Abstract: A process for the cutting or non-cutting forming of metals using two cooling lubricants, wherein an oil or a first emulsion having an oil content of at least 10 wt. % is applied to the workpiece, as a first cooling lubricant, at the tribo-zone and, at the same time, an oil-free cooling lubricant or a second emulsion that is an oil-in-water emulsion having an oil content of less than 10 wt. % is applied, as a second cooling lubricant, adjacent to the tribo-zone. Depending on the metal-working technique, a two-component nozzle is preferably used for supplying the first and second cooling lubricants, the jet of second cooling lubricant surrounding the jet of first cooling lubricant concentrically. Alternatively, it is possible to supply the first cooling lubricant directly to the tribo-zone through channels in the tool, while the second cooling lubricant is applied at the periphery.
