For the classification of CNC lathes according to the purpose of processing technology, there are four types, namely metal cutting, metal forming, special processing, measurement, drawing, etc., and have their unique functions. The details are as follows.

Metal cutting refers to CNC lathes that use various cutting processes such as cnc turning, milling, boring, drilling, grinding, planing, and gear processing. It is divided into the following two categories.

(1) Ordinary CNC machine tool

This type of CNC machine tool is the same as the traditional general-purpose machine tool. It has lathes, milling machines, drilling machines, boring machines, and grinders. Its processability is similar to that of general-purpose machine tools.

(2) Machining center machine tool

The machining center machine tool is a CNC machine tool with an automatic tool changer. It is characterized by a tool magazine with an automatic tool changer. By automatically changing the tool, the workpiece can be automatically and continuously on a cnc machine after one clamping.

Multi-processes such as sex milling, boring, drilling, reaming, tapping, etc. on the machining surface of the workpiece Common boring and milling machining centers mainly for processing box parts and turning centers that can complete almost all processes of various rotating body parts.
Now, some CNC machine tools for compound processing concentrate on multi-process, multi-blade, and compound process processing in one device.
