Abstract
The invention relates to a method of cooling and lubricating a metal-cutting rotating tool with a geometrically defined cutting element and/or the workpiece in the cutting zone. A coolant-lubricant and a carrier gas are fed separately into a tool shaft, brought together inside the rotating working spindle as close as possible to the cutting zone and directed via integral feed ducts onto the cutting element and/or cutting zone. Also disclosed is a device for applying this method. The coolant-lubricant and carrier gas are each introduced into a coolant reservoir completely or partially filled with a porous filler where they are mixed; the mixture is then fed directly into the cutting zone. Immediately behind the working spindle is a reservoir chamber filled completely or partially with a porous filler and comprising a substantially cylindrical closed casing with a coaxial feed aperture for the coolant-lubricant on one end face, radial feed apertures in the casing for the carrier gas and with an outlet aperture smaller than the casing diameter for the coolant-lubricant-carrier gas mixture in the end face of the casing opposite the feed aperture for the coolant-lubricant.
