Critical gear profiles, exotic alloys, ultra-low roughness requirements, we’ve got the experience to meet your surface finishing needs. Unlike most other failure modes, micropitting does not always proceed to component failure if left. The REM’s isotropic superfinishing technologies are value-adding and performance-enhancing improvements to conventional machining operations such as grinding and lapping. 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. I've got a crotch rocket engine to rebuild this winter, and at some. The isotropic superfinishing process refines carbon steel, stainless steel, titanium, and other alloy surfaces with non-hazardous, environmentally friendly. Durability in the form of pitting resistance is an area that has been extensively researched in regards to isotropic superfinishing technology.
