ISF processing is capable of generating a surface finish with a 0. isotropic finishing Post by sbcharlie » Fri Aug 03, 2018 12:00 pm I was wonder if many of you know or use this process on internal engine parts and transmission gears. This paper will review the technique used to generate the improved isotropic surface finish and will additionally review some of the engineering advantages that can be imparted to metal-to-metal contact surfaces. UNTOUCHED by human hands… almost. However, wet etching also requires large amounts of chemicals, is less safe, and offers less control over the etch. Isotropic Finishing of Helicopter and Turboprop Gearbox Components William P. All etching processes are applied for removing material.
