At present, FZG gear testing helps determine the impact of superfinishing on the gear's micropitting load capacity. By. The ISF process uses polishing technologies that are chemically accelerated to generate extremely low Ra (<4 μin or 0. Martin McCormick - August 12, 2016. Isotropic Superfinishing for Gear Repair for Helicopters and Wind Turbinesisotropic surface NASA SPINOFF – Some Engineering Is Only Skin Deep Posted by Danny Estrada on Monday, January 31st, 2022 inGear Repair for Helicopters and Wind Turbines via Isotropic Superfinishing Posted by Justin Michaud on Tuesday, June 6th, 2017 in The wind turbine, aerospace, and helicopter gear industries recognize the importance of surface finish and surface texture for maximizing component and system performance. Catalano1 & Paolo C. Probably (as long as the cost is acceptable) I will only perform the isotropic superfinishing treatment because nitriding requires special attention and knowledge of the metal alloy of the shaft, the heat treatments it has previously undergone, the desired depth of treatment, etc. Simply put, Isotropic Superfinishing significantly reduces the surface imperfections that remain after a Ring and Pinion Gear set is manufactured. Isotropic superfinishing is an ideal process for repairing damaged gear flanks and bearing surfaces found on used wind turbine gears. Is It Possible To Finish Vintage Parts Using The Isotropic Superfinishing Machine? 10. January 22-23, 2024. The beauty of the ISF® Process, isotropic superfinishing, is that a completely non-abrasive media having a density of 125 lbs/ft3 can be used. ' BENDING FATIGUEIsotropic superfinishing employs high-density, non-abrasive media to wipe, not abrade, surface asperities when used with a chemistry that forms a soft conversion coating. The isotropic superfinishing (ISF) process is used to repair the gear by removing surface damage. Processes such as isotropic superfinishing can generate a very low surface roughness on complex geometries through a planarization mechanism. REM’s ISF ® Process, an isotropic superfinishing process capable of polishing the surfaces of power transmission gears and other metal to metal contact components, is able to improve the performance of off-highway equipment through its myriad of component benefits. 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. The machine makes use of vibratory technology and combines it with highly-dense media. 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. ~ncreasing demands for higher product quality combined with pressure for. 1 μm Ra), micro-textured surface that is isotropic (or non-directional) in nature. 3).
