Depending on the Draw Bead Simulator (DBS), the influence of six lubricants to the frictional coefficient of five different kinds of auto\|sheets when they were pulled through the draw bead was analyzed. The result showed that the coefficient of friction decreased with the increase of the viscosity of the lubricants. The degree of the COF of different sheets varies with the different lubricant and the Electro\|galvanizing phosphate sheet has the lowest COF of the five auto-sheets.
