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. The performance benefits are well documented, and the list of flight certified new aircraft grows with each passing year. Isotropic surface finishing, (ISF) or superfinishing with chemically accelerated vibratory surface finishing (CAVSF) is an environmentally friendly, inexpensive process to reduce the stress risers, damaged material, and asperities from the metal surface. The various aspects of isotropic superfinishing and isotropic superfinishes that have been discussed in previous Materials Matter columns include how an isotropic superfinish lowers surface roughness, creating a unique surface texture; increases gear performance; and enables maintenance of full EHL over a wide variety of operating conditions. . This is a patented process, used not just for car transmissions, but also in aerospace, medical, and military applications; places where ultra-smooth metal surfaces are. The process of isotropic Super-finishing (or ceramic tumbling) reduces. The Isotropic Superfinish or ISF Process, henceforward referred to as superfinishing, is an alternative time and cost efficient method of gear refurbishment. 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. Gulf Islands (Southern) Kootenay (National Park) McBride. When metal components come into contact with each other, contact stresses and friction occurs which directly. During this stage, the vibrating action of the media removes marks which smoothes the surface to a mirror like state.
