1、 穩(wěn)定的定位精確度

1. Stable positioning accuracy

熱膨脹會導(dǎo)致滾珠絲杠的精度減低，由于空心軸抑制了由于溫度升高而造成的熱脹，所以能夠是的滾珠絲杠的精度穩(wěn)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

還是通過降低熱膨脹的發(fā)生，將滾珠絲杠支撐軸和底座位移控制在zui小的范圍內(nèi)，同時空心軸的冷卻作用有效地阻隔了對其他部位的熱傳導(dǎo)，從而避免了工作臺因為熱而發(fā)生變形。

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、有效縮短預(yù)熱時間

3. Effectively shorten preheating time

空心軸冷卻作用可以降低溫度上升的幅度，從而縮短了設(shè)備的預(yù)熱時間。

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

4、有效維持滾珠絲杠的潤滑性能

4. Effectively maintain the lubrication performance of ball screws

因為避免了滾珠絲杠的發(fā)熱，減緩了潤滑油變質(zhì)的速度，可以更好保持潤滑油的有效性。

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.
