The high speed drilling shaft and pin cylinder system work at the same referenceaxis to ensure high work precision and convent operation.
高速精密钻孔主轴和钉销气缸系同基准轴线上工作，能保证工作精度高，操作方便。

Thus, an image displayed on the image display region is enlarged and projected on a position that is eccentric with reference to the referenceaxis.
因 此，在图像显示区域上显示的图像被放大并被投射到相对于参考轴偏心的位 置上。

An axis external circle simulates a reference shaft line to realize the principle of the measurement of the plane to the symmetrical characteristic of the referenceaxis.
