ISF Services are available to meet any need: Capabilities: Chemically Accelerated / Isotropic (ISF), Chemical Finish / Conversion, Deburring / Deflashing, Honing / Superfinishing, Mass Finishing (Tumbling / Vibratory), Passivation. The days of early gearbox failure due to epidemic micropitting are largely in the past. As the aerospace and helicopter industries scrap many gears due to only minor surface damage, further. The Rapid ISF Process increases fuel efficiency and power density and is compatible with a ju. Chemically accelerated superfinishing is able to reduce the gear flank roughness to <0. ISOTROPIC IS NOTHING NEW - it has been around as long as vibratory finishing has but tweaking the process has lead to incredible advance in surface profile. REM’s ISF ® Process is an isotropic superfinishing technology that is proven to significantly increase the efficiency, performance, and life of metal to metal contact power transfer components for a range of Automotive component applications. 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. A chemically accelerated vibratory finishing (CAVF) method known as Extreme Isotropic Superfinishing_ (ISF_) developed by REM Surface Engineering (Brenham, Texas). 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. Forge Motorsport Billet Aluminum IWG Actuator (Improved durability and wastegate control/response along with higher boost levels) Parts cleaned via sandblasting, ultrasound & solvents (REM Chemical isotropic superfinishing process which significantly reduces friction, reducing heat & providing better inertia which is particularly helpful for. “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. Think about it this way: Reducing friction by smoothing those mating and sliding surfaces means less energy converted into heat, meaning more. An R a and R z as low as 0. Simply put, Isotropic Superfinishing significantly reduces the surface imperfections that remain after a Ring and Pinion Gear set is manufactured.
