CNC vertical lathes are suitable for processing many types of workpieces, especially those that have rotational symmetry or require axial machining. Here are some common workpiece types suitable for CNC vertical lathe processing:

1. Shaft parts: CNC vertical lathes are suitable for processing various types of shaft parts, such as drive shafts, steering shafts, roller shafts, etc. It can achieve high-precision axial machining, chamfering, threading and other operations.
2. Threaded parts: CNC vertical lathes can be used to process various types of threaded parts, such as internal threads and external threads. It can achieve high-precision thread processing, including common thread forms and special thread forms.
3. Ring-shaped workpieces: CNC vertical lathes are suitable for processing ring-shaped workpieces, such as flywheel shells, sprockets, bearing seats, etc. It has the characteristics of rotational symmetry, and can realize circumferential machining and contour machining by using the rotating table and cutting tools of the vertical lathe.
4. Connecting parts: CNC vertical lathe is suitable for processing various types of connecting parts, such as flanges, sleeves, bearing seats, etc. Through the processing of CNC vertical lathe, high-precision processing of connecting holes and processing contours of connecting parts can be achieved.
5. Gantry parts: CNC vertical lathes can be used to process workpieces with gantry structures, such as bridge components, skateboards, machine tool beds, etc. It has strong rigidity and stability and is suitable for cutting and processing large workpieces.

The most suitable processing method and parameters need to be determined based on the size, shape and requirements of the specific workpiece, as well as the processing capabilities of the CNC vertical lathe. At the same time, appropriate tools, fixtures and processing techniques should be selected according to the actual situation to ensure processing quality and efficiency.
