There is a certain relationship between the price and accuracy of CNC vertical lathes, but it is not a simple direct relationship. Several factors will affect the price of CNC vertical lathe and its level of accuracy. Here are some influencing factors:

1. Process and design quality: The manufacturing process and design quality of a CNC vertical lathe are important factors that affect its accuracy. High-quality workmanship and design often enable greater machine tool accuracy, but this can also increase manufacturing costs, affecting the price of the equipment.
2. CNC system: The CNC system of CNC vertical lathe is crucial for the control and positioning of machine tools. High-performance CNC systems usually provide higher motion control accuracy, but may also increase the price of the equipment.
3. Materials and manufacturing standards: The use of high-strength, high-rigidity materials and strict manufacturing standards can improve the stability and accuracy of CNC vertical lathes. However, this may increase manufacturing costs.
4. Accessories and configuration: The configuration and accessories of CNC vertical lathe will also affect its price and accuracy. For example, high-precision spindles, positioning systems, and automation features can increase the price of the equipment.
5. Brands and manufacturers: CNC vertical lathes produced by different brands and manufacturers may differ in price and accuracy. Well-known brands usually have a better reputation and quality assurance, but may be priced accordingly.

Overall, higher accuracy usually correlates with higher price, but this is not an absolute rule. Sometimes, some manufacturers may provide relatively high-precision CNC vertical lathes while maintaining relatively low prices by optimizing processes and improving efficiency. When purchasing a CNC vertical lathe, it is best to consider the accuracy, performance, brand reputation and other factors of the machine tool based on actual needs and budget to select suitable equipment.
