High-precision valve processing usually requires the use of high-precision CNC vertical lathes. These lathes should have a range of features and functions to meet the requirements of valve machining:

1. High-precision processing capabilities: CNC vertical lathes should have high-precision processing capabilities and be able to meet the size and surface quality requirements required for valve processing.

2. Stable rigid structure: The structure of the lathe should be designed to be stable and have good rigidity to ensure that no vibration and deformation occur during the processing.

3. Advanced CNC system: Lathes should be equipped with advanced CNC systems that can achieve precise processing of complex parts and have efficient programming and operating interfaces.

4. Reliable spindle and transmission system: The spindle and transmission system should have high reliability and high precision to ensure stability and precision during processing.

5. Automation functions: Lathes should have automation functions, such as automatic tool changing systems, automatic measurement systems, etc., to improve production efficiency and processing accuracy.

6. Multi-axis control: Some complex valve parts may require multi-axis control, so the lathe should have multi-axis control functions and be able to control multiple axial movements at the same time.

7. Tool management system: High-precision valve processing usually requires the use of different types of tools. The lathe should be equipped with a tool management system that can easily manage and replace tools.

8. Reliable cooling system: During the processing process, the temperature of the tool and workpiece needs to be kept stable, so the lathe should be equipped with a reliable cooling system to ensure processing quality and tool life.

9. Good human-machine interface: The operating interface of the CNC system should be friendly and intuitive, so that operators can easily program, monitor and adjust the machining process.

10. Continuous maintenance and support: Choose a manufacturer with good after-sales service and technical support to ensure that the lathe can continue to operate stably and solve problems in a timely manner.

To sum up, high-precision valve processing requires the use of CNC vertical lathes with high precision, stability and reliability, as well as advanced CNC systems and automation functions to meet the requirements of complex parts processing. Choosing the right lathe is crucial to ensuring processing quality and production efficiency.
