1. CNC machining precision of fine metal shaft is high, with stable processing quality;
2. Multi coordinate linkage can be carried out, and parts with disordered shapes can be processed;
3. When the fine 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. It can choose favorable processing amount and high production rate (generally 3-5 times that of general machine tools);
5. The machine tool has a high degree of automation, which can reduce the labor intensity;
The short cutting tool is the main feature of CNC fine machining. The short cutting tool will obviously reduce the deviation of cutting tool, and then achieve outstanding surface quality, avoid rework, reduce the use of electrode, and shorten the EDM processing time. When considering the five axis machining, it is necessary to consider the principle of using the five axis machining die: finish the whole workpiece machining with the shortest cutting things as possible, also including cutting programming, clamping and machining time, but get more perfect surface quality.
