Gantry-type Series
Chansin Gantry Series delivers massive work envelope machining capabilities (up to X-axis travel), engineered for monolithic part processing in aerospace, energy, and heavy equipment industries.
Rigid double-column construction with thermal symmetry technology eliminates deflection during high-force cutting of steel alloys and composites, ensuring micron-level accuracy over full travel.
Integrated multi-spindle configurations and automatic head changers enable simultaneous 5-face machining, reducing production cycles by 60% for complex geometries like turbine housings and press dies.

Features
Massive Work Envelope with Uncompromising Stability
Feature: Large X/Y/Z travels supported by a rigid double-column (gantry) structure and high-grade cast iron construction.
Benefit: Machines oversized, monolithic parts—like mold bases, machine frames, or aerospace structures—in a single setup, eliminating repositioning errors and ensuring unparalleled dimensional stability during heavy-cutting operations.
Superior Precision at Scale
Feature: Advanced thermal symmetry design, laser-calibrated feedback systems, and optional screw cooling.
Benefit: Maintains micron-level accuracy across the entire worktable, even during long-duration machining. This is critical for producing large components that must fit together perfectly.
Powerful Heavy-Duty Machining Capability
Feature: High-torque, direct-drive spindles and hardened box ways or oversized linear guides.
Benefit: Excels at aggressive material removal on tough alloys (steel, iron, titanium) with high metal removal rates (MRR), significantly reducing roughing time without sacrificing tool life or part quality.
Configurable for Specialized Applications
Feature: Modular design with a wide array of optional heads, accessories, and table configurations (T-slots, vacuum, etc.).
Benefit: Can be tailored from a general-purpose heavy-duty mill to a specialized solution for composites, aerospace parts, or energy sector components.
Optional
Application
Aerospace & Defense Industry
Applies To: Manufacturers of wing spars, fuselage panels, engine mounts, and landing gear components.
Reason: The massive work envelope handles large airframe structures, while the rigidity and precision ensure compliance with stringent aerospace tolerances.
Mold & Die Industry (Large Format)
Applies To: Producers of automotive injection molds, die-casting molds for engine blocks, and large plastic injection molds.
Reason: Enables the complete machining of massive mold bases in one setup, ensuring perfect alignment between cavities and cores and a superior surface finish.
Energy, Heavy Machinery & Transportation
Applies To: Manufacturers of wind turbine components (hubs, gearboxes), valve bodies for oil & gas, locomotive parts, and industrial machine frames.
Reason: Capable of milling, drilling, and boring on very large, heavy castings and weldments that are impossible to accommodate on a standard VMC or HMC.
Professional Job Shops Serving Heavy Industries
Applies To: Contract manufacturers who bid on large-part projects and need a versatile “jobbing” machine.
Reason: The gantry’s open table design provides exceptional flexibility for fixturing unusually large or heavy workpieces, making it the ideal solution for high-mix, large-part production.
