CNC vertical lathe is a high-precision machine tool that can complete various complex turning processes. According to different processing needs, CNC vertical lathe can use a variety of turning methods. Here are some common turning methods:

1. Rough turning: Rough turning is a method of quickly removing material and is mainly used for rough machining of parts. During rough turning, the cutting depth is large and the cutting speed is fast, allowing a large amount of material to be removed quickly.

2. Finish turning: Finish turning is a fine turning method, mainly used for the finishing of parts. During the finishing turning process, the cutting depth is small and the cutting speed is slow, which can ensure the quality and accuracy of the machined surface.

3. Grooving turning: Grooving turning is a turning method that produces grooves of various shapes and sizes on the workpiece. During the grooving turning process, the tool moves along a specific path to cut the desired groove.

4. Thread turning: Thread turning is a turning method that produces threads on the workpiece. During the thread turning process, the tool cuts at a specific rotation speed and feed rate to process threads that meet the requirements.

5. End turning: End turning is a method of turning the end face of the workpiece. During the end face turning process, the tool cuts at a specific rotation speed and feed rate to process the end face that meets the requirements.

The above are several common turning methods for CNC vertical lathes. Different turning methods can be used for different processing needs.
