Column Moving Gantry Type Machining Center

This column moving gantry type machining center is positioned for "heavy cutting and high torque." It offers a 1.5-meter Z-axis travel and a 5.2-meter Y-axis travel, with a 4.2-meter gantry width. The highlight is the spindle unit, manufactured by LYE, delivering 50-61 kW of power, a rated torque of 3585 N·m, and a maximum torque of 4500 N·m. This means when machining high-strength alloys, it can take aggressive depth of cuts. Thanks to the large-lead precision ball screws and dual-gear pre-loaded backlash elimination reducer, power transmission is rock solid.

The confidence of this column moving gantry type machining center lies in its ability to handle both "rough, ugly jobs" and "fine, precise work" without compromise. Because the worktable is fixed, you can drop a 30-ton blank on it without worrying about the table warping. Moreover, this column moving gantry machining center adopts a structure where the entire gantry frame moves as a whole. This gives it a low center of gravity and excellent anti-tipping ability, meaning its rigidity won't collapse even when machining at the edges. Combined with its 4.2-meter gantry width and over 3 meters of machining height, it completes multi-face machining in one setup, saving secondary alignment time and preventing error accumulation from repeated loading/unloading. Many seasoned machinists in heavy industry praise this column moving gantry machining center for its rock-solid, steady sound when pushing large flat surfaces, with no signs of fluttering. This stability is its greatest value, which is exactly why this type of column moving gantry machining center is widely recognized in the ultra-heavy manufacturing sector.

Column moving gantry type machining center is mainly used for automotive cover dies, heavy-duty general machinery boxes, wind turbine gearbox housings, marine deck machinery, and rail transit bogies. It performs milling, boring, drilling, rigid tapping, reaming, and counterboring. When paired with optional milling heads, it can achieve multi-angle five-face machining.

• Heavy-duty loads & attachment heads: Standard with high torque; optional Taiwan MING YANG fully automatic right-angle heads, universal heads, extension heads, and flat heads (all supporting 5-degree indexing, with head magazines).
• Tool magazine expansion: Upgrade to a 60-station ATC magazine.
• Coolant pressure upgrade: Optional CTS 30 BAR (30-bar high-pressure center through coolant).
• System & travel: Sunk-in foundation options available; can upgrade to higher-end Siemens systems; Z-axis travel can be customized.

Before leaving the factory, strict laser interferometer compensation is performed on the machine to ensure the positioning and repeatability accuracy across the full travels of X/Y/Z/W meets the agreement standards. Additionally, for this high-torque machine, high-standard hand-scraping contact checks are performed on the LYE ram's guideways. It undergoes full-load cutting tests on trial workpieces to verify chip evacuation and temperature rise, ensuring you receive a "fully run-in" machine in top condition.

The heaviest lifting component for this machine weighs about 30 tons. The buyer must prepare the foundation in advance and prepare a three-phase four-core cable (4*35mm²) and a clean, dry air source according to the confirmation sheet. Upon arrival, we handle the installation and commissioning after unloading, and we train your operators on-site until they can work independently. Please plan your site and foundation well in advance, as 90 days of inability to install due to site reasons will be considered automatic acceptance of the machine.
