The aim of this study is to get a better understanding of Micro Flat-Wire Roll Forming Technology. There are three methods for Mirco flat-wire forming, i.e., drawing, extrusion, and rolling. Without replacing the equipment, rolling method only demands to adjust the relative roll gap between the pressure and the wire deformation that it can produce different specifications of mirco flat-wire. The rolling equipment was introduced and can be divided into three parts, the mechanism section, the control part and the wire-locating device. Furthermore, the rolling process parameters were summarized as well. The effect of rolling amount and rolling speed on the wire surface quality was also discussed.
