Dust-proof is a key measure for linear guide to obtain good machining accuracy and adhere to its performance characteristics. Any dust and impurities are bad for components with high precision requirements, which can destroy the whole linear motion system and shorten service life. So, how to do a good job in the dust prevention of linear guide?

　　首先，直線導軌系統里面離不開密封件的運用，由于它有不少的縫隙比擬容易讓灰塵和雜質鉆空子，所以要想讓整個系統內部到達一個密封的狀態就必需要用密封墊片將這些縫隙給堵上。但是關于密封墊片的運用是有一些考究的，它不是普通的資料就能夠，相反，用于制造直線導軌密封墊片的資料必需是的橡膠資料，然后制造成清潔環。橡膠墊片較大的益處就在于它具有十分強的韌性，彈性系數十分高，固然它的制造本錢比普通的塑料墊片高了很多，但是它作為墊片運用的時分能夠不留半點縫隙。
                             

　　Firstly, the use of seals is indispensable to the linear guideway system. Because there are many gaps in the system, dust and impurities can easily be drilled into the voids. Therefore, in order to make the whole system reach a sealed state, it is necessary to use sealing gaskets to plug these gaps. However, the application of sealing gaskets is somewhat sophisticated, it is not common information can be used, on the contrary, the information used to manufacture linear guide gaskets must be professional rubber information, and then made into a cleaning ring. The greatest advantage of rubber gasket is that it has very strong toughness and high elasticity coefficient. Although its manufacturing cost is much higher than ordinary plastic gasket, it can be used as gasket without leaving half a gap.

　　其次，防塵罩的運用對防塵也有很好的效果，如今運用的防塵罩有特地針對惡劣環境和普通的工作環境兩種。在惡劣環境下運用的防塵罩柔軟性是十分好的，它能夠自在的伸縮，這樣就能應對不同的機床構造。還有一種是防塵器，它主要是避免灰塵接近直線導軌。

　　Secondly, the use of dust-proof cover has a good effect on dust-proof. Nowadays, the use of dust-proof cover is specially aimed at the harsh environment and the ordinary working environment. The dustproof cover used in harsh environment is very flexible, it can flexible freely, so that it can cope with different machine tool structures. There is also a professional dust preventer, which mainly avoids dust close to the linear guide.

　　較后，假如需求對直線導軌的滾珠絲桿提供防塵維護的話，還能夠運用大型的伸縮防塵罩。

　　Finally, if it is necessary to provide dust-proof maintenance for ball screw of linear guideway, large-scale retractable dust-proof cover can also be used.
