    Research output: Contribution to journalJournal articleResearchpeer-review


    Punching/blanking is one of the tribologically wise most severe metal forming processes.Insu $cient lubrication leads to heavy pick-up of work piece material on the punch stem,bad tolerances and eventual breakdown of the punch due to excessive backstroke force,especially in case of tribologically di $cult work piece materials like stainless steels.For this group of materials few alternatives exist as regards appropriate lubricants and many companies apply the environmentally hazardous chlorinated para $n oils in order to insure a uccessful production.In connection with development of alternative lubricants the present paper describes a new lubricant test for punching.
