How to design the structure of machining center castings?

    How to design the structure of the machining center casting is to consider the comprehensive design of materials science, mechanics, structure and so on. For example, the door type vertical machining center machine casting has good static stiffness. It should pay attention to the reasonable selection of the structural form of the casting. For example, the machine tool casting adopts a closed complete box structure to improve the overall bending and torsion resistance, and can make the whole of the casting. Complete, reduced processing, but the difficulty of casting increases, and some machining center castings use closed sections, reasonable selection and layout of partitions and ribs, minimize joint surfaces, and improve contact stiffness between castings, for example When the need is met, the knife is left blank, which reduces the processing cost and reduces the weight of the casting. The longitudinal baffle mainly improves the bending rigidity of the casting; the transverse baffle mainly improves the torsional rigidity of the casting; the oblique baffle has the effect of improving the bending rigidity and torsional rigidity of the casting. In the design, to see which power is dominant, it is necessary to adopt the corresponding structure to hedge the corresponding power.
