检测工具頂尖的尖部颤抖计算精度时，不得不在頂尖顶紧类件的程序下参与打表。
Inspecting the run out accuracy of the center tip must be under the
status of holding the workbar tightly.
另有同的规格轻负载（S型，无螺母），可增强细长轴类零件易出现变形话题
There is S model of light duty type, 🌱same spec, which can improve the issue of deformation of processing slender workpiece
