Background The linear motor sliding table module is widely applied to the fields of semiconductor equipment, precision machine tools and the like due to high precision and high response characteristics. When the sliding table moves at a high speed, sliding or rolling contact between the guide rail and the sliding block can generate dry friction, so that the surface of the metal material is scraped or worn. The lubricating grease can form a layer of oil film between contact surfaces, so that dry friction is converted into fluid friction or mixed friction, and friction loss is greatly reduced. The traditional slip table module adopts open guide rail design, through artifical periodic filling lubricating grease to slider oil filler point. However, with the increase of dust-free workshops and corrosive environments, the totally enclosed sliding table module becomes the mainstream.
