如前所述，当依靠驱动大拖板的丝杆切削螺纹时轴向进给是自动产生的。

As previously mentioned, the axial feed is automatically generated when cutting a thread by means of the lead screw, which drives the carriage.

进给传动：三向进给均采用交流伺服电机驱动精密滚珠丝杆，专用丝杆轴承支承，提高了机床的进给运动刚性和精度。

Feed transmission: using AC servo motor to drive the precise ball screw sets that supported by special ball screw bearing, which improves the rigidity and precision of feed movement.

导轮架进给导轨采用燕尾形滚针导轨，进给用差动丝杆；

The regulating wheel feed slide is supported on dovetail needle roller guideway and a differential leadscrew is used for performing feed motion.
