Cylindrical cup deep drawing technology is used in various manufacturing processes. For example, it is used in the automotive industry to manufacture auto parts. It is also used in the manufacture of household items. Lubricants are used in metal forming, especially deep drawing, to reduce friction between the tool and the workpiece. As a result, lubrication reduces forming energy and forming steps, increases the drawing ratio and tool life, while preventing galling, seizure and surface damages to the products. In this paper, the main purpose was to increase the deep drawing ratio and reduce the drawing force by angling the die and blank holder, and investigated the effect of lubrication on the deep drawing process. The force required and quality of deep-drawn cylindrical steel cups. Two different lubricants mineral and solid lubricant were used as well as two different die angles between the die and the blank holder (α = 0o and 15o). The results shows that The Limit drawing ratio increased from 1.75 to 2.175 without failure, The oil lubricant shows better enhancement of the drawing ratio and reduced the maximum drawing force
