hiwin直线导轨的作用是使运动部件能够沿着一定的轨迹运动，起导向的作用，并承受运动部件以及工件的重量和切削力。一般的话hiwin直线导轨应该满足精度高、寿命长、刚度和承载能力大、摩擦阻力小以及运动平稳、结构简单、便于加工这方面的要求的。

The function of hiwin linear guide is to enable moving parts to move along a certain trajectory, play a guiding role, and bear the weight and cutting force of moving parts and workpieces. In general, hiwin linear guides should meet the requirements of high precision, long service life, high stiffness and load-bearing capacity, low friction resistance, smooth motion, simple structure, and easy processing.

导轨体导静压hiwin直线导轨是滑动hiwin直线导轨的一种，是hiwin直线导轨以上所说特点设计开发的一种广泛应用在高精密数控设备上的hiwin导轨的类型，这种hiwin导轨优点更为突出：

The guide body static pressure hiwin linear guide is a type of sliding hiwin linear guide, which is designed and developed based on the characteristics mentioned above and is widely used in high-precision CNC equipment. The advantages of this type of hiwin guide are more prominent:

（1）hiwin直线导轨副间为纯液体的摩擦，摩擦的系数是极小的，所以大大的减小了驱动功率，同时hiwin导轨磨损很小，使用寿命较长。

(1) The friction between the hiwin linear guide rail pairs is pure liquid, and the coefficient of friction is extremely small, which greatly reduces the driving power. At the same time, the wear of the hiwin guide rail is very small, and its service life is long.

（2）油膜的厚度受到的速度影响比较小，不容易产生爬行，滑台低俗性能好。

(2) The thickness of the oil film is less affected by the speed, making it less prone to crawling. The sliding table has good performance due to its low quality.

（3）油膜的承载能力大的话，刚度也高，吸振性能较好，hiwin直线导轨的运行也是比较平。

(3) If the load-bearing capacity of the oil film is large, the stiffness is also high, the vibration absorption performance is good, and the operation of the hiwin linear guide rail is also relatively smooth.

（4）油膜具有误差均化的作用，可以提高hiwin导轨的运动精度。

(4) The oil film has the function of error equalization, which can improve the motion accuracy of hiwin guide rails.

静压hiwin导轨的一个劣势就是需要配合一套具有良好过滤效果的液压装置，既占有的空间，又相对的增加了成本。但是从机床性方面考虑，诸如设备的加工精度、加工范围以及加工可靠性等诸多的因素，这点投入显得微不足道。

The only disadvantage of the static pressure hiwin guide rail is the need to cooperate with a hydraulic device with good filtering effect, which not only occupies space but also relatively increases cost. However, from the perspective of machine tool performance, many factors such as equipment processing accuracy, processing range, and processing reliability make this investment seem insignificant.

在运用到hiwin直线导轨的同时提高静压hiwin直线导轨运行精度， 会给我们的工作带来方便。
