Abstract (en)
[origin: DE19525407A1] A process for lubricating metallic workpieces during forming operations by drawing, deep-drawing or cold extrusion is characterised in that a non-homogeneous mixture of (a) 40 to 90 % by volume of a water-miscible cooling lubricant concentrate, (b) 10 to 60 % by volume of a non water-miscible cutting oil, (c) 0 to 25 % by volume of a sulphur-based lubricant additive and (d) 0 to 20 % by volume water is applied on the workpiece. The percentages of the constitutive elements of the mixture add up to 100 %.
