CNC vertical lathes can be processed in a variety of ways, depending on the shape, material and processing requirements of the workpiece. The following are some common CNC vertical lathe processing methods:

1. Length feed (long axis turning): CNC vertical lathe can feed along the axial direction of the workpiece to achieve turning of the length of the workpiece, and is suitable for processing workpieces such as rotating shafts and camshafts.
2. Surface feed (for turning): CNC vertical lathe can perform feed motion on the workpiece surface to achieve shape processing of the workpiece surface, such as plane turning, chamfering, etc.
3. Single-point thread processing: CNC vertical lathe can process internal and external threads through a single-point tool to achieve the processing of workpiece threads, including straight threads, oblique threads, etc.
4. Drilling and tapping: CNC vertical lathes can perform drilling and tapping operations, and hole processing and thread processing can be performed with appropriate tools.
5. High-speed milling: Some CNC vertical lathes can also rotate the spindle to achieve high-speed milling operations. This is useful when light milling or workpieces with complex contours need to be machined.
6. Grooving and grooving: CNC vertical lathes can perform grooving or grooving operations through the tool to process the internal or external grooves of the workpiece.
7. Partial turning: CNC vertical lathe can realize partial turning of the workpiece through different positions and angles of the tool, such as end faces, fillets, etc.

These are just some common processing methods of CNC vertical lathes. The specific processing methods also depend on the functions and configurations of CNC vertical lathes, as well as the type of workpieces that need to be processed. Before performing CNC machining, it is recommended to understand the machine tool's functions and user manual in detail, and set up and program according to specific machining requirements.
