In the daily use of transmission parts, for the fluid lubrication of sliding guide rail surface, the movement accuracy error caused by the floating of oil film is inevitable. In most cases, fluid lubrication is limited to the boundary area, and direct friction caused by metal contact is inevitable, in which a large amount of energy is wasted by friction loss. On the contrary, because of the low friction energy consumption and the corresponding reduction of friction loss on the rolling surface, the linear guide rail system can be in a high-precision state for a long time. At the same time, due to the small amount of lubricating oil, grease lubrication is enough in most cases, which makes it very easy to design and maintain the lubrication system of machine tools.
There is a slight or negative gap between the slider of the rolling linear guide rail and the guide rail, so the overall rigidity and movement accuracy of the guide rail can be greatly improved. The E2 self-lubricating module product with innovative design of linear guide rail combines the concept of removable type, which makes the linear guide rail extend its maintenance cycle. E2 self-lubricating module is characterized by cost saving, cleanness and environmental protection, flexible installation, convenient disassembly and assembly and easy maintenance. The transparent oil tank design can check the oil quantity at any time, and the corresponding lubricating oil can be selected. It can be used in special environment such as dust, bad weather and water environment.
In order to improve the motion accuracy and accuracy maintenance, linear guideway requires enough negative numbers, which are two contradictory aspects. When the working time is too long, the steel balls begin to wear, and the preload acting on the steel balls begins to weaken, which leads to the decrease of the motion accuracy of the working parts of the machine tool. If you want to keep the initial accuracy of the linear guide, you must replace the guide bracket or even the guide. If the guide rail system has been preloaded. The accuracy of the system has been lost, and the only way is to replace the linear slider and guide rail.
