1. CNC machining of precision metal shafts has high precision and stable processing quality;

2. Multi-coordinate linkage can be performed, and parts with complex shapes can be processed;

3. When CNC machining parts of precision hardware are changed, generally only the CNC program needs to be changed, which can save production preparation time;

4. The machine tool itself has high precision and rigidity. It can choose favorable processing amount and high productivity (generally 3 to 5 times of ordinary machine tools)

5. High degree of machine tool automation can reduce labor intensity;

CNC precision machining using short cutting tools is the main feature of precision hardware parts. Short tools will significantly reduce tool deviation, thereby obtaining good surface quality, avoiding rework, reducing the use of welding rods, and shortening EDM processing time. When considering five-axis machining, the goal of using five-axis machining molds must be considered: to complete the machining of the entire workpiece with the shortest cutting tools possible, including reducing programming, clamping and machining time while achieving a more perfect surface quality .
