Lubrication of guide rails in mechanical processing plants

In high-precision parts customization, such as copper processing, the guide surface is lubricated to reduce the coefficient of friction, reduce wear, and prevent rust on the guide surface. The commonly used lubricants for the guide rail are lubricating oil and grease, the former is used for the sliding guide rail, and the rolling guide rail is used for both. Inner Mongolia machining.

(1) Lubrication method: The relatively simple lubrication method of the guide rail is manual regular processing or oil cup supply. This method is simple, low cost, but not reliable, and is generally used to adjust the auxiliary guide rail and the rolling guide rail with low movement speed and infrequent work.

(2) Requirements for lubricating oil: When the working temperature changes, the viscosity of lubricating oil should be small, there should be good lubrication performance and enough oil film stiffness, and the impurities in the oil should be as little as possible and not erode the parts.

Commonly used loss system oils are L-AN10, L-AN15, L-AN32, L-AN42, L-AN68, precision machine tool guide oil L-HG68, turbine oil L-TSA32, L-TS46 and so on.

Mechanical processing plant, in order to prevent chips, abrasive particles or cutting fluid scattered on the guideway surface caused by wear, abrasion and rust, the guideway surface should have a reliable protection device. The commonly used scraper, rolling shutter and laminated protective covers are mostly used on long guide rails.

In the process of using the machine tool should prevent damage to the protective cover, the laminated protective cover should often use a brush dipped in oil to clean the moving joint to avoid the phenomenon of touching the shell.
