檢測(cè)頂尖的尖部跳動(dòng)精度時(shí)，必須在頂尖頂緊工件的狀態(tài)下進(jìn)行打表。

Inspecting the run out accuracy of the center tip must be under the status of holding the workbar tightly.

另有同規(guī)格輕負(fù)荷（S型，無(wú)螺帽），可改善細(xì)長(zhǎng)工件易變形問(wèn)題

There is S model of light duty type, same spec, which can improve the issue of deformation of processing slender workpiece
