ISF™ surfacesThe REM’s isotropic superfinishing technologies are value-adding and performance-enhancing improvements to conventional machining operations such as grinding and lapping. Isotropic superfinishing has been demonstrated by many studies that it can have positive influence on friction/heat reduction and surface fatigue life improvement for sliding/rolling contact elements such as bearings and gears. Isotropic Superfinishing of S-76C+ Main Transmission Gears Posted by Christina Michaud on Tuesday, November 19th, 2013 in Isotropic Superfinishing is a chemically accelerated vibratory finishing process that is capable of generating surface finishes with an Arithmetic Mean Roughness (Ra) 3 min. MXRR SUPERFINISHED & DLC COATED COMPONENTS. It is a suite of isotropic finishing and superfinishing processes design to accommodate large batch volume component processing. 04 µm (20 µin. A key question is: Why does an isotropic superfinish create a benefit to surface durability? Before considering the larger concepts of lubrication effects, one should simply visualize two surfaces in contact under load in a dry. With over 25 years experience in both classic and modern racing, Nova has. This isotropic finish requires no break-in, maintains cooler gearbox operational temperatures, generates no metal chips and most importantly, dramatically reduces the initiation of future pitting and/or metallurgical.
