Linear guide rail, also known as line rail, slide rail, linear guide rail, linear slide rail, is used in high-precision or high-speed linear reciprocating motion occasions, and can bear a certain torque, can achieve high-precision linear motion under high load. In Taiwan, linear guideway is generally called linear guideway. Linear guide can be divided into: roller linear guide rail, cylindrical linear guide rail, ball linear guide rail, three kinds are used to support and guide the moving parts to do reciprocating linear motion according to the given direction. According to the nature of friction, linear motion guide can be divided into sliding friction guide, rolling friction guide, elastic friction guide, fluid friction guide and so on.

直線導(dǎo)軌運(yùn)動(dòng)的作用是用來支撐和引導(dǎo)運(yùn)動(dòng)部件，按給定的方向做往復(fù)直線運(yùn)動(dòng)。依按摩擦性質(zhì)而定，直線運(yùn)動(dòng)導(dǎo)軌可以分為滑動(dòng)摩擦導(dǎo)軌、滾動(dòng)摩擦導(dǎo)軌、彈性摩擦導(dǎo)軌、流體摩擦導(dǎo)軌等種類。

The function of linear guide motion is to support and guide the moving parts to do reciprocating linear motion according to the given direction. According to the nature of friction, linear motion guide can be divided into sliding friction guide, rolling friction guide, elastic friction guide, fluid friction guide and so on.

直線軸承主要用在自動(dòng)化機(jī)械上比較多,像德國進(jìn)口的機(jī)床,折彎機(jī),激光焊接機(jī)等等,當(dāng)然直線軸承和直線軸是配套用的。像直線導(dǎo)軌主要是用在精度要求比較高的機(jī)械結(jié)構(gòu)上,直線導(dǎo)軌的移動(dòng)元件和固定元件之間不用中間介質(zhì)，而用滾動(dòng)鋼球。

Linear bearing is mainly used in automatic machinery, such as machine tools imported from Germany, bending machine, laser welding machine, etc., of course, linear bearing and linear shaft are used together. For example, linear guideway is mainly used in the mechanical structure with high precision requirements. There is no intermediate medium between the moving element and the fixed element of the linear guide, but rolling steel ball is used.

導(dǎo)軌、直線軸作為設(shè)備的核心部件之一，它的功用是起導(dǎo)向和支承作用。為了保證機(jī)器有較高的加工精度，要求其導(dǎo)軌、直線具有較高的導(dǎo)向精度和良好的運(yùn)動(dòng)平穩(wěn)性。

As one of the core components of the equipment, guide rail and linear shaft are used to guide and support. In order to ensure the high machining accuracy of the machine, the guide rail and straight line are required to have high guiding accuracy and good motion stability.

設(shè)備在運(yùn)行過程中，由于被加工件在加工中會(huì)產(chǎn)生大量的腐蝕性粉塵和煙霧，基這些煙霧和粉塵長期大量沉積于導(dǎo)軌、直線軸表面，對設(shè)備的加工精度有很大影響，并且會(huì)在導(dǎo)軌直線軸表面形成蝕點(diǎn)，縮短設(shè)備使用壽命。為了讓機(jī)器正常穩(wěn)定工作，確保產(chǎn)品的加工質(zhì)量，要認(rèn)真做好導(dǎo)軌、直線軸的日常維護(hù)。

During the operation of the equipment, a large amount of corrosive dust and smoke will be produced during the processing of the processed parts. Based on these smoke and dust, a large number of them are deposited on the surface of the guide rail and linear shaft for a long time, which has a great impact on the processing accuracy of the equipment, and will form corrosion spots on the surface of the linear axis of the guide rail, thus shortening the service life of the equipment. In order to ensure the normal and stable operation of the machine and ensure the processing quality of the products, it is necessary to do a good job in the daily maintenance of the guide rail and linear shaft.
