Abstract
The invention relates to a matrix liquid for producing machining suspensions, a machining suspension produced with the matrix and a method of fractionating the used machining suspension yielded after use. The invention also relates to a homogeneous mixture of a polymer or various polymers and water. The mixture can be used especially advantageously in all technical applications requiring a liquid with lubricating properties. In the present invention, a mixture of water and a thickening agent, respectively a polymer or a multiplicity of polymers, is utilized as the matrix liquid or lubricating liquid. The cutting grains can be separated very easily and quickly from the used machining suspension produced with this matrix liquid; for reuse. Less process water is required and the process water can be simply purified as there is no complicated getting rid of an alcohol charge.
