[0002] Gantry machining centers are widely used machine tools in industrial manufacturing, characterized by high precision, high efficiency, and high reliability. The Z-axis of the gantry machining center is perpendicular to the worktable. Its overall structure is a large machining center with a portal frame frame consisting of double columns and a top beam, with a crossbeam in the middle of the double columns. It is particularly suitable for machining large and complex-shaped workpieces.

[0003] The existing machining center has a relatively complex structure and an unreasonable design. After long-term use, dust will fall on the slide rail, affecting the sliding of the slider, causing the slider to wear more quickly, loosen, and affect the positioning accuracy. In addition, the base of the machining center is relatively unstable during operation. When machining large workpieces, the vibration generated will cause the machining center to deviate, affecting the machining accuracy. Utility Model Content
