Title:An Evaluation of the Colloidal Stability of Metalworking Fluid
Author(s):Rajagopalan, Nandakishore; Menniti, Adrienne; Kramer, Timothy A.; Clark, Mark M.
Subject(s):Metalworking fluids -- Recycling
Abstract:Metalworking fluids are used for cooling, lubrication, and corrosion control in the metal products industry. As of the mid-2000s, many manufacturers were using filtration or centrifugal systems to remove impurities from metalworking fluids to recycle used fluid back into their production line.

Knowing the quality of the metalworking fluid in the recycling system is important for maintaining the machining tools and eliminating metal chips and shavings. Measuring turbidity to calculate the stability of the metalworking fluid is a fast and easy experiment; however, does that test accurately depict the status of the metalworking fluid system?

ISTC’s Kishore Rajagopalan and colleagues from the University of Illinois and Texas A&M University experimentally tested three different turbidity methods to see if the models accurately described the true stability of the metalworking fluids.
