Isotropic Superfinishing is the mass finishing of parts with a combination of chemicals and friction stones to reduce the surface roughness. Nov 1, 2010. Discussion in 'Airheads' started by Hook74, Sep 7, 2021. It is capable of generating a surface roughness average as low as Ra - 0,02. Many of these independent shops have been providing access to REM Surface Engineering’s revolutionary isotropic superfinishing technology for racing and. As each indentation is made, the surface will try to yield but is restrained by the substrate, introducing a residual compressive stress and removing any prior. The attrition of this media is nearly nil, typically 0. is the answer to your Metal AM post-processing surface finishing needs. Processes such as isotropic superfinishing can generate a very low surface roughness on complex geometries through a planarization mechanism. It is well documented that isotropic superfinishing automotive rear axle gears can play a significant role in reducing these emissions.
