Ensure that the lathe dog is secured to the machined flat on the end of the mandrel and not on the smooth surface of the mandrel taper (Figure 7-44).

确保车床轧头牢牢地固定在心轴端的机械平面上，而不是锚定在锥形心轴的平滑面上(图7 - 44)。

At present, the ring rolling technology roll one ring in one process, and the technology can't deal with stress focus on the sharp taper Angle of mandrel roller.

目前锥形套圈辗扩技术只能一次成形一件，而且由于锥形套圈锥角使得芯辊应力集中严重。
