfinishing, ISF® for short, is also known as the “REM process” and stands for chemically accelerated surface finishing. As such, Isotropic Super-Finishing is the process of creating a uniform, non-directional (isotropic) finish on a metal surface. The super-finishing allows to obtain surfaces with roughness even up to 0,01 μm and a non oriented surface texture; the isotropic surface, without preferential directions of the geometrico conformation, allows the components to be more resistant. Unlike polishing or finish grinding to create a smoother surface, isotropic finishing is a non-abrasive, chemical-mechanical process that removes surface peaks without affecting the surface valleys, so that the gear geometry remains unchanged and none of the case hardened surface is worn away. It is the process of altering a metal’s surface by adding, removing, or reshaping. Moreover, the isotropic surface imparts greater fatigue life. Since its evolution, the vibratory finishing process has produced an isotropic non-directional finish which improves the surface finish and edges of machined components. com 1-844-623-7998. isotropic finishing Post by sbcharlie » Fri Aug 03, 2018 12:00 pm I was wonder if many of you know or use this process on internal engine parts and transmission gears.
