The Supfina Spiro fine-grinding series always offers the right system for your requirements. The alloy is designed for strength, creep resistance, and. 5 wt% of Nb, 2. Isotropic superfinishing processes might allow surface finish improvements without alterations to the geometry of the additive manufactured-parts. 75201 Kojetin. Isotropic Superfinishing is a chemically accelerated vibratory finishing process that is capable of generating surface finishes with an Arithmetic Mean Roughness (R a )< 3 min. Additive manufacturing (AM) processes allow complex geometries to be produced with enhanced functionality, but technological challenges still have to be dealt with, in terms of surface finish and achieved tolerances. Additive manufacturing (AM) processes allow complex geometries to be produced with enhanced functionality, but technolog-. We have legacy part traditionally made from 9310 AQ steel, vacuum carburized and shotpeened. ISF® – Isotropic Superfinishing is a chemically accelerated finishing method developed by REM Chemicals, that generates a non-directional low Ra surface. This process entails mass loss, isotropic volume shrinkage and densification of the material.
