In addition to the characteristics of ordinary milling machines, CNC milling has the following characteristics:

1. The CNC Milling machine has strong adaptability and flexibility, and can process parts with particularly complicated contour shapes or difficult to control dimensions, such as mold parts and shell parts;

2. It can process parts that cannot be processed or difficult to be processed by ordinary machine tools, such as complex curved parts described by mathematical models and three-dimensional space curved parts;

3. It can process parts that need to be processed in multiple procedures after one clamping and positioning;

4. High processing accuracy, stable and reliable processing quality, the pulse equivalent of the numerical control device is generally 0.001mm, and the high-precision numerical control system can reach 0.1μm. In addition, CNC processing also avoids the operation errors of the operator;

5. The high degree of production automation can reduce the labor intensity of the operator. Conducive to production management automation;

6. High production efficiency, CNC milling machines generally do not require the use of special process equipment such as special fixtures, and only need to call the machining program, clamping tool and tool data adjustment stored in the CNC device when replacing the workpiece, thus greatly reducing production cycle. Secondly, CNC milling machine has the functions of milling machine, boring machine and drilling machine, which makes the process highly concentrated and greatly improves production efficiency. In addition, the spindle speed and feed speed of the CNC milling machine are continuously variable, so it is beneficial to choose the best cutting amount;
