What kind of lubricating oil do CNC milling machines usually use?

The type of oil used for NC milling machine depends on the lubrication point. For CNC machine tools, the guide rail and hydraulic system need lubricating oil, such as guide rail oil. Some sliding parts require grease. Generally speaking, there are detailed descriptions of lubrication points, oil products and even oil change cycle in the manual of NC machine tools.

For the lubrication of products (workpieces) and cutting tools processed by the machine tool, cooling and lubrication are required during cutting, turning and other processes to ensure the normal operation of the machine tool. At this time, cutting oil is required. Therefore, anti-wear hydraulic oil and cutting oil are essential oils for CNC machine tools. CNC machine tools have high speed, high pressure and very high requirements for oil cleanliness, so the flash point, pour point, viscosity index, cleanliness and other indicators of anti-wear hydraulic oil are demanding. If anti-wear hydraulic oil with flash point 120, pour point-20, viscosity index 220 and cleanliness level 8 is used, it is undoubtedly a better protection for CNC machine tools and prolonging the service life of CNC machine tools is the guarantee.

According to the needs of lubricants and the operating environment of mechanical equipment, the selection of lubricants is more scientific. In addition, in order to promote the long-term operation of chemical machinery and equipment, staff need to strengthen lubricant management and store them by classification through scientific methods, so as to effectively avoid the wrong use of lubricants, so as to play an important role.
