To extend the life of a CNC vertical lathe, the following measures can be taken:

1. Regular care and maintenance: Carry out regular maintenance and upkeep of the machine tool according to the machine tool manufacturer's recommendations. This includes cleaning and lubricating various parts of the machine tool, and inspecting and replacing worn parts to ensure proper operation of the machine tool and reduce the possibility of failure.
2. Reasonable use: Comply with the operating procedures and instructions of the machine tool, operate the machine tool reasonably, and avoid damage to the machine tool caused by overload operation or sudden start and stop of the machine tool. Avoid cutting parameters that are too large or too small to reduce wear and load on the machine tool.
3. Regular calibration: Regularly calibrate the CNC vertical lathe to ensure its movement accuracy and the parallelism and verticality of the worktable. This helps maintain machine tool accuracy and stability, extending service life.
4. Regularly check the circuit and electrical system: The circuit and electrical system of the CNC vertical lathe are susceptible to voltage fluctuations and other electrical problems during work. Regularly check the connection status of circuits and electrical systems to ensure the normal operation of the electrical parts.
5. Reasonable installation and environmental control: Install the machine tool correctly to prevent the machine tool from being affected by external shocks, vibrations and other factors. At the same time, control the environment in which the machine tool is located to ensure that the machine tool operates in a dry, clean, and stable environment to avoid damage to the machine tool from dust and moisture.
6. Handle faults and problems in a timely manner: When machine tool faults or problems occur, handle and repair them in a timely manner to prevent the fault from expanding and causing more serious damage. Carry out regular health checks on machine tools and resolve problems as soon as possible to ensure the normal operation of machine tools.

The above are some common measures that can help extend the life of CNC vertical lathes. However, specific measures may vary depending on factors such as machine tool model, manufacturer requirements and operating environment, so it is recommended to take appropriate measures based on the specific conditions of the machine tool and the manufacturer's recommendations.
