Developed by REM Surface Engineering, ISF, or “Isotropic Superfinish”, is a polishing treatment for machined metal components that. The REM’s isotropic superfinishing technologies are value-adding and performance-enhancing improvements to conventional machining operations such as grinding and lapping. The REM’s isotropic superfinishing technologies are value-adding and performance-enhancing improvements to conventional machining operations such as grinding and lapping. is the answer to your Metal AM post-processing surface finishing needs. All Materials Matter Tooth Product Hot Seat Q&AEvaluation of Isotropic Superfinishing on a Bell Helicopter Model 427 Main Rotor Gearbox Posted by Christina Michaud on Tuesday, November 19th, 2013 inScuffing is the sudden failure of the lubricant layer during operating conditions, normally occurring under high load or high speed. , Southington, CT 06489 For more information, contact: William P. Nitriding is accomplished by gas, salt, or ion nitriding. 7 likes · 1 talking about this. Isotropic superfinishing is a process that produces a smooth (typically < 0. As a polishing process, the REM Process has been shown to be the. The highest hardening is achieved with 1 percent aluminum. From this first use of isotropic superfinishing on bearings, the process jumped into the gearing world via the motorsport industry. This process was applied to the third stage spur bull gear and mating pinions along with the second stage bevel gears of a Sikorsky S-76+ main gearbox. Isotropic superfinishing (ISF) is able to produce 2-4 ÎĽin Ra surface finishes using a combination of vibratory media and surface conversion chemicals without modifying the profiles of aerospace quality ground gear teeth. The CMP process works by exposing an AM component to an alloy-matched chemical solution designed to react with the component’s surface in. The wind turbine gearbox industry has also used isotropic superfinishing as a method of repairing damaged gears for over a decade. · Prevents micro and. This study showed isotropic superfinishing technology increased a gear’s resistance to contact fatigue by a factor of three, and increased bending fatigue resistance by at least 10 percent. REM’s business approach is to develop long term, deep customer partnerships to help you succeed in your business goals. 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. ISF Process is an ideal pre-coating surface for any wear-resistant coatings that be applied to bearing elements. FWD offers Superfinishing for all Motorsport - motorcycle racing, motor car racing, rally sport, drag racing, Motocross, Super moto. Sunshine Coast. Event: Motorsports Engineering Conference & Exhibition ISSN: 0148. If all of the raw gears placed in the equipment are. Home; Features; Profiles; Departments. The result is a smooth, burnished surface that polishes to a mirror-like finish. Airfoils; Bearings; Blood Contacting Components; Gears; Hand Tools; Miscellaneous Applications;. These steels are usually quenched and tempered prior to nitriding. The main stumbling block to overcome was a perception that a low Ra value generated by Isotropic Superfinishing might lead to scuffing, especially if the black oxide coating is eliminated, and deeper yet, would the gearbox survive the mandatory loss of lubrication test requirements. Accelerated Surface Finishing. Isotropic superfinishing represents an ideal, gentle, and controlled surface finishing solution to maximize the performance and potential of nitrided surfaces. REM ISF is used extensively at the highest levels of motorsport (F1, WRC, Nascar). 04 µm (20 µin. Simply put, Isotropic Superfinishing significantly reduces the surface imperfections that remain after a Ring and Pinion Gear set is manufactured. Polishing and superfinishing processes can also be used to finish metal AM parts. Founded in 1965 in Southington, CT by Robert Michaud, REM Surface Engineering is a family-owned company that has proudly been serving our partners and. The military and motorsport industries developed isotropic superfinishing in the 1990s specifically to resolve these problems. Chemically accelerated superfinishing is able to reduce the gear flank roughness to <0. The second issue is that both Ra and Rq provide equal weighting to the respective peaks and. Isotropic superfinishing is a process that produces a smooth (typically < 0. Abstract. The ISF Process is capable of polishing parts weighing over 10,000 lbs.
