Stay High precision parts customization In ， Such as Copper products processing ， After lubrication on the guide surface ， Reduce friction coefficient ， Reduce wear ， And it can prevent the rail surface from rusting 。 Machining Factory ， The lubricants commonly used for guide rail are lubricating oil and grease ， The former is used for sliding guide ， The rolling guide is used for both 。

　　（1） Lubrication method ： The simplest way to lubricate the guide rail is to process it manually and regularly or to supply oil with an oil cup 。 This method is simple 、 Low cost ， But not reliable. ， Generally used to adjust the auxiliary guide rail and the movement speed is low 、 Infrequent rolling guide 。

　　（2） Requirements for lubricating oil ： Stay When the working temperature changes ， The viscosity change of lubricating oil should be small ， Good lubrication performance and sufficient oil film rigidity ， Oil In As few impurities as possible and do not corrode the parts 。 Commonly used oil for loss system includes L-AN10、L-AN15、L-AN32、L-AN42、L-AN68， Precision machine guide oil L-HG68， Turbine oil L-TSA32、L-TS46 Etc. 。

　　 Machining plant ， To prevent chips 、 Scattering of abrasive particles or cutting fluid Stay Wear on guide surface 、 Scratch and rust ， Reliable protective device shall be provided on the guide rail surface 。 Commonly used scraper type 、 Roller shutter and laminated protective covers ， Mostly used on long rails 。 Stay Operation process of machine tool In The protective cover should be protected from damage ， For the laminated protective cover, always clean the moving joint with the brush dipped in the oil ， In order to avoid the phenomenon of collision with the shell 。
