CNC lathes can usually choose from different CNC systems, including FANUC, Siemens, etc. For vertical CNC lathes that require high precision, high efficiency and customizable solutions, there are several key points to consider:

1. Machine tool structure: Choose a machine tool structure suitable for high-precision processing, such as a vertical structure with high rigidity and low vibration to ensure processing accuracy and stability.

2. CNC system: CNC system is one of the key factors affecting the accuracy and efficiency of machine tools. Both FANUC and Siemens systems feature high precision and efficiency, and can be customized according to customer needs.

3. Customized functions: Considering that different customers may have different processing needs, machine tool functions can be customized according to customers' specific requirements, such as specific processing techniques, degree of automation, etc.

4. Degree of automation: Improving the degree of automation can improve production efficiency. You can consider optional automation devices, such as automatic tool changers, automatic measurement systems, automatic feeding systems, etc., to reduce manual intervention and improve production efficiency.

5. Processing accuracy guarantee: By selecting high-precision sensors, control systems and precision processing techniques, we ensure that the machine tool can meet the processing accuracy requirements required by customers.

6. Regular maintenance and upkeep: No matter how superior the performance of the machine tool is, regular maintenance and upkeep are still crucial to ensure long-term stable operation of the machine tool and maintain high accuracy.

When communicating with machine tool manufacturers, you should learn more about their customization capabilities, technical support, after-sales services, etc. to ensure that the selected equipment can meet customers' high-precision, high-efficiency and customized needs.
