Top-quality crankshaft grinding with Hermes CBN crankshaft grinding wheels and Hermes aluminium oxide grinding film FB 637. To help its customers achieve those final values for concentricity, roughness depth and percentage contact area, Hermes supplies aluminium oxide grinding film FB 637, which is used in the form of cycled material on a roll and which has replaced conventional “stone honing“. The grinding material constantly being used new as a result of the cycling results in greater production effectiveness and simultaneously guarantees much greater process reliability.
Aluminium oxide grinding film FB 637 is extremely resistant to tearing and compression, and can be used under either oil or emulsion. This high-tech abrasive facilitates consistent application parameters and maintains narrow tolerance ranges for the surface values achieved throughout its entire tool life.
