1、 稳定的定位精确度

1. Stable positioning accuracy

热膨胀会导致滚珠丝杠的精度减低，由于空心轴抑制了由于温度升高而造成的热胀，所以能够是的滚珠丝杠的精度稳定。

Thermal expansion can lead to a decrease in the accuracy of ball screws. Due to the hollow shaft suppressing thermal expansion caused by temperature rise, the accuracy of ball screws can be stabilized.

2、 有效防止各部分位移

2. Effectively prevent displacement of various parts

还是通过降低热膨胀的发生，将滚珠丝杠支撑轴和底座位移控制在zui小的范围内，同时空心轴的冷却作用有效地阻隔了对其他部位的热传导，从而避免了工作台因为热而发生变形。

By reducing the occurrence of thermal expansion, the displacement of the ball screw support shaft and base is controlled within the smallest range possible. At the same time, the cooling effect of the hollow shaft effectively blocks heat conduction to other parts, thereby avoiding deformation of the worktable due to heat.

3、有效缩短预热时间

3. Effectively shorten preheating time

空心轴冷却作用可以降低温度上升的幅度，从而缩短了设备的预热时间。

The cooling effect of the hollow shaft can reduce the amplitude of temperature rise, thereby shortening the preheating time of the equipment.

4、有效维持滚珠丝杠的润滑性能

4. Effectively maintain the lubrication performance of ball screws

因为避免了滚珠丝杠的发热，减缓了润滑油变质的速度，可以更好保持润滑油的有效性。

Because it avoids the heating of the ball screw and slows down the rate of lubricant deterioration, it can better maintain the effectiveness of the lubricant.
