What are the reasons for the overheating of CNC lathe spindle bearings? -

Excessive temperature of the spindle bearing of CNC lathe will also cause the temperature of the spindle to rise, which will cause the bearing to be burned out. So what are the reasons for the temperature rise of the bearing? Let me tell you one by one! The temperature of the CNC lathe spindle is too high to cause overheating. The reason can be roughly summarized as the friction between the spindle bearings of the CNC lathe and the temperature is too high. To avoid this factor, attention should be paid to adjusting the gap between the spindle bearings of the CNC lathe and applying suitable lubricating oil regularly. CNC lathes generally include the main shaft and CNC lathe spindle bearings and sliding bearings. When the speed is relatively high, the temperature will rise quickly. In the long run, it may cause deformation of the bearings and lead to insufficient precision of the CNC lathe, or direct burnout. bearings. 37 years of professional CNC lathe spindle bearing production experience, teach you how to avoid the above situation: 1. Reduce the inner and outer diameter of the bearing rolling body. 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 suitable lubricating oil and lubricate regularly; 3. Choose good bearing raw materials. The raw materials of CNC lathe spindle bearings are purchased by our company independently, and the steel materials are given priority to Xingcheng Special Steel and Daye Special Steel. The steel balls are made of the two best steel ball manufacturers in China, General Motors and Dong'a, and the cage is made of tin balls, which are second to none in China. The bearings have high speed and long life. your cost. Only when the torque is accurate can the rotation be stable!
