Recently, highly straight wire has been widely used in high-efficiency electronic and medical devices. A rotational blade straightener is particularly effective for straightening coiled wires because the straightener can bend wires along both the longitudinal and circumferential directions. However, it is difficult to straighten fine wires without the need for operators to adjust the straightener, and there is little research on wire straightening. We used fine stainless-steel(AISI 304) wires as experimental specimens. Currently, two blades are used to bend and counterbend a wire. Here, we describe two methods of wire straightening using a rotational blade straightener, and compare the new method with the current method. Intentional twisting is newly applied to wire straightening. We found that the twisting method is easier and more effective than the current bending method. Furthermore, the final straightness is greatly improved by tension annealing after rotational blade straightening.
