The Skymach BR2516 CNC Gantry Machining Center is an ultra-heavy double-column bridge machining center engineered for large-format automotive stamping dies, aerospace structural frameworks, wind energy components, and heavy shipyard fabrications. Built on a monolithic stress-relieved HT300 cast iron foundation weighing 19.0 t (19,000 kg), the BR2516 combines massive spindle torque (236 N.m) with massive table load capacities up to 5.0 t (5,000 kg).
Comprehensive Machining Capabilities
- Heavy Roughing & Deep Pocketing: High-torque BT50 spindle effortlessly handles large face milling cutters, heavy slotting, deep-hole drilling, and rigid tapping in tough alloy steels.
- Extra-Large Mold & Die Manufacturing: Symmetrical portal bridge structure resists multi-axis cutting loads, maintaining fine 3D contour surface accuracy across expansive 2,500 x 1,600 x 750 mm travels.
- Enhanced Vertical Ram Performance: Z-axis is guided by 4 heavy-duty linear roller rails and balanced by dual nitrogen cylinders for rapid, vibration-free vertical dynamics.
Key Engineering Highlights
- Monolithic Gantry & Bed Castings: Integrally cast bridge and base provide unmatched structural dampening and geometric stability under continuous heavy cutting.
- Dual Nitrogen Balance System: Counterbalances vertical ram weight, eliminating backlash and thermal elongation.
- Precision Motion System: High-rigidity preloaded roller linear guideways and ground ball screws deliver rapid traverse speeds and sub-micron repeatability.

Frequently Asked Questions
What is the warranty period for your machines?
We offer a standard 12-month warranty on all our CNC machines, covering the spindle assembly, ball screws, linear guides, CNC controller, and servo drive motors. Extended warranties and customized service plans are available upon request.
Do you provide overseas installation and training?
Yes. Our engineers are available for overseas dispatch to assist with machine installation, commissioning, and comprehensive operator training at your facility. Every machine also ships with English manuals, circuit diagrams, and video setup guides.
What is the typical lead time for an order?
Standard catalog machines ship within 30 days. Custom configurations — such as oversized spindle bores, extended bed lengths, or integrated 4th-axis rotary tables — typically ship within 60 days.
How do you handle spare parts requests?
We maintain a comprehensive inventory of standard spare parts. Genuine replacement components are dispatched via international express (DHL/FedEx) within 48 hours, ensuring minimal downtime for your production line.
