Punching and stamping of stainless steel is characterised as tribologically difficult due to galling caused by the brittle oxides and the large affinity of the base material to pick-up on the tool surface resulting in scoring of subsequently passing work piece surface. Until recently, the only lubricants able to impede galling in severe deep drawing, stretch forming and ironing operations were chlorinated paraffin oils, which are expected to be abandoned in near future due to environmental problems. In a national Danish research programme, 1994-99, two new lubricant systems have been developed as substitutes to chlorinated paraffin oils. Testing of these environmentally harmless lubricants under controlled laboratory conditions has shown very promising results and so has initial industrial tests at Danfoss, Grundfos and Volvo among others. In the present research programme ”Industrial punching/blanking and sheet metal forming – lubricants, mechanisms of lubrication and environmental aspects” running from 2000-2003 the development and testing of lubrication systems will be further studied in a co-operative project between Institut for Kemi, DTU, Institut for Produktion, DTU (in the following named IPT), Danfoss, Grundfos, RM Rich. Müller, Esti Chem and Houghton Danmark. Objectives The objective of the present project is to develop a general methodology for determination of the limits of lubrication in sheet metal forming of stainless steel. Furthermore development and testing of tailor-made surface topographies improving the resistance to lubricant film breakdown will be studied.
