HL-630 features a fully supported design throughout the entire machine, guaranteeing exceptional rigidity. The Y-axis column is equipped with twin roller-type linear guideways. The machine base utilizes a heavily ribbed, reinforced design that provides stable casting rigidity and superior shock absorption capabilities. This ensures the base remains completely deformation-free, allowing the spindle's full performance to be perfectly realized during machining operations.

Additionally, the column adopts a gantry-type (portal) full-frame structure, and the casting body itself features a box-type structural design to further ensure maximum structural stability.
