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?

　　，直线导轨系统里面离不开密封件的运用，由于它有不少的缝隙比拟容易让灰尘和杂质钻空子，所以要想让整个系统内部到达一个密封的状态就必需要用密封垫片将这些缝隙给堵上。但是关于密封垫片的运用是有一些考究的，它不是普通的资料就能够，相反，用于制造直线导轨密封垫片的资料必需是的橡胶资料，然后制造成清洁环。橡胶垫片较大的益处就在于它具有十分强的韧性，弹性系数十分高，固然它的制造本钱比普通的塑料垫片高了很多，但是它作为垫片运用的时分能够不留半点缝隙。
                             

　　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，防尘罩的运用对防尘也有很好的效果，如今运用的防尘罩有特地针对恶劣环境和普通的工作环境两种。在恶劣环境下运用的防尘罩柔软性是十分好的，它能够自在的伸缩，这样就能应对不同的机床构造。还有一种是防尘器，它主要是避免灰尘接近直线导轨。

　　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.

　　较后，假如需求对直线导轨的滚珠丝杆提供防尘维护的话，还能够运用大型的伸缩防尘罩。

　　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.
