Abstract
Most metal forming processes use lubricants based on mineral
oils as an intermediate medium to reduce friction and wear. To
avoid the well-known drawbacks of oil lubrication, a novel and
environment friendly lubrication system for deep-drawing
processes was demonstrated at the University of Stuttgart.
Liquid carbon dioxide and gaseous nitrogen are being used as
volatile lubrication during the deep-drawing process, locally
injected at high pressure through laser-drilled microholes. This
new tribological system provides a significantly enlarged
working range and at least 15\% larger drawing depths compared
to conventional oil lubrication.
