In the previous article, we discussed the fact that chemically accelerated/assisted superfinishing, also known as isotropic superfinishing, was introduced into the gear industry more than twenty years ago. REM Isotropic Superfinished Crankshaft? Post Sun May 02, 2010 7:49 pm. Scuffing is the sudden failure of the lubricant layer during operating conditions, normally occurring under high load or high speed. A D-type Rubert-Song specimen that is in the same range of roughness as the surface being checked should be used for the calibration checking of precision gear flanks. REM’s complete isotropic superfinishing systems are robust equipment solutions for increasing the quality, volume, and reliability of the metal finishing and surface polishing processes at your company. The paper also reviews the technique used to generate ISF and some of the improvements that can be imparted to metal-to-metal contact surfaces. This is not a plating or coating process, but a true substrate surface enhancement that dramatically increase part. In parallel, REM worked on a range of modifications to its traditional isotropic superfinishing processes (Chemical-Mechanical Polishing/ CMP) to increase their effectiveness on AM components. 2 µin. produce an isotropic micro-texture on the surface that facilitated lubrication.
