metal working
Metalworking Fluids (MWFs) are neat oils or water-based fluids used during the machining and shaping of metals to provide lubrication and cooling. Main groups depending on the final use are:
- Cutting fluids or coolants
- Metal-forming lubricants
MWF must lubricate and cool down a contact area between the tool and the metal work piece. Moreover, the formulation has to prevent corrosion, remove chips and clean the modified metal surfaces. The esters can be formulated as base oil but also as additives to improve antiwear performance.
Formulation types
- Neat Oil
- Semi-Synthetic (emulsions)
- Synthetic (water soluble solutions)
Formulation components
| Base Oil | Biocide |
| Lubricity or boundary lubricant | Fungicide |
| Emulsifier | Coupling agent |
| Anti-corrosion additive | Anti-mist additive |
| Extreme pressure /Antiwear additives | Water |
| pH buffer |
