In the previous article, we discussed the fact that chemically accelerated/assisted superfinishing, also known as isotropic superfinishing, was introduced into the gear industry more than twenty years ago. to 3. The term isotropic superfinishing was coined to differentiate a specific subset of superfinishing techniques based on the texture that is cre-. The REM system is ideal for gearbox components, ring and pinions, differential parts, and more. The Extreme ISF Process is capable of removing the extreme surface roughness, surface and near-surface defects (keyhole porosity and the like) inherent to. Motorsports components operate at extreme speeds under high torque requirements. Winkelmann, with 2 highly influential citations and 9 scientific research papers. join our mailing list. Superfinishing Motor Vehicle Ring and Pinion Gears. Part break-in cycles and bending fatigue resistance can be improved via isotropic superfinishing. Headquarters: 325 West Queen Street. After isotropic superfinishing, the gears were measured once again to determine the final surface roughness. Therefore, accurate classification of surface roughness is critical to ensuring that a gear performs as expected. The most common surface roughness parameter is Ra, the arithmetic roughness average of the surface. “If a gear design or system is experiencing failures or isn’t operating to the levels of performance to which it was specified and surface finish is a factor, then applying the isotropic superfinishing is. ASF Motorsport is a division of Precision Finishing Inc. Testing performed in- cludes thermal efficiency, gear tooth bending fatigue. Wesbar Vanquip Ewing Street . At West Coast Differentials, the process we use is chemically accelerated. A low Ra surface will be created on the parts as a result of the superfinishing process. Developed by REM Chemical, the ISF® process is a method of surface finishing metal components to a highly polished state (very low Ra surface roughness). This type of finish can be achieved with electropolishing or Metal DryLyte. A 3rd Generation family owned and operated buisness. ) Surface roughness is an important design factor in predicting and avoiding gear failure. Airfoils; Bearings; Blood Contacting Components; Gears; Hand Tools; Miscellaneous Applications; Nitrided Components; Precoating/ Plating Finishing;. The individual pieces and the collective mass are important to ensuring effective and efficient gear surface finishing results. Isotropic superfinishing is a term that, in the broadest sense, describes any process that is achieves a “superfinish” while also generating an isotropic surface texture. The REM ® Process is REM Surface Engineering’s original, break-through chemically accelerated surface finishing technology for traditionally manufactured components. The process gives the component an isotropic finish, that is, a non-directional, uniform surface finish with a low Ra obtained by lowering the roughness and increasing the compressions so as to enhance the performance of these. 1-7 An ISF surface does not have a unidirectional pattern but is random and non-directional3,8 (Fig.
