Precision CNC lathes can be divided into the following types according to their movement modes:

1. Linear motion lathe: The main motion of the linear motion lathe is performed on a linear track. On this type of lathe, the workpiece typically moves along the X and Z axes, and the tool moves on the Y axis. This structure is suitable for workpieces that need to be processed on a flat surface.

2. Rotary motion lathe: The main movement of the rotary motion lathe is rotation around the axis. On this type of lathe, the workpiece usually rotates on the spindle and the tool moves on the X and Z axes. This structure is suitable for workpieces that require circumferential processing, such as rotating shafts, bearings, etc.

3. Compound motion lathe: The compound motion lathe combines linear motion and rotary motion and can perform multi-axis motion in different directions. This type of lathe usually has higher flexibility and processing capabilities, and can meet the processing needs of various complex workpieces.

4. Vertical motion lathe: The main motion of the vertical motion lathe is perpendicular to the work surface. On this type of lathe, the workpiece is usually fixed on the table and the tool moves up and down on the spindle. This structure is suitable for processing long and thin workpieces, as well as symmetrical parts.

These different types of CNC lathes can be selected according to processing needs and workpiece characteristics to achieve the best processing results.
