Abstract

The right selection of lubricants in metal-forming, especially by deep-drawing, implicitly means that the role and importance of lubrication should be regarded as equal as the importance of other elements of the forming system. In selecting lubricants and zones of lubrication, the following demands must be fulfilled: - the existence of desirable friction resistance in all working-piece zones (control of metal-flowing), - reduction of metal to metal contact in critical zones, leading away of heat and reduction of tool-wear, - obtaining the desirable quality of the working-piece surface.
