The fuselage structure is independently optimized and designed by finite element analysis,and the internal stress is fully eliminated by heat treatment after casting to ensure the long-term accuracy and stability of the fuselage structure.

All contact surfaces of the fuselage ate scraped and ground to eliminate internal forces and false data to ensure long-term stability of the geometric accuracy of the fuselage space.

The three-axis screw is designed with a precision pre-drawing process,which can effectively suppress the thermal temperature rise and ensure the positioning accuracy and repeatability of the machine tool.

The headstock adopts the design of no counterweight to avoid counterweight vibration and inertial lag;with the increase of the servo motor,the high-speed response of the machine tool is realized.

Large-span herringbone column;widen the span of the base and the y-axisrail;increase the distance between the sliders of the spindle box;the span of the slider of the slider of the worktable and the length of the worktable meet the Rea-sonable space layout such as the best principle of Bessel ensures the powerful and stable cutting ability of the spindle.
