Hole Center And Surface的意思|示意

When machining shaft parts, always machining center hole, and then to the center of the center hole for the processing of the outer surface.

如加工轴类工件时，总是先加工中心孔，再以中心孔为基准加工外圆表面。

The deformation hole and the protrusion are arranged in a manner that a line connecting the center of the deformation hole to the protrusion is substantially perpendicular to the side surface.

变形孔和突出部设置的方式使得变形孔的中心和突出部的连线基本上垂直于侧表面。
