For the classification of CNC lathes according to the purpose of cnc machining 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.

1. Metal cutting

Refers to CNC lathes that use various cutting processes such as 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 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.

2. Metal forming

refers to CNC machine tools that use extrusion, punching, pressing, drawing and other forming processes. Among the CNC metal forming machine tools, there are CNC punching machines, CNC pipe bending machines, CNC pipe bending machines, CNC cutting machines, CNC spinning machines, CNC presses, etc.

3. Special processing

CNC special processing equipment includes CNC cutting machine, CNC electric discharge machining equipment, CNC flame cutting machine, spot welding machine, CNC laser processing machine, etc.

4. Measurement and drawing

Non-processing equipment also uses a large number of CNC technologies, such as CNC coordinate measuring machines, automatic plotters, assembly machines, industrial robots, CNC tool setters, etc.
