Process and a device for lubricating and cooling cutting edges and/or workpieces in machining processes with chip removal, and their use in sawing machines

Abstract

In a process and a device as well as their use for lubricating and cooling cutting blade edges and/or workpieces in machining operations with chip removal, at least two immiscible fluids are fed to the cutting edges or workpieces. The two fluids include a first fluid for reducing friction between the cutting edge and a workpiece or chip, and a second fluid for cooling the cutting edge, workpiece, cutting edge support and, in case of need, the chips. A surprising increase of the lubricating and cooling effect can be achieved by the fact that the two fluids are stored or processed separately in separate vessels, and each fluid is conveyed from its associated container via a separate feed line to an applicator. Also, each fluid is applied from its associated applicator to the workpiece to be machined or to the cutting edge of the blade. During the relative motion of the cutting blade edge and the workpiece towards the penetration or chip removal section, the first lubricating fluid is applied first under formation of an adherent lubricant film and that then the second cooling fluid is applied on the spread lubricant film.
