Federal Firearms Licensee (FFL)For this reason, Arrow offers the capability of Isotropic Superfinishing. By: Nathan Michaud. What follows is a two-step process. 1 µm or less in 4 minutes. At West Coast Differentials, the process we use is chemically accelerated vibratory surface finishing. This is technically not a polishing. 7881. More recently, they funded a loss of lubrication test of an. Superfinishing. Isotropic superfinishing (ISF) machines use a non-abrasive process consisting of mass finishing or tumbling media, combined with chemicals, that convert a surface layer on the part into a soft compound easily removed by finishing media. S. For the case in which only one gear (pinion) is coated, the isotropic superfinished surface shows the highest potential concerning pitting fatigue. This is not a plating or coating process, but a true substrate surface enhancement that dramatically increase part. The isotropic surface generated is unique when compared to even the finest honing and lapping in that it has no directionality and a final Ra < 0. If the process is properly designed, it is also effective in reducing the surface waviness of a component (see Figure 2 and Figure 3 ).
