Isotropic Superfinishing of S--76C+ Main Transmission Gears. The original material is printed with permission of the copyright holder, the American GearIsotropic superfinishing (ISF) is able to produce 2–4 μin Ra surface finishes using a combination of vibratory media and surface conversion chemicals without modifying the profiles of aerospace quality ground gear teeth. Posted on Jun 11, 2013 at 10:43. superfinishing procedure that consists of immersing parts in an abrasive mixture of water, aluminum oxide powder and small zinc chips. Automotive power and drivetrain components typically transfer the energy from fuel combustions through a series of metal-to-metal mechanical components. As such, Isotropic Super-Finishing is the process of creating a uniform, non-directional (isotropic) finish on a metal surface. However any parts can be Superfinished that are not already coated like some wrist pins that come DLC coated. 4. The main transmission was assembled with accelerometers in various locations to best measure the amount of vibration generated by the isotropically superfinished gears, then run through the Acceptance Test Procedure (ATP), and ultimately a 200-hour. The isotropic superfinishing (ISF) process is used to repair the gear by removing surface damage.
