Today, manufacturing engineering for no lubricant or dry metal forming processes is desired for the global environmental safeguarding. As one of the promising approaches, the lubricant pre-coated steel sheet has been developed and applied to the parts of household electrical machinery. The lubricant pre-coated steel sheet is the sheet coated beforehand by the resin layer with PTFE wax particles involved and can be formed by press without additional lubricant. The purpose of this research is to investigate the friction behavior of the lubricant pre-coated steel sheet in the ironing process. The friction coefficient in the ironing process was measured directly by using a strip ironing type tribometer and a rolling type tribometer. The friction behavior and surface damage were investigated by changing the reduction in thickness, ironing velocity. Experimental results showed that a thicker lubrication layer gives smaller friction coefficient.
