Title
(EN) A system and a separation for removing contaminants from cutting fluid
Abstract
(EN) The system 200 includes a tank 109 which receives swarf 110 and cutting fluid 112 from a machining process 102. A pump 118 extracts cutting fluid contaminated with swarf from the tank. A filtration system 120 removes at least some of the swarf before the cutting fluid is reused in the machining process. A separator 130 is arranged between the pump and the filtration system. The separator comprises a hydrocyclone 132 which receives the cutting fluid and swarf. The hydro cyclone separates the swarf from the cutting fluid by vortex separation before the cutting fluid reaches the filtration system. The filtration system may include a consumable medium such as a roll of paper, polyester, or viscose. A separator includes a hydrocyclone to receive cutting fluid contaminated with swarf and tramp oil from a machine process. The hydrocyclone separates the swarf from the cutting fluid and oil using vortex separation. The hydrocyclone transfers the cutting fluid and oil into an inlet of a chamber. The tramp oil is separated from the cutting fluid as it flows around barriers in the chamber by virtue of a difference in the relative density of the tramp oil and cutting fluid.
