| abstract |
The invention relates to a method for cutting- or non-cutting shaping of metals using two cooling lubricants. A first cooling lubricant in the form of an oil or a first emulsion with an oil content of at least 10 weight % is applied to the tribozone and a second cooling lubricant which is an oil-free cooling lubricant or a second emulsion, representing an oil-in-water-emulsion having an oil content of less than 10 w.- %, applied to the workpiece at the level of the tribozone. Depending on the processing techniques used, a two-component nozzle is preferably used to apply the first and the second cooling lubricant. The jet of the second cooling lubricant surrounds the jet of the second cooling lubricant in a concentric manner. Alternatively, it is possible to introduce the first cooling lubricant directly into the tribozone via channels in the tool. The second cooling lubricant can be applied at the periphery. Drip-off cooling lubricants are collected together in a container where phase separation into a first and a second cooling lubricant occurs. The invention also relates to an apparatus for performing the above-mentioned whereby said apparatus consists of two containers. The phase which is separated off from the first cooling lubricant in the first container is added to the second container to enable complete phase separation. |
