Improved gear design and manufacturing. Chemically Assisted Surface Enhancement, or CASE, is an isotropic superfinishing process which has been developed as a metal surface treatment to provide components with excellent bending and contact fatigue strength, together with resistance to high loading. Isotropic superfinishing has been demonstrated by many studies that it can have positive influence on friction/heat reduction and surface fatigue life improvement for sliding/rolling contact elements such as bearings and gears. The technological feasibility of the isotropic superfinishing (ISF) process, applied to Ti-6Al-4V parts produced by electron beam melting, is investigated in this paper by considering the. REM™ Isotropic Finishing. The days of early gearbox failure due to epidemic micropitting are largely in the past. Posted by Danny Estrada on Thursday, November 4th, 2021. Fehan was introduced to racing as a youngster in Buffalo, NY. Accelerated Surface Finishing is our proprietary Isotropic Superfinishing process, designed, engineered, and produced in house. Chino, Calif. What Is Isotropic Superfinishing? The term isotropic superfinishing was coined to differentiate a specific subset of superfinishing techniques based on the texture that is created on the surface of the component to. Unconventional isotropic superfinishing processes could be a solution to this problem since they can generate a low surface roughness on complex geometries. 2003 US. Cylinder Head & Block Refacing / Skimming. grinding, O. In the late seventies, REM began to experiment with the combination of chemically accelerated cleaning with abrasive mass-finishingCorrosion Repair via Isotropic Superfinishing. If the process is properly designed, it is also effective in reducing the surface waviness of a component (see Figure 2 and Figure 3). Isotropic superfinishing of gears, including ring and pinion gears, is an increasingly popular and effective method to reduce friction and improve. With a state of the art, purpose built factory and extensive investment in specially built machines, we are able to provide effective turn around times on parts of all types and sizes. It improves parts’ performance without changing the parts’ size and geometry. Moreover, evidence suggests that isotropic superfinishing imparts a finish that increases gear durability and service life in the field. ), integrally bladed rotors (IBRs), and blisks in the Power Generation, Industrial, and Aerospace industries. Developed by REM Surface Engineering, ISF, or “Isotropic Superfinish”, is a polishing treatment for machined metal components that eliminates the imperfections left over by the machining process. It was sctually started in the sixties for aerospace and now is relatively affordable for the average Joe. As each indentation is made, the surface will try to yield but is restrained by the substrate, introducing a residual compressive stress and removing any prior. 6 Poon and Bhushan7 demonstrated the influence of the resolution of the applied measurement equipment .
