Lubricant oil is always used to improve or enhance the deep drawing limit and prevent the damage on the surface of cylindrical parts. Therefore, the oil on cylindrical parts must be cleaned by cleaning agent after deep drawing. Not only the cost of lubricant oil and the cleaning is needed, but also the lubricant oil and cleaner affect the environment of the earth. The authors have created the new deep drawing method to prevent the global environment. High pressure jet water is adopted on the new deep drawing instead of the lubricant oil. The water viscosity is low and the water itself is not suitable for lubricant. But the high pressure water jet is compulsorily supplied to the gap between the die and sheet metal, and strong lubricant membrane is produced in the gap. The effects of the deep drawing conditions are experimentally examined on the new deep drawing using high pressure jet water. Therefore the capability and character of the drawing are made clear in this study.
