During the processing of CNC lathes, excessive temperature of the bearings will seriously affect the performance and accuracy of the machine tool. In order to solve this problem, we need to deeply understand its causes and propose targeted solutions.

Bearing high temperature is mainly caused by the following two factors:

1. Frictional heating: During the operation of the bearing, a large amount of heat is generated due to friction between the various components. If the heat is not dissipated in time, the temperature of the bearing will rise.

2. Insufficient lubrication: Problems with the bearing lubrication system, such as insufficient lubricating oil or poor quality, lead to increased bearing friction and increased temperature.

To address the causes of the above problems, we propose the following solutions:

1. Optimize bearing design: By improving the ball and raceway design of the bearing, the friction coefficient is reduced and the heat generated by friction is reduced.

2. Strengthen lubrication management: Check the lubrication system regularly to ensure that the lubricating oil is sufficient and the quality is up to standard. At the same time, the lubricating oil should be replaced regularly according to work needs.

3. Install cooling device: Install cooling device, such as cooling fan or coolant circulation system, near the bearing to take away the heat generated during the operation of the bearing in time.

4. Real-time monitoring and alarm: The bearing temperature is monitored in real time through the temperature sensor. Once the temperature exceeds the safe range, the alarm is immediately issued and corresponding measures are taken.

Through the implementation of the above solutions, the operating temperature of CNC lathe bearings can be effectively reduced, the stability and service life of the machine tool can be improved, and the enterprise's production efficiency can be effectively guaranteed.
