... of metalworking fluid useful life. An oil/water partition coefficient and mass balance based model is derived that is capable of accounting for the effect of tramp oil induced extraction of metalworking fluid components. After developing general expressions for the predictive model, the magnitude of extraction...

..., particulates, and tramp oils that contaminate metalworking fluids (MWFs). Consequently MF has the potential to reduce health risks and extend MWF life in the machine tool industry. This research assesses the productivity of ceramic membrane filters during filtration of synthetic MWFs and examines...

... additive to constrict pores. In contrast to the lubricant additive and defoamer, base fluid flux decline observed after specialty additive exposure cannot be accounted for by adsorption leading to pore constriction. [S1087-1357(00)01203-X] Mahdi , S. M. , and Sko¨ld , R. O. , 1991...

... in shape, the resulting dimpled tool surface is covered with an interpolating layer of material. The pins can be reset to their lowest position by either withdrawing hydraulic fluid or pushing them down with the setting platen.
