Metalworking Fluids—Fluids that are involved in metalworking procedures, including straight oil, soluble oil, semisynthetic oil, and synthetic oil. 

A grinder test was developed to correlate the mist reduction observed in the spray pattern analysis test with an actual metalworking operation. Both a semisynthetic which contains 10% emulsified oil and a synthetic metalworking fluid which contains no mineral oil, were used during the machining of steel bar stocks. 

The differences in mist suppression performance for the polymer types tested may be attributed to either the solubility variations of the polymers in the two types of metalworking fluids and/or to interactions of the polymer with components in the metalworking fluid. PEO polymers had initial mist suppression performance in the 10% semisynthetic fluid even though there was a loss in performance after short time period of machining. However, in synthetic fluids these polymers generated more mist than the baseline. The solubility of the PEO polymers in these fluids was not determined therefore, it can not be ascertained whether the polymers were in solution... 

A 10% semisynthetic metalworking fluid was additized with 200 ppm of a 2 million MW PEO polymer and Figure 6 depicts the percentage of mist reduction versus high pressure spraying time. Initially, 40% mist suppression was measured but within 0.5 hr this dropped to a 60% increase in measured mist. An additional 300 ppm of the 2 million MW PEO polymer increased the level of mist to 70-80% over the baseline.
