Of most benefit on transmission parts as well as sliding and rotating surfaces. roughness can be removed via processes such as isotropic superfinishing, gear flank waviness can be a more challenging defect to remove depending on a range of factors including material removal tolerances and gear pitch. In-House Isotropic Superfinishing – Gear Finishing Service. “Isotropic superfinishing can absolutely be used as a quick fix to solve late stage design or in production issues,” Michaud said. Isotropic superfinishing removes light to moderate gear flank surface damage. The individual pieces and the collective mass are important to ensuring effective and efficient gear surface finishing results. REM Surface Engineering's ISF® Process Overview. What follows is a two-step process. Rear axle gears have been commercially isotropic superfinished using conventional vibratory finishing for many years, but this process has often been viewed as being too expensive and cumbersome for large. This is technically not a polishing process. Thread starter RobinH; Start date Nov 1, 2010; Replies 2 Views 7,726 R. A high dense media needs to be used for this process. Building Materials · Arizona, United States · <25 Employees. 1µm and Rz <1µm. Porsche / BMW / Mercedes /REM isotropic superfinishing. . 1). Typical examples of metal-to-metal components include bearings,. Courtesy of Tex Racing. January 29, 2009 10:09am. Figure 3 is of a set of small bearing races for isotropic superfinish testing.
