The main function of the ball screw is to support the linear motion, which makes the linear motion more accurate and can still adhere to the linear motion at high speed. Its own guide rail request is also high. As long as the guide rail can provide an accurate way, it can ensure the efficiency of linear motion. The ball screw requests the guide rail in detail.

1、导向的精度请求；导轨支持运动做直线运动还是做带有圆度的运动，而影响到导向精度的是导轨的几何精度还有构造方式。当然了导轨的热变形也在一定水平上影响到了准确度，还有工作时分可能碰到的特殊状况，比方说是油膜的厚度。

1. Precision request of guidance; The guide rail supports linear motion or motion with roundness, and what affects the guiding accuracy is the geometric accuracy and construction mode of the guide rail. Of course, the thermal deformation of the guide rail also affects the accuracy to a certain extent, as well as the special conditions that may be encountered during work, such as the thickness of the oil film.

2、耐磨；重复的直线运动，请求导轨的耐磨性要较高，否直线运动的时间一长，导轨自身的准确度就曾经降低了，那么滚珠丝杆的直线运动的稳定性也就遭到了影响。

2. Wear resistance; The repeated linear motion requires the wear resistance of the guide rail to be higher. If the linear motion takes a long time, the accuracy of the guide rail itself will be reduced, and the stability of the linear motion of the ball screw will be affected.

3、避免疲倦点的突变；重复的直线运动，导轨上面就会呈现疲倦点，而这个疲倦点就会呈现凹坑的状况，所以在控制滚动导轨的时分一定要思索到大负荷状况和接受力度能否平均的状况。避免疲倦点呈现突变，就可以确保导轨的准确性。

3. Avoid mutation of fatigue point; Repeated linear movement will present a fatigue point on the guide rail, and this fatigue point will present a pit. Therefore, when controlling the rolling guide rail, we must consider whether the heavy load condition and acceptance force can be average. To avoid sudden changes in fatigue points, the accuracy of the guide rail can be ensured.

滚珠丝杆对导轨的请求是比拟高的，就怕重复的直线运动招致导轨上面呈现疲倦点，招致疲倦点呈现坑洼的状况下使得直线运动不能准确。因而在选购的时分，导轨的耐磨性和接受力度问题一定要被思索进去。

The request of the ball screw for the guide rail is relatively high. It is afraid that the repeated linear motion will lead to fatigue points on the guide rail, and the linear motion can not be accurate when the fatigue points are pitted. Therefore, at the time of purchase, the wear resistance and acceptance of the guide rail must be considered.
