Maintenance of spindle machine tools and equipment. Electric spindle is one of the core parts of machine tool equipment. The correct use and maintenance of the machine tool is the precondition to ensure the machining accuracy and service life of the machine tool.



First of all, it should be emphasized not to clean the spindle with compressed air, so as to avoid bringing dust into the gap of the spindle, and then damage the spindle bearing. When cleaning the area around the spindle, although the spindle stops, the machine tool should be electrified, and the spindle bearing should be kept in the air curtain protection state. Secondly, in the process of using motorized spindle, attention should be paid to cutting fluid should be hit on the cutting tool, do not hit the spindle end.



Tools mounted on the spindle. The handle part must be cleaned regularly with a clean soft cloth to avoid bringing dust into the spindle cone hole. Even when the machine tool is not in use, a tool handle should be retained on the spindle to protect the taper hole of the spindle.



New or unused motorized spindle for more than a month must be rotated at a low speed at the beginning of work, and it is better to preheat the spindle for air operation. The taper hole is not loaded with the tool handle. The spindle is forbidden to run.



In order to maintain the high precision of the motorized spindle for a long time and obtain the best processing effect, when the motorized spindle runs at high speed, only the precise dynamic balancing tool can be used. When cutting with high precision, it is better to preheat the spindle for 30 minutes to achieve thermal stability.



Generally speaking, different motorized spindles have different specifications and sizes for tool selection. The machine tool spindle uses a tool with a minimum diameter of 1 mm and a maximum of 32 mm, and the length of the tool should not exceed 100 mm. On the premise of optimizing cutting conditions, the above parameters can be adjusted appropriately, but the spindle should not be overloaded under any circumstances.
