对称双立柱结构：采用双立柱龙门式布局，横梁与两侧立柱形成闭环框架，通过箱型筋板或米汉纳铸铁铸造工艺增强抗弯抗扭刚度。

适合轻切削：路合金/铜/预制钢（HRC≤40）的精细加工，硬质合金需要降低切深/进给，适用小型模具、医疗、小型叶轮与涡轮。

Symmetrical double-column structure: Utilizes a double-column gantry layout, with the crossbeam forming a closed-loop frame with the side columns. The rigidity against bending and torsion is enhanced through box-type rib plates or Mihana cast iron casting processes.

Suitable for light cutting: Fine machining of road alloys/copper/precast steel (HRC ≤ 40). For hard alloys, cutting depth/feed rate should be reduced. Ideal for small molds, medical applications, small impellers, and turbines.
