According to different spindle positions, CNC lathes are divided into vertical CNC lathes and horizontal CNC lathes. Vertical CNC lathes are used for turning disk parts with larger turning diameters; horizontal CNC lathes are used for turning parts with longer axial dimensions or small disk parts.

According to different costs and functions, it can be divided into economical CNC lathes, ordinary CNC lathes and turning machining centers.

Economical CNC lathe: a simple CNC lathe formed by reforming the turning feed system of an ordinary lathe with a stepping motor and a single-chip microcomputer. The cost is low, the degree of automation and functions are relatively poor, and the machining accuracy of turning is not high. It is suitable for turning machining of rotary parts with low requirements.

Ordinary CNC lathe: a CNC lathe that is specially designed in structure according to the requirements of turning processing and is equipped with a general CNC system. The numerical control system has strong functions, high degree of automation and processing accuracy, and is suitable for turning processing of general rotary parts.

Turning machining center: On the basis of ordinary CNC lathes, tool magazines and other devices are added. In addition to general turning, it can also perform radial and axial milling, surface milling, and radial holes whose centerline is not at the center of rotation of the part. Drilling and other processing.
