In addition to the characteristics of the ordinary milling machining, CNC milling has the following characteristics:
1, the parts processing adaptability, flexibility, can processing contour shape, especially complex or difficult to control the size of parts, such as mold parts, shell parts, etc.;
2, can processing ordinary machine tools can not be processed or difficult to process parts, such as using mathematical model to describe complex curve parts and three-dimensional space curved surface parts;
3, can process a clamping, positioning, the need for multi-channel processing parts;
4. high precision machining, stable and reliable quality, pulse equivalent numerical control device is generally 0.001mm, high-precision CNC system can reach 0.1 M, in addition, the CNC machining also avoids the operation loss
5, the production of high degree of automation, can reduce the labor intensity of the operator. It is beneficial to automation of production management;
6, the production efficiency is high, the CNC milling machine generally do not need to use special fixtures and other special processing equipment, processing procedures, in replacement of the workpiece simply call stored in the NC device in the clamping tool and can adjust the cutter data, thus greatly shorten the production cycle. Secondly, CNC milling machine with milling machine, boring machine, drilling machine function, so that the process is highly concentrated, greatly improving production efficiency. In addition, the spindle speed and feed speed of CNC milling machine are stepless speed change, so it is beneficial to select the best cutting parameters;
