A traditional machined surface has directionally oriented, parallel rows of surface asperities, whereby an isotropic superfinished surface (or an isotropic superfinish) has no asperity. to adapt our OFT for additively manufactured aluminum components (AL-6061RAM-2)[ix], as well as a Phase II toREM’s ISF ® Process, an isotropic superfinishing process capable of polishing the surfaces of power transmission gears and other metal to metal contact components, is able to improve the performance of off-highway equipment through its myriad of component benefits. The particles were<br />. Clearly removing corrosion that occurs in the manufacturing process is critical. aluminum oxide powder until a mirror-like finish is achieved. An Isotropic Superfinish (ISF) is produced by a patented chemically accelerated vibratory finishing process using non-abrasive media that is capable of surface finishing hundreds of parts per hour. Acct. By. The ISF-Process is a chemically accelerated vibratory mass finishing process patented worldwide by REM Chemicals, Inc, USA. *Shot-Peening AND REM Isotropic Surface Superfinishing of Entire Gearset *New HKS 4. Tweet on Twitter. Applications such as aerospace, helicopter and wind turbine gearing are increasingly requiring improved surface finishes and surface treatments to increase operational.
