The automation accessory system has its own operation mode. Of course, the guide rail as a member of the automation accessories should also operate according to its own operation mode. Today, let's learn about the operation mode of the lower guide rail.

盡管導(dǎo)軌系統(tǒng)的形式是多種多樣的，但工作性質(zhì)都是相同的，機(jī)床工作部件在指定導(dǎo)軌系統(tǒng)上移動(dòng)，尤如火車沿著鐵軌在指定的方向上行駛。無論是機(jī)床導(dǎo)軌還是鐵路上的鐵軌，都是體現(xiàn)如下三種基本功能：

Although there are many forms of guide rail system, the working properties are the same. The working parts of machine tool move on the specified guide rail system, especially when the train runs along the rail in the specified direction. Both machine tool guide rail and railway rail reflect the following three basic functions:

（1）為承載體的運(yùn)動(dòng)導(dǎo)向

(1) Guide the movement of the bearing body

（2）為承載體提供光滑的運(yùn)動(dòng)表面

(2) Provide a smooth moving surface for the bearing body

（3）把火車的運(yùn)動(dòng)或機(jī)床的切削所產(chǎn)生的力傳到地基或床身上，減少由此產(chǎn)生的沖擊對乘客和被動(dòng)加工零件的影響。

(3) The force generated by the movement of the train or the cutting of the machine tool is transmitted to the foundation or bed to reduce the impact on passengers and passively machined parts.

沿導(dǎo)軌系統(tǒng)的運(yùn)動(dòng)，大多數(shù)為直線運(yùn)動(dòng)，也有少數(shù)為弧線運(yùn)動(dòng)。本文討論的是直線導(dǎo)軌系統(tǒng)。當(dāng)然，直線導(dǎo)軌的很多技術(shù)可以直接應(yīng)用弧形導(dǎo)軌。

Most of the motion along the guide rail system is linear motion, and a few are arc motion. This paper focuses on the linear guide rail system. Of course, many technologies of linear guide rail can be directly applied to arc guide rail.

導(dǎo)軌為什么被稱為“系統(tǒng)”呢？這是因?yàn)閷?dǎo)軌系統(tǒng)的工作包含著若干元件的同時(shí)工作，基本的元件為一個(gè)運(yùn)動(dòng)元件和一個(gè)固定元件。運(yùn)動(dòng)元件的形式有多種多樣，以后將予以詳細(xì)介紹，固定元件一般為道軌式，它是導(dǎo)軌精度的保證，如果導(dǎo)軌彎曲變形，運(yùn)動(dòng)元件或滑動(dòng)元件便失去的導(dǎo)向。

Why is the guide rail called "system"? This is because the work of the guide rail system includes the simultaneous work of several elements, and the basic elements are a moving element and a fixed element. There are many forms of moving elements, which will be introduced in detail later. The fixed elements are generally track type, which is the guarantee of guide rail accuracy. If the guide rail is bent and deformed, the moving elements or sliding elements will lose their guidance.

了解了導(dǎo)軌絲杠的運(yùn)轉(zhuǎn)方式以后，我們在實(shí)際使用過程中要時(shí)刻注意它的運(yùn)轉(zhuǎn)方式的一些部位的壽命和運(yùn)轉(zhuǎn)情況。

After knowing the operation mode of the guide screw, we should always pay attention to the service life and operation of some parts of its operation mode in the actual use process.
