The ISF® process: For superfine surfaces

ISF^® stands for Isotropic Superfinishing – chemically accelerated mass finishing. The patented process was developed by REM Chemicals, to finish high quality parts sparing the edges as much as possible. It is used primarily in the aviation and space industries, in motor and racing manufacturing, in medical technology and for high precision parts.

In the ISF^® process is an ideal combination of chemical and mechanical surface finishing. By using compounds in the acidic range, initially a thin oxide layer is applied to the treated components, which is then removed optimally from the components using selected abrasives. This creates a superfine finish (in the end finish roughness values of up to Ra = 0.02 μm, Rz = 0.14 μm), which leads to the rolling and running noises of components being reduced, reducing friction and thus the energy costs and increasing the service intervals and life.
