hiwin直線導(dǎo)軌的作用是使運(yùn)動(dòng)部件能夠沿著一定的軌跡運(yùn)動(dòng)，起導(dǎo)向的作用，并承受運(yùn)動(dòng)部件以及工件的重量和切削力。一般的話hiwin直線導(dǎo)軌應(yīng)該滿足精度高、壽命長(zhǎng)、剛度和承載能力大、摩擦阻力小以及運(yùn)動(dòng)平穩(wěn)、結(jié)構(gòu)簡(jiǎn)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(dǎo)軌體導(dǎo)靜壓hiwin直線導(dǎo)軌是滑動(dòng)hiwin直線導(dǎo)軌的一種，是hiwin直線導(dǎo)軌以上所說(shuō)特點(diǎn)設(shè)計(jì)開(kāi)發(fā)的一種廣泛應(yīng)用在高精密數(shù)控設(shè)備上的hiwin導(dǎo)軌的類型，這種hiwin導(dǎo)軌優(yōu)點(diǎn)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(dǎo)軌副間為純液體的摩擦，摩擦的系數(shù)是極小的，所以大大的減小了驅(qū)動(dòng)功率，同時(shí)hiwin導(dǎo)軌磨損很小，使用壽命較長(zhǎng)。

(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(chǎn)生爬行，滑臺(tái)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(dǎo)軌的運(yùn)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h(yuǎn)iwin導(dǎo)軌的運(yùn)動(dòng)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(dǎo)軌的一個(gè)劣勢(shì)就是需要配合一套具有良好過(guò)濾效果的液壓裝置，既占有的空間，又相對(duì)的增加了成本。但是從機(jī)床性方面考慮，諸如設(shè)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(diǎn)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(yùn)用到hiwin直線導(dǎo)軌的同時(shí)提高靜壓hiwin直線導(dǎo)軌運(yùn)行精度， 會(huì)給我們的工作帶來(lái)方便。

Improving the operational accuracy of static pressure hiwin linear guides while applying them will bring convenience to our work.
