1 Abrasives Everything from one place from the first grinding step to the last. Top-quality crankshaft grinding with Hermes CBN crankshaft grinding wheels and Hermes aluminum oxide grinding film FB 637

2 Hermes CBN crankshaft grindin where it really matters grindin When used for grinding the pins and journals on crankshafts, Hermes crankshaf grinding wheels with segmented CBN coatings are characterized primarily by very high profi le stability, something which is particularly apparent at the critica points on radii. Hermes new high-performance V42 bond allowed the grinding properties of the CBN coating to be improved signifi cantly. Hermes superabrasives for external cylindrical plunge grinding can be used at operating speeds of up to 160 m/s. Despite high stock removal rates, excessive thermal load on the workpiece is avoided. Example Hermes solution Specification 23B 151 Q7 V Operating speed 125 m/s Example dimensions 3A1-600/J275 x 40 x U20 - X8,5 Material Tempered steel (e.g. 42CrMo4) Service you will appreciate Competence as a system supplier, too including dressing tools Economical recoating of the basic bonded abrasive when CBN coatings are worn

3 wheels stand out the pins and journals Compared to conventional grinding wheels, this results in signifi cantly extended lives for abrasives, in turn leading to reduced tooling-up times and tool costs. The consequence for our customers is a more economical grinding process. Hermes supplies these high-tech grinding wheels with an external diameter of up to 750 mm. Source: Supfina

4 For the final grinding step Hermes aluminum oxide grinding film FB 637 Hermes abrasives also generate process cost benefi ts when fi nishing crankshaft bearing seats. To help its customers achieve those fi nal values for concentricity, roughness depth and percentage contact area, Hermes supplies aluminum oxide grinding fi lm 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. Aluminum oxide grinding fi lm 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.
