The specifications and models of CNC vertical lathes are very diverse to suit different processing needs and workpiece sizes. The following are some common CNC vertical lathe specifications and parameters:

1. Maximum turning diameter: This is the maximum workpiece diameter that the CNC vertical lathe can accommodate. Common specifications include 300mm, 400mm, 500mm, 600mm, etc.
2. Maximum turning length: This is the maximum workpiece length that the CNC vertical lathe can process. Common specifications include 500mm, 800mm, 1000mm, 1500mm, etc.
3. Maximum processing diameter: This is the maximum processing diameter that the CNC vertical lathe can achieve. Common specifications include 200mm, 300mm, 400mm, 500mm, etc.
4. Spindle bore diameter: This is the diameter of the through hole inside the spindle of a CNC vertical lathe, which determines the diameter of the material that can be processed and the size of the tool. Common specifications include 52mm, 65mm, 80mm, 105mm, etc.
5. Spindle speed range: This is the speed adjustment range of the CNC vertical lathe spindle. Common specifications include 2000rpm, 3000rpm, 4000rpm, 6000rpm, etc.
6. Turret type: The turret type of CNC vertical lathe can be a feed turret or a magazine type turret. The feed-type turret usually has fewer tool positions and is suitable for small batch production and prototype processing; the magazine-type turret usually has multiple tool positions and can automatically change tools, and is suitable for mass production and complex process processing.
7. Numerical control system: There are many options for numerical control systems used in CNC vertical lathes, such as Fanuc and Siemens. Different CNC systems have different functions, programming languages and operating interfaces.

These specifications and parameters are just some common examples, and actual CNC vertical lathe specifications will vary based on needs and manufacturers. When selecting a CNC vertical lathe, you need to select the appropriate specifications and configuration based on specific machining needs, workpiece size and material.
