The surface finish of the die determines the surface finish of the part. 1. This paper discusses using a non-abrasive, high density media in conjunction with an isotropic superfinishing (ISF) chemistry. join our mailing list. Gear 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. Key benefits of the isotropic surface finishing process. In the previous articles, 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. These parts experience extremely high temperatures and parasitic friction. 9 min. Unlike most. 2. The term isotropic superfinishingwas coined to differentiate a specific subset of superfinishing techniques based on the texture that is created on the surface of the component to which the technique is being applied. The term isotropy means uniformity in all orientations. 6 Poon and Bhushan7 demonstrated the influence of the resolution of the applied measurement equipment . S. Opening at 9:00 AM. 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. In gear mesh, the lubricant thickness is greatest across the pitch line where the system exhibits pure rolling action. From this first use of isotropic superfinishing on bearings, the process jumped into the gearing world via the motorsport industry. REM’s ISF ® Technologies are able to controllably remove the white layer from components like gears and have been used in this capacity for over 15 years. REM’s isotropic superfinishing technology is built around our proprietary processing and consumables. The process produces a uniform mirror-like finish on hardened steel parts that reduces friction, contact fatigue and stress risers. 2. 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. The REM™ processing compounds are high cost, proprietary, require special handling and disposal, and only typically available in large 55 gallon drums. Motorsport & Racing. It has been reported that metal-to-metal contact areas, if refined by isotropic superfinishing (ISF), will have a resultant isotropic surface. Brisbane Isotropic Surface Finishing. The Extreme ISF Process is capable of removing the extreme surface roughness, surface and near-surface defects (keyhole porosity and the like) inherent to. Available via outsourced processing or as a technology installation, REM’s Rapid ISF Process is ready to meet your high volume, low WIP manufacturing demands. “Isotropic superfinishing can absolutely be used as a quick fix to solve late stage design or in production issues,” Michaud said. ). 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.
