Technical Field

[0001] The utility model relates to the technical field of machining centers, in particular to a gantry machining center with two machine heads, a three-axis head and a five-axis head. Background Art

[0002] Gantry machining center refers to a machining center in which the axis of the spindle Z axis is set perpendicular to the worktable. The overall structure is a large-scale machining center with a double column and a top beam forming a gantry structure frame, and there is a crossbeam in the middle of the double column. It is especially suitable for machining large workpieces and workpieces with complex shapes.

[0003] Some gantry machining centers have both three-axis and five-axis heads, which can complete more complex machining operations;
