1. High machining precision and stable machining quality;
2. It can carry out multi coordinate linkage and process parts with complex shape;
3. When processing aluminum alloy die castings, 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, can choose favorable processing amount, and has 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;
6. Higher quality requirements for operators and higher technical requirements for maintenance personnel.
