Abstract: The invention relates to apparatus and a method for preparing a fine oil mist, in particular to be fed into tool lubrication ducts of a CNC machine tool. The apparatus is turned ON/OFF solely using the standardized machine commands M08 (“Cooling lubricant ON”) and M09 (“Cooling lubricant OFF”). The control/regulation of the tools' aerosol supplies then will be fully automatic. It involves—contrary to known quantitative regulations—a simple regulation by means of aerosol pressure values. When starting the apparatus or following a change of tools, all aerosol pumps are operating, including, where tools exhibit cross-sectionally large boreholes, an oil over-enriching pump. At least one aerosol pump operates when regulated within a range of supply pressures.

Abstract: A device for producing a fine oil mist for preferred use in the lubrication of tools used for machining metal includes a vapourising chamber into which a supply line containing oil and air under pressure enters. The oil and air is sprayed through a vapourising nozzle into the vapourising chamber to form the mist. The mist travels from the vapourising chamber into the second chamber through a connection therebetween located in the vapourising chamber at an end opposite the end at which the vapourising nozzle is located. The mist travels through the second chamber and enters an outlet line where the mist is conducted from the device to a place of lubricating application.
