1. The casting is made of high-grade, low S.P content cast iron, melted in an electric furnace, and molded with resin sand, which has good rigidity and shock absorption ability

2. Adopting hardened sliding guide rail, precision grinding, and pasting wear-resistant material guide rail plate, with low damping and good wear resistance XK714 adopts a raised and widened column, with a Z-axis travel of 150mm higher to meet the fourth axis rotation requirements of box type parts

3. Accurate balancing of the spindle box, smooth and fast bi-directional displacement; The layout of the Y-axis guide rail is reasonable to ensure machining accuracy

4. All three axes are equipped with C3 grade high-precision ball screws, precision pre tightening process, optimized transmission rigidity, and reduced thermal deformation

5. Integrated high rigidity and high-precision spindle components, original imported NSK combination bearings, imported synchronous belt drive, low temperature rise, low noise, and dynamic balance accuracy up to G1.0 level
