Maintaining a small CNC vertical lathe is one of the keys to ensuring its long-term stable operation and extending its service life. The following are some suggestions for maintaining small CNC vertical lathes:

1. Regular cleaning: It is very important to clean the CNC vertical lathe regularly. Cleaning the cutting oil residue, metal chips and dust on the surface and inside of the machine tool and keeping the machine tool clean and tidy will help reduce the wear and failure of machine tool parts.

2. Lubrication and maintenance: Regularly inspect and maintain the lubrication system of the CNC vertical lathe. Keep the lubricating oil clean and sufficient to ensure good lubrication effect at each lubrication point to prevent parts from being worn or damaged due to friction.

3. Check the electrical components: Regularly check the electrical components of the CNC vertical lathe, including motors, sensors, terminals, etc. Make sure the electrical connections are good and not loose or oxidized to prevent machine tool shutdown or damage caused by electrical faults.

4. Tools and tool holding devices: Regularly check the status of tools and tool holding devices to ensure that the tools are sharp and installed correctly, and that the clamping device is firm and reliable. Replace severely worn tools in a timely manner to avoid safety accidents or processing quality problems caused by tool breakage or misalignment.

5. CNC system maintenance: Regularly maintain and update the CNC system, including checking the power supply, control card, sensors and other components of the CNC system to ensure its normal operation and stability. Timely update the software and firmware of the CNC system to improve the functional performance and safety of the system.

6. Troubleshooting: Carry out regular troubleshooting and maintenance of machine tools, promptly repair discovered faults and problems, and avoid expanding faults or damaging other parts.

7. Operator training: Provide necessary training and guidance to operators, teach correct operation methods and maintenance skills, enhance operators' awareness of the use and maintenance of machine tools, and reduce damage caused by misoperation and improper use.

Through the above maintenance measures, the service life of small CNC vertical lathes can be effectively extended, production efficiency can be improved, maintenance costs can be reduced, and processing quality and safety can be ensured.
