Spindle oil is a special lubricant for spindle bearings of precision machine tools and similar equipment. It plays an important role in ensuring the working accuracy and performance of the spindle and prolonging its service life. We call it bearing oil.
The machining precision of precision cutting machine tools is related to the accuracy of the guide rail assembly and the tool level and is largely determined by the running accuracy of the spindle. The clearance between the spindle and the main bearing is very small, generally 0.002 to 0.060 mm, and the rotational speed is between 1000 and 300 r/min. The bearings for the spindle are all plain bearings. Some of the oil supply methods are cyclic, and some are oil bath type. Used in such a sophisticated machine tool, it is conceivable how high the requirements of the machine tool for the spindle oil performance are!
