CNC vertical lathe is a kind of mechanical equipment widely used in the industrial field. In daily use and maintenance of mechanical equipment, it is often necessary to maintain the spindle of CNC vertical lathes. Let’s learn more about the spindle maintenance methods of CNC vertical lathes.

1. Spindle cleaning
When performing spindle maintenance, the spindle needs to be cleaned first. Use cleaning tools to clean the spindle surface for better subsequent maintenance. When cleaning the spindle, you should be careful not to use too hard cleaning tools to avoid scratching the surface of the spindle. Similarly, you also need to pay attention to the use of cleaning tools to avoid affecting the mechanical properties of the spindle.

2. Spindle lubrication
After cleaning the spindle surface, the spindle needs to be lubricated to ensure normal operation of the spindle and extend the service life of the spindle. Lubricating oil is usually used to lubricate the spindle. The type and amount of lubricating oil need to be selected according to the material of the spindle and the usage scenario. When lubricating the spindle, you should also be careful not to use excessive lubricating oil to avoid affecting the performance of the spindle. Likewise, lubricants should be replaced regularly based on their service life.

3. Spindle tool replacement
In the use of CNC vertical lathes, the tools will inevitably wear or lose sharpness. At this time, the tool needs to be replaced. When replacing tools, you need to pay attention to selecting appropriate tools and replace them according to actual needs. After changing the tool, the spindle needs to be calibrated to ensure the position accuracy of the tool.

4. Insulation of spindle
The CNC vertical lathe needs to maintain a certain temperature during operation, which has an impact on the service life and mechanical performance of the spindle. Therefore, when using CNC vertical lathes, the spindle needs to be insulated. This is usually achieved by reducing the heat dissipation of the spindle or by insulating the spindle surface. Of course, this needs to be selected based on the material of the spindle and the usage scenario.

5. Spindle status monitoring
In the use of CNC vertical lathes, the status of the spindle needs to be monitored regularly. Through condition monitoring, spindle problems can be discovered early and corresponding maintenance measures can be taken. Usually condition monitoring methods include vibration measurement, noise measurement, temperature measurement, etc. When performing condition monitoring, it is necessary to formulate corresponding monitoring plans based on actual needs, analyze the monitoring data, and take corresponding measures in a timely manner.

Based on the above content, the maintenance of the spindle of CNC vertical lathe needs to choose the corresponding method based on the actual situation. When maintaining, attention to detail is required to achieve the best results and extend the service life of the spindle.
