Ball screw due to high movement efficiency, small heat, it can achieve high-speed feed (motion).

滚珠丝杠由于运动效率高、发热小，故可实现高速进给(运动)。

Ball screw using ball movement, so the starting torque is very small, does not appear sliding movement crawling phenomenon, so can ensure accurate micro feed.

滚珠丝杠利用的是滚珠运动，因此启动力矩极小，不会出现滑动运动那样的爬行现象，故而能保证实现精确的微进给。

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

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。
