Preventing CNC vertical lathe operation errors is crucial, the following are some common preventive measures and suggestions:

1. Training and education: ensure that all operators receive sufficient training and education to understand the operating principles, safety requirements and operating procedures of CNC vertical lathes. Training includes knowledge in machine operation, programming and maintenance.
2. Follow the operating procedures: operate the CNC vertical lathe in accordance with the correct operating procedures and regulations. Make sure that operators understand and abide by all operating procedures, including machine tool start, stop, switching working mode, emergency stop and other operating procedures.
3. Program verification: Before the actual processing operation, program verification and simulation operation are carried out. The correctness and safety of the program can be checked through the simulated operation, and potential problems and errors can be avoided.
4. Regular maintenance and maintenance: CNC vertical lathes need regular maintenance and maintenance to ensure the normal operation and safety performance of the machine tool. Check the lubrication system, electrical system, tool clamping device, etc., and repair and replace the parts that need to be repaired in time.
5. Use of safety devices: CNC vertical lathes are usually equipped with a variety of safety devices, such as emergency stop buttons, protective covers, light curtains, etc. Operators should use these safety devices correctly and ensure their normal working condition.
6. Workpiece fixation and clamping: Before installing the workpiece on the CNC vertical lathe for processing, ensure that the fixation and clamping of the workpiece is safe and reliable. Use proper fixtures and fixture systems and ensure a safe distance from the workpiece to the tool.
7. Monitoring and inspection: The operator should monitor the running status and processing process of the CNC vertical lathe at all times, and pay attention to observe any abnormal conditions. Regularly check the functions and performance of the machine tool, as well as the wear and looseness of the machine tool surface.
8. Safe operating environment: maintain a clean and tidy operating environment, and ensure that there are no sundries and obstacles in the operating area. Maintain a safe area around the machine tool to prevent other personnel from entering the operating area.

These measures can help reduce the risk of errors in CNC vertical lathe operations and improve operational safety. However, each enterprise and operator should carry out a specific risk assessment according to the actual situation, and take appropriate measures to ensure the safety of the operation process.
