Using advanced computer technology and optimization design methods from the United States, the dimensions of various reinforcing ribs, bed frames, guide rails, and other major components distributed inside the machine tool are designed to carry the maximum load with the lowest possible weight. Using casting optimization design software to analyze and inspect the structural form and dimensions of castings. Mihanna cast iron is integrally cast, wear-resistant, and treated with internal force relaxation to achieve high anti vibration and high rigidity. Its shock absorption capacity is 10 times higher than ordinary cast iron, improving the stability of the machine tool. The machine tool base is designed with a distance shaped force distribution.
