5 Axis Gantry Milling Machine
Product Description
This 5 axis gantry milling machine utilizes a "fixed gantry, moving table" structural design, with columns secured to the left and right sides of the bed and a crossbeam mounted atop the columns. The base is constructed from a new mineral material; compared to traditional cast iron, this material offers superior vibration absorption during machining and ensures greater geometric accuracy retention over long-term use. The structural layout is symmetrical to ensure uniform thermal distribution and minimize thermal deformation. The ram houses a high-speed motorized spindle and a dual-swivel milling head, enabling ±110° (or ±100°) A-axis tilting and ±360° C-axis rotation, facilitating 5-axis simultaneous machining of inclined surfaces, deep cavities, and complex contours. Notably, the spindle head is equipped with a dual-hydraulic-cylinder counterbalance mechanism, preventing jerking or "tool drop" caused by gravity during Z-axis vertical movement.

Product Features
Dual-Swivel Milling Head:
The A and C axes utilize a direct-drive structure, offering rapid response speeds and a maximum rotation speed of 30 rpm. The accuracy of the A/C axis encoders meets the VDI3441 standard, guaranteeing positioning and repeatability within 6 arc-seconds-ideal for high-precision machining of complex curved surfaces.
Cooling and Chip Removal Design:
The system utilizes both air and liquid cooling to accommodate various cutting tools and materials. An integrated automatic chip removal system, combined with internal and external guideway protection, prevents the accumulation of chips and coolant on the machine, thereby reducing wear on the guideways and ball screws.
Spindle Cooling System:
The spindle features an internal constant-temperature cooling unit. This prevents thermal expansion caused by heat buildup during prolonged high-speed cutting-which would otherwise compromise machining accuracy-while also extending the service life of the spindle bearings.
Inspection and Linear Scales:
Standard full-closed-loop linear scales provide real-time position feedback. This effectively eliminates errors caused by thermal expansion/contraction or backlash in the ball screw drive, ensuring actual positioning accuracy closely matches theoretical values.
Product Advantages
Material and Vibration Damping:
The bed and column are constructed from a new mineral material with a damping coefficient significantly higher than that of standard cast iron. This allows for substantial absorption of cutting vibrations when machining difficult materials (such as high-hardness steel or titanium alloys), helping to protect tools and improve workpiece surface finish.
Load Capacity and Rigidity:
The 5 axis gantry milling machine boasts a table load capacity of up to 20 tons, allowing large, heavy workpieces to be machined directly without frequent lifting or process transfers. This minimizes the time costs and accuracy risks associated with workpiece handling and repeated clamping..
Thermal Symmetry:
The symmetrical structural design, combined with the mineral material's low coefficient of thermal expansion, ensures consistent geometric accuracy even amidst significant workshop temperature fluctuations. This eliminates the common issue found in traditional machines where machining precision varies between the start and end of the day.
Product Applications
This 5 axis gantry milling machine is primarily designed for sectors such as aerospace, rail transportation, automotive mold making, and large-scale equipment manufacturing.
Typical workpieces include: aero-engine casings, large aluminum alloy structural components, large die-castings for new energy vehicles, automotive body panel molds, marine propellers, and various large, complex curved-surface parts requiring 5-axis simultaneous machining.
Optional Customization
In addition to the standard configuration, the following options are available based on specific processing requirements:
Wide Product Range
Tool Magazine System: While not included as standard, high-capacity disc-type or chain-type tool magazines can be installed to enable automatic tool changing and reduce manual intervention.
Wide Applications
Tool Setter and Probe: High-precision infrared probes (e.g., Renishaw) and automatic tool setters can be selected to facilitate automated workpiece alignment and tool setting, thereby reducing non-productive time.
High Strength
CNC System Upgrade: The standard configuration features the "ONE" system; however, customers can opt for mainstream CNC systems such as SIEMENS, HEIDENHAIN, or FANUC based on their preferences.
Professional
High-Pressure Coolant: For deep-hole drilling or machining difficult-to-cut materials, a high-pressure coolant system with through-spindle delivery can be selected.
