High-speed motorized spindle is the core component of high-speed machine tools. Correct use and maintenance of motorized spindle has an important impact on improving the machining accuracy and prolonging the service life of high-speed machine tools. The following points can improve the use and maintenance effect of motorized spindle.



Don't clean the motorized spindle with compressed air, avoid bringing dust into the gap of the spindle, and then damage the spindle bearing.



(2) When cleaning the area around the motorized spindle, although the spindle stops, the machine tool should be electrified and the spindle bearing should be protected by air curtain.



(3) During the use of motorized spindle, attention should be paid to the cutting fluid should be hit on the cutting tool, not on the spindle end.



(4) The tool holder of the tool mounted on the motorized spindle must be cleaned regularly with clean soft cloth to avoid dust being brought into the cone hole of the spindle. Even when not in use, a tool holder should be retained on the spindle to protect the cone hole of the spindle.



_New or unused motorized spindle for more than a month, at the beginning of work, we must ensure low-speed rotation, preheating and air operation of the spindle.



In order to ensure the high accuracy of the motorized spindle, the dynamic balance reaching standard tool can only be used in high-speed operation, and the motorized spindle can be preheated for 30 minutes during high-precision cutting to achieve thermal stability.
