REM’s Extreme ISF Process (a suite of isotropic superfinishing/polishing processes) has been shown to significantly improve Metal AM component fatigue life (matching machined component performance in some cases) and is capable of finishing the extremely challenging geometries that generative design and design for additive manufacturing. Isotropic superfinishing has been demonstrated by many studies that it can have positive influence on friction/heat reduction and surface fatigue life improvement for sliding/rolling contact elements such as bearings and gears. Since that time, it has become widely accepted as a solution for numerous gear failure modes and performance enhancements. B. Isotropic superfinishing and. Additive Manufacturing and Gears Posted by Danny Estrada on Wednesday, September 7th, 2022 in Binder jetting The 3DPC started the tour with binder jetting/binder jet-like companies 3DEO and Desktop Metal. While a freshly cut and lapped gear may appear plenty smooth to the naked eye, a look through a microscope reveals a surprisingly rough surface (as. This is precisely the feature that produces the unique characteristics of a perfectly machined surface. Oil inlet temperature was varied from 160 to 250 F. We have a range of machines to refine surfaces finish of 3D additive parts to finely ground components. Get optimum performance and durability for your engine & gearbox components.
