For the final grinding step.

Hermes aluminum oxide abrasive film FB 637 

Hermes abrasives generate process cost benefits when finishing crankshaft bearing seats.

To help its customers achieve those final values for concentricity, roughness depth and percentage contact area, Hermes supplies aluminum 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.

Aluminum 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.

The benefits for you:

  • The highly tear-resistant and even polyester film guarantees constant parameters of application during precision grinding operations
  • Closer ranges of tolerance in the coefficients of surface roughness benefit precision grinding, because of the film backing which is resistant to compression
  • An excellent grain sharpness with bond strength leads to high abrasion of material
  • Very good tool life
  • Shorter operating times
  • Oil and emulsion resistant
