hiwin直線導軌的作用是使運動部件能夠沿著一定的軌跡運動，起導向的作用，并承受運動部件以及工件的重量和切削力。一般的話hiwin直線導軌應該滿足精度高、壽命長、剛度和承載能力大、摩擦阻力小以及運動平穩、結構簡單、便于加工這方面的要求的。

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.

導軌體導靜壓hiwin直線導軌是滑動hiwin直線導軌的一種，是hiwin直線導軌以上所說特點設計開發的一種廣泛應用在高精密數控設備上的hiwin導軌的類型，這種hiwin導軌優點更為突出：

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直線導軌副間為純液體的摩擦，摩擦的系數是出彩小的，所以大大的減小了驅動功率，同時hiwin導軌磨損很小，使用壽命較長。

(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響比較小，不容易產生爬行，滑臺低俗性能好。

(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）油膜的承載能力大的話，剛度也高，吸振性能較好，hiwin直線導軌的運行也是比較平。

(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）油膜具有誤差均化的作用，可以提高hiwin導軌的運動精度。

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

靜壓hiwin導軌唯一的一個劣勢就是需要配合一套具有良好過濾效果的液壓裝置，既占有的空間，又相對的增加了成本。但是從機床性方面考慮，諸如設備的加工精度、加工范圍以及加工可靠性等諸多的因素，這點投入顯得微不足道。

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.

在運用到hiwin直線導軌的同時提高靜壓hiwin直線導軌運行精度， 會給我們的工作帶來方便。
