ISF Process is an ideal pre-coating surface for any wear-resistant coatings that be applied to bearing elements. “When you turn or grind a part, the depths of cut could range from 50-100 microns or higher,” Keshavan says. This achieves a surface that is super finished. REM’s isotropic superfinishing technology (ISF ® Process) significantly extends component life, increases resistance to stress corrosion cracking and improves laminar flow characteristics thereby minimizing airflow frictional and turbulence losses from stage to stage by airfoil planarization leading to increased turbine efficiency. . The days of early gearbox failure due to epidemic micropitting are largely in the past. Isotropic Superfinishing of S--76C+ Main Transmission Gears Bruce Hansen, Sikorsky Aircraft Corporation Mike Salerno and Lane Winkelmann, REM Chemicals, Inc. Whilst Additive Manufacturing is undoubtedly having a huge impact on the design and manufacture of rocket propulsion systems, most notably combustion chambers and nozzles, the Achilles’ heel of all AM process is currently as-built surface finish. In all cases, REM’s isotropic superfinishing processes increase the quality, performance, and value of the components to which they are applied. As shown, isotropic superfinishing has a positive influence on scuffing resistance. 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. Our patented and proprietary chemical and mechanical/vibratory finishing technologies allow for precision-controlled surface finishing of metal components via a subtractive process (Figure 3. This study showed how an isotropically superfinished gear with an Ra of 2-3 µin. . Headquarters: 325 West Queen. 08 μm. . 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. Our patented and proprietary chemical and mechanical/vibratory finishing technologies allow for precision-controlled surface finishing of metal components via a subtractive process (Figure 3.

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. In the ISF process, a chemical compound reacts with surface peaks, thereby creating a coating film. This process is discussed in the October column, “Isotropic Superfinishing,” and works by selectively removing the aforementioned peaks, forming larger and larger flat areas until all peak asperities.
