CNC milling machine is in the general milling machine developed on the basis of an automatic processing equipment, the two processing technology is basically the same, the structure is also somewhat similar. CNC milling machines are divided into two categories without a magazine and a magazine. One of the CNC milling machine with a magazine is also known as a machining center.

CNC milling in addition to ordinary milling machine with the characteristics of the following, there are the following characteristics: 1, parts of the processing of strong adaptability, flexibility, and can be processed contour shape is particularly complex or difficult to control the size of the parts, such as mold parts, shell parts;

2, can be processed ordinary machine can not be processed or difficult to process the parts, such as the mathematical model described in the complex curve parts and three-dimensional surface parts of the surface;

3, can be processed once fixture positioning, the need for multi-channel processing of the parts;

4, the processing of high precision, stable and reliable processing quality, numerical control device pulse equivalent is generally 0.001mm, high-precision CNC system up to 0.1μm, in addition, CNC machining also avoid the operator's operational errors;

5, a high degree of automation, can reduce the operator's labor intensity. Is conducive to production management automation;

6, high production efficiency, CNC milling machine generally do not need to use special fixtures and other special process equipment, in the replacement of the workpiece only need to call stored in the CNC device processing procedures, clamping tools and adjust the tool data can be, thus greatly reducing the production cycle. Second, CNC milling machine with milling machine, boring machine, drilling machine function, so that a high degree of concentration, greatly improving the production efficiency. In addition, the CNC milling machine spindle speed and feed speed are stepless speed, it is conducive to select the best cutting amount.
