摘要： A ball rolling groove 1c is defined in an inner peripheral surface of A ball screwed nut 1 by a rolling process, not by a grinding process so that a ball screwed nut having small diameters or large leads can be manufactured. The surface of the ball rolling groove 1c is finished to be sharp without concave and convex by a plastic working by the rolling process, so that the surface is less rough. By rolling the surface by the rolling process excellent in durability, the precision of R shape of the ball rolling groove 1c can be made excellent.
摘要翻译： 甲滚道槽1c处于滚珠丝杠螺母1的内周面通过滚轧过程中定义，而不是由一个研磨过程所以也可以制造具有小的或大直径导线的滚珠丝杠螺母。 所述滚道槽1c的表面加工成是没有凹凸由塑料通过轧制加工工作尖锐，所以DASS模具表面是粗糙的较少。 通过轧制过程具有优异的耐久性滚动表面，所述滚道槽1c的R形的精度可制成优异。
