必须将心轴锚定在中心点和驱动板之间的位置,并且必须使用车床轧头。
The mandrel must be mounted between centers and a drive plate and lathe dog must be used.
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)。
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).
