Effect of Molecular Structure of Oil on the Film Thickness during Rolling

In recent years, metal working oil is required to have lower viscosity and higher lubricity than ever. Controlling oil film thickness is one of the most important in metal working. In this study, we investigated the effect of molecular structure and molecular weight distribution of oil on both lubri...
