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 The cutting fluid is withdrawn from the collecting tank (1) at a metal cutting machine by means of vacuum and conveyed to a central cleaning plant by way of a container (3) connected to a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).
