Abstract
The invention relates to a method and an arrangement for cleaning cutting fluid used for metal machining. The cutting fluid is withdrawn from the collecting tank (1) at a metal cutting machine by means of vacuum and conveyed to a central cleaning plant by way of a container (3) connected to a vacuum pump. From the cleaning plant the cutting fluid is returned to the collecting tank (1) at the metal cutting machine. The cleaning plant may with advantage comprise a separation tank (6), where separation takes place by gravity and a centrifugal separator (8).
Claims7
The combination of a series of collecting tanks for respective metal cutting machines, a cutting liquid in each said tank for use in metal machining, a first pipeline having inlet branches opening into said tanks in position to remove therefrom only an upper layer of cutting liquid, a container into which the outlet end of said pipeline leads, a vacuum pump connected to said container for creating a vacuum therein to draw cutting liquid from said tanks into said container, means connected to said container for receiving cutting liquid therefrom and cleaning said liquid, and a second pipeline for returning cutting liquid from said cleaning means to said collecting tanks.
