Subject field(s)
  • Machine-Tooling (Metallurgy)
OBS

The sulphur contained in an inactive oil is the natural sulphur of the oil and has no chemical value in the cutting fluid's function during machining. These fluids are termed inactive because the sulphur is so firmly attached to the oil that very little is released to react with the work surface during the cutting action.

Domaine(s)
  • Usinage (Métallurgie)
