1. The CNC machining precision of the precision metal shaft is high, and the machining quality is stable;
2. Multi-coordinate linkage can be carried out, and parts with complex shapes can be processed;
3. When the precision hardware CNC machining parts 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 high rigidity, can choose a favorable processing amount, and has high productivity (generally 3 to 5 times that of ordinary machine tools);
5. The machine tool has a high degree of automation, which can reduce labor intensity;
The use of short cutting tools for CNC precision machining is the main feature of precision hardware parts. Short tools will significantly reduce tool deviation, thereby obtaining a good surface quality, avoiding rework, reducing the amount of electrode used, and shortening the processing time of EDM. When considering five-axis machining, the goal of using five-axis machining molds must be considered: the shortest possible cutting tool is used to complete the machining of the entire workpiece, which also includes reducing programming, clamping and machining time to get a more perfect surface quality .
