1. CNC machining precision of precision metal shaft is high, with stable machining quality;
2. It can carry out multi coordinate linkage and process parts with complex shapes;
3. When the precision hardware CNC machining parts are changed, generally only the NC program needs to be changed, which can save the production preparation time;
4. The machine tool itself has high precision and rigidity, so it can choose favorable processing amount and high productivity (generally 3-5 times that of ordinary machine tools);
5. The machine tool has a high degree of automation, which can reduce the labor intensity;
CNC precision machining uses short cutting tools, which is the main feature of precision hardware parts. The short cutting tool will obviously reduce the deviation of cutting tool, so as to obtain good surface quality, avoid rework, reduce the usage of welding rod, and shorten the processing time of EDM. When considering the five axis machining, the goal of using the five axis machining die must be considered: to finish the machining of the whole workpiece with the shortest cutting tool possible, including reducing the programming, clamping and machining time, but also to get a more perfect surface quality.
