Upon receipt at GRI, the gears appeared to meet the surface finish requirements, but they retained the black conversion coating as shown in Figure 2. The top picture is straight off the machine, and the bottom picture is after centrifugal isotropic finishing. Simply put, Isotropic means “having uniform physical properties in all directions”. S. REM ISF Isotropic Microfinish. RE: splines are tight in bevel gear Tmoose (Mechanical) 27 May 15 12:26. This limits how much they can reduce. At current stage, this method cannot directly replace the final finishing step, but it can serve as a competitive semi-finishing approach for optical surface of synthetic quartz. Each manufacturing. 5 μ m spacing and 20-nm height shows a rms roughness of ∼ 6. The surface roughness could be further reduced to less than 0. REM Surface Engineering Mechanical Or Industrial Engineering Southington, CT 1,806 followers Unlock Improved Performance Results With REM's Isotropic Superfinishing and the ISF® Surface. Surface finishing: Bekaert offers cleaning, batch heat treating, plating and isotropic surface finishing options. The REM ® Process is REM Surface Engineering’s original, break-through chemically accelerated surface finishing technology for traditionally manufactured components. Surface perfection is an art mastered by few, and ISO Finishing is the true maestro. All parts are individually inspected and hand deburred for quality assurance.
