The spindle system for high-speed milling processing is the core component of the high-speed milling machine. The lubrication method and cooling system selected for the electric spindle at high speed will have an important impact on the service life of the high-speed electric spindle and the accuracy of milling processing.
The lubrication system of the electric spindle of high-speed milling machines generally uses grease lubrication and oil-gas lubrication. Grease lubrication is generally used on electric spindles with simple structures. It is easy to use, but the temperature rise of the spindle is high and the working life is short. Due to its simple structure and relatively low purchase cost, it is also used on low-end high-speed milling machines.
Oil-air lubrication of high-speed milling machine electric spindle uses compressed air to continuously and accurately supply a small amount of lubricating oil to each set of spindle bearings. Tiny oil droplets are formed between the rolling elements and the inner and outer raceways. Elastic dynamic pressure oil film, and compressed air can take away part of the heat generated by the bearing operation. At the same time, the compressed air forms a certain positive pressure in the spindle bearing, which can effectively prevent impurities and the like from entering the bearing. Dopse
