ABSTRACT:
Cutting fluid residues are removed from swarf such as turnings, borings, mill scale, grinding sludge, and the like, by washing the swarf with an aqueous detergent solution so as to emulsify the residues, thereafter removing the emulsified residues by entrainment in fluid stream, and then drying the swarf. If desired, the aqueous detergent solution can be reclaimed for further use by physically separating the emulsified residues therefrom.
