If the temperature of the spindle bearing of the CNC lathe is too high, the temperature of the spindle will also increase, which will cause the bearing to burn out. So what are the reasons for the increase in the bearing temperature? Xiaobian will tell you one by one! The high temperature of the CNC lathe spindle leads to overheating. The reason can be roughly summarized as the friction between the CNC lathe spindle bearings causes the temperature to be too high. To avoid this factor, attention should be paid to adjusting the gap between the CNC lathe spindle bearings and applying appropriate lubricating oil regularly. CNC lathes generally include spindles and CNC lathe spindle bearings and sliding bearings and other components. When the rotational speed is relatively high, the temperature will rise rapidly, which may lead to bearing deformation in the long run and also lead to insufficient precision of CNC lathes, or direct burnout. bearing. 37 years of professional experience in the production of CNC lathe spindle bearings, teach you how to avoid the above situation: 1. Reduce the inner and outer diameters of the bearing rolling elements. It can reduce the friction between the bearing and the main shaft, thereby reducing the temperature of the bearing during operation; 2. The lubrication method should be reasonable. According to different lathes and environments, choose appropriate lubricating oil and lubricate regularly; 3. Choose good bearing raw materials. The raw materials for the spindle bearings of CNC lathes are all purchased by our company, and the steel is preferably Xingcheng Special Steel and Daye Special Steel. The steel balls are made by the two best steel ball manufacturers in China at present, Universal and Dong’e, and the cages are made of tin balls that are second to none in China. your cost.
