The Skymach BR1311A CNC Gantry Machining Center is a high-precision bridge-type double-column machining center engineered for mold bases, precision stamping dies, aerospace structural parts, and heavy automotive tooling. Its monolithic one-piece casting bed and integrated bridge frame provide superior geometric stiffness, excellent vibration dampening, and long-term machining accuracy.
Comprehensive Machining Capabilities
- High-Precision Die & Mold Contouring: Designed for continuous 3D surface machining of plastic injection molds, die-casting dies, and forging tools.
- Heavy Roughing to Mirror Finishing: Heavy-duty 45 mm roller linear guideways deliver high load capacity and rigidity for aggressive metal removal followed by fine finishing.
- Dynamic Z-Axis Motion: Equipped with 6 preloaded guide sliders and dual nitrogen balancing cylinders for smooth, high-speed vertical ram response.
Key Engineering Highlights
- Monolithic Casting Structure: Stress-relieved cast iron base and gantry frame ensure zero deformation under heavy cutting loads.
- 45mm Heavy-Duty Roller Rails: Roller linear guideways on all 3 axes provide superior load capacity and vibration absorption compared to ball-type rails.
- Dual Nitrogen Balance System: Ensures ultra-stable Z-axis acceleration and deceleration, preventing thermal elongation and spindle vibration.

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.
