ABSTRACT:
Apparatus for maintaining the condition of cutting fluids in a machine tool sump and for the removal of tramp oil from the cutting fluid has a pump to draw cutting fluid from the machine tool sump and transfer the fluid to an auxiliary tank where the fluid outlet is directed to drive a turbine wheel for rotation of a shaft and simultaneously aerate the cutting fluid. Drums on the shaft are partially submerged so as to be wetted by the tramp oil content. Wiper blades bear against the drum surfaces to strip the tramp oil from the drums as they rotate. A collecting trough is positioned below the wiper contact line to receive the tramp oil as it is stripped from the drum and drain it off to a waste container. In this manner, the cutting fluid is in constant circulation, even when the machine tool is idle.
