CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool equipped with a program control system. This control system is capable of logically processing programs with control codes or other symbolic instructions, and decoding them to enable machine tool action and machining of parts.

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

● High machining accuracy and stable machining quality;

● Can perform multi coordinate linkage and process parts with complex shapes;

When changing the machining parts, it is generally only necessary to change the CNC program, which can save production preparation time;

The machine tool itself has high accuracy and rigidity, and can choose favorable processing quantities, resulting in high productivity (generally 3-5 times that of ordinary machine tools);

High degree of machine tool automation can reduce labor intensity;

High requirements are placed on the quality of operators and higher technical requirements are placed on maintenance personnel.
