Process for cooling and lubricating a cutting, rotating tool with a geometrically defined cutting edge and / or the workpiece in the machining area u. Machining spindle to carry out the process

摘要

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 (11) filled completely or partially with a porous filler (15) and comprising a substantially cylindrical closed casing (14) with a coaxial feed aperture (16) for the coolant-lubricant on one end face, radial feed apertures (17) in the casing (14) for the carrier gas and with an outlet aperture (18) smaller than the casing diameter for the coolant-lubricant-carrier gas mixture in the end face of the casing (14) opposite the feed aperture (16) for the coolant-lubricant.
