To prolong the service life of the vertical lathe, the following measures can be taken:

1. Regular maintenance and maintenance: It is very important to carry out regular maintenance and maintenance of machine tools. This includes cleaning, lubricating, tightening critical parts, replacing worn parts, etc. Regular maintenance keeps machine tools up and running, reduces breakdowns and damage, and prolongs machine life.
2. Use appropriate cutting parameters: Reasonably set and control cutting parameters, including cutting speed, feed rate, cutting depth, etc. Excessive cutting force or high-speed cutting may cause additional load and wear on the machine tool and tool, so it is necessary to select appropriate cutting parameters according to the requirements of the material and workpiece.
3. Select high-quality tools and tool materials: choose high-quality and suitable tools and tool materials to improve cutting efficiency and quality, and reduce tool wear and damage. Regularly inspect and replace worn knives and avoid using damaged knives.
4. Control temperature and cooling lubrication: Reasonable cooling and lubrication can reduce cutting temperature, reduce friction and wear. Keep the lubrication system working normally, replace the cooling lubricant in time, and keep the working area clean.
5. Avoid overloading and overuse: Avoid excessive load operations on the machine tool to prevent machine tool wear and damage. Reasonably arrange the production plan and give the machine tool an appropriate rest time.
6. Reasonably arrange the environment of the machine tool: try to avoid the impact of the harsh environment on the CNC vertical lathe, such as vibration, dust, moisture, etc. Keep the environment where the machine tool is located clean and dry, and provide appropriate protective measures.
7. Training and guidance to operators: Provide training and guidance to operators to make them understand the correct operation methods and common troubleshooting steps. Reasonable operation and maintenance of machine tools is an important factor to ensure the service life of machine tools.
8. Regular inspection and monitoring: Regularly check the working status of each component of the machine tool, and monitor the performance and accuracy of the machine tool. Find and solve problems in time to avoid potential failures.

To sum up, prolonging the service life of the vertical lathe requires comprehensive consideration of multiple factors such as machine tool maintenance, tools, operation, and environment, and taking appropriate measures to maximize the protection of the machine tool and improve its working efficiency and life.
