CNC machine tool is the abbreviation of digital control machine tool. It is an automatic machine tool equipped with program control system. The control system can logically process the program with control code or other symbolic instructions and decode it, so as to make the machine tool operate and process parts.

Compared with ordinary machine tools, CNC machine tools have the following characteristics:

High machining precision and stable machining quality;

It can carry out multi coordinate linkage and process parts with complex shape;

When machining parts are changed, generally only the NC program needs to be changed, which can save production preparation time;

The machine tool itself has high precision and rigidity, can choose favorable processing amount, and has high productivity (generally 3 ~ 5 times that of ordinary machine tools);

The machine tool has a high degree of automation, which can reduce the labor intensity;

Higher quality requirements for operators and higher technical requirements for maintenance personnel.
