ABSTRACT:
A system for removing particulates, formed as metal is machined, from coog and lubricating fluid. The system has a tank filled with fluid. The bottom of the tank slopes forward. The tank receives contaminated fluid at its top rear. The contaminants are swarf (chips removed from the workpiece) and fines (which come both from the workpiece and the grinder, borer, or drill). After the swarf is removed from the contaminated fluid by a magnetic filter, only fines remain. The fluid contaminated with fines flows from back to front in the tank, passing under a baffle projecting vertically downward from the top of the tank. A whoosh plate causes the fines to settle out into the tank, while uncontaminated fluid flows over the whoosh plate and is reused. The fines collect at the tank's bottom, from where they are pumped out and mixed with the magnetically-removed swarf for removal.
