Reasons for the deterioration of machine tool lubricants, and how to prevent it
The functions of lubricating oil can be summarized into five points: lubrication, sealing, cleaning, corrosion prevention, and cooling. The ability of lubricating oil to provide lubrication depends on the molecular structure of its base oil and the properties of the additives. Therefore, higher operating temperatures, metal catalysis, oxygen ingress, moisture intrusion, and continuous shear can cause the base oil to oxidize and the additives to become ineffective, resulting in a loss of lubrication and sealing capabilities ； Furthermore, as impurities are generated and accumulate, the lubricating oil’s ability to dissolve foreign substances is limited, which in turn reduces its cleaning and cooling functions
