It is a suite of isotropic finishing and superfinishing processes design to accommodate large batch volume component processing. Isotropic superfinishing is a repeatable and robust process. The described effort was undertaken to assess the impact of the isotropic superfinishing (ISF®) process on the corrosion resistance of a variety of gear steels. Available via outsourced processing or as a technology installation, REM’s Rapid ISF Process is ready to meet your high volume, low WIP manufacturing demands. “Removing that amount of material in a short amount of time requires lot of energy, and the part heats up. It would not be appropriate to treat those. Whether your needs are to improve the fatigue life of a rotating turbine engine component or to obtain a jewelry level finish on a decorative component, REM Surface Engineering and our Extreme ISF. The technology, economy, and environmental sustainability of isotropic superfinishing applied to electron-beam melted Ti-6Al-4V components E.
