摘要： A method forms ball recirculation and rolling grooves at an inner circumferential surface of a nut for ball screw use in a state free of deviation in axial, circumferential, and radial nut directions. A flange end face is formed with a concave part, then an inner circumferential surface of a blank and an end face and outer circumferential surface of the flange are continuously ground. Due to this, the coaxiality of the blank inner circumferential surface and the flange outer circumferential surface, and the perpendicularity of the flange end face to the blank inner circumferential surface, are made smaller. The blank is plastically worked to form the ball recirculation groove and is cut to form the ball rolling groove while using the concave part as a phase reference, the end face as an axial direction reference, and the outer circumferential surface as a radial direction reference.
摘要翻译：一种方法在用于滚珠丝杠使用的螺母的内圆周表面上形成滚珠再循环和滚动槽，该轴向，圆周和径向螺母方向上没有偏差。凸缘端面形成有凹部，然后坯料的内周面和凸缘的端面和外周面连续接地。由此，使坯件内周面和凸缘外周面的同轴度以及凸缘端面与坯料内周面的垂直度变小。在将凹部作为相位基准，将端面作为轴向参考，将外周面作为径向基准的情况下，对坯料进行塑性加工以形成球再循环槽并切割以形成滚珠滚动槽。

摘要： A method forms a concave constituting a ball return passage directly on an inner circumferential surface of a nut blank by plastic working without damaging a die. Letter S shaped concaves are formed on an inner circumferential surface of a nut blank, by pressing by use of a die having a blank holder, a cam driver, cam sliders, and a cylindrical member. The cam driver has inclined surfaces having the same angle of inclination as the cam sliders. The cam sliders have letter S shaped convexes corresponding to the letter S shaped concaves, and are held by through holes, respectively. When the cam driver is pressed from the top thereof, the cam sliders move outwardly in the radial direction, respectively, and the letter S shaped convexes push the inner circumferential surface of the nut blank for plastic deformation.
