Metalworking fluid emulsion stability and base oil properties

Metalworking fluid emulsion stability and base oil properties

Prof. Thomas Norrby Nynas AB, Naphthenics TechDMS Dr. Pär Wedin Nynas AB, Naphthenics Research Ms. Linda Malm Nynas AB, Naphthenics TechDMS Emulsion stability is key to metalworking fluid usefulness. Nynas conducted an emulsion stability study comparing the properties of naphthenic and paraffinic type base oils. The study indicates that the naphthenic base oil emulsions display the highest stability.   Introduction Metalworking fluids (MWF) are used to aid the process of metal machining, mainly by providing lubrication of the workpiece and tool, by providing cooling and corrosion protection. Many different MWF formulations are needed for the vastly differing needs under varying operating conditions! In metal cutting, the ...
