1. Using high-performance castings for manufacturing and secondary tempering process to eliminate internal stress in the structure;
2. Adopting high rigidity imported ball screws and roller tracks to improve fast moving speed;
3. The large-span column structure and weighted base improve the overall structural rigidity of the machine;
4. Three axis screw pre stretching and casting scraping process to ensure good accuracy;
5. High power spindle cooling circulation system reduces spindle thermal deformation.
