CNC lathe bearing temperature detection is an important step to ensure the normal operation of the machine tool and extend its service life. The following are some suggestions and methods for CNC lathe bearing temperature detection:

1. Use an infrared thermometer: This is a commonly used non-contact temperature measurement tool that can quickly and accurately detect bearing temperature. When using the CNC lathe, you should maintain a certain distance and angle, and avoid being too close to other heat sources to avoid interfering with the measurement results.

2. Use temperature sensors: CNC lathe temperature sensors, such as thermocouples and thermistors, can be installed at appropriate locations near the CNC lathe bearings. When installing the sensor, ensure that it is in close contact with the bearing and use appropriate fixtures to secure the sensor. By connecting sensors to thermometers or control systems, CNC lathes can continuously monitor bearing temperature and perform real-time recording and analysis.

3. Observe the status of the grease: The increase in CNC lathe bearing temperature is often related to poor lubrication. Therefore, by observing the condition of the grease, we can initially judge whether the bearing temperature is normal. If there are abnormal phenomena in CNC lathe grease, such as deterioration, solidification or overflow, it may mean that the bearing temperature is too high. At this time, the bearings and lubrication system should be checked in time, and corresponding maintenance or replacement measures should be taken.

When performing temperature detection, you need to pay attention to the following points:

1. Select an appropriate temperature sensor and installation location for the CNC lathe to ensure that it can accurately reflect the temperature changes of the spindle bearing.

2. When using composite measurement methods on CNC lathes, attention should be paid to the conversion and correction of the two methods to ensure the accuracy of the measurement results.

3. During the installation and use of CNC lathes, attention should be paid to the protection and maintenance of the temperature sensor to avoid damage and errors.

4. Regularly inspect and calibrate the CNC lathe measurement system to ensure that it is in good working condition.

In addition, according to some practical experience, the bearing temperature is generally limited to a temperature increase of no more than 45°C. During monitoring, if the temperature of the bearing is found to exceed 70~80℃, the machine should be stopped immediately for inspection.

In short, by comprehensively applying the above methods and precautions, CNC lathes can effectively detect the bearing temperature of CNC lathes and ensure the safe and stable operation of the machine tools.
