Effect of different base oils on tribological performance of different metal sheets for stamping
Several types of metal sheets were tested in model tribological device, simulating stamping process, by using different types of base lubricants. In addition the tests without lubricant were also performed. The results show that some lubricants can even deteriorate tribological performance of stamping contact, by increasing the coefficient of friction between metal sheet and tool. What is more, the chemical composition of base metal working fluid and well as its viscosity play an important role in tribological performance that is critically defined by amount of transfer film from metal sheet to tool.
