5 Axis Gantry Machine Tool

The MBU 35 Series is a high-gantry 5-axis machining center developed by Five-Axis CNC. It features an overhead bed paired with dual longitudinal saddles and a "box-in-box" crossbeam. The worktable remains stationary while the gantry moves across the top. Standard equipped with a Siemens system and an IBAG 5-axis head, it boasts a rapid traverse of 40 m/min on the X/Y/Z axes, specifically designed for high-efficiency precision machining in aerospace and mold industries.

Product Introduction
 
Product Description
 

The confidence of this 5 Axis Gantry Machine Tool lies in its unconventional structure. It hangs the spindle inside a closed rigid frame to do the work. Because the workpiece weight sits on the fixed table, the machine is completely unaffected by part weight during high-speed movement. Paired with the IBAG 5-axis head, it achieves large-angle rotations of ±110°/±360° on the A/C axes, making complex 3D curved surface machining as smooth as cutting tofu. It also comes standard with full closed-loop linear scales, which eat up mechanical deviations in real-time, ensuring highly stable precision.

Product Features
 
01/

Fast traverses: The X/Y/Z axes come standard with a 40 m/min rapid traverse. In a 5-axis gantry, this speed is impressive and saves a huge amount of time during long air-cutting moves.

02/

Unafraid of thermal deformation: The crossbeam utilizes a "box-in-box" symmetrical structure, with the spindle positioned exactly at the center of the crossbeam and ram. When ambient temperatures fluctuate, the spindle's center shift is minimized.

03/

Full closed-loop control: Encoder feedback (standard full closed-loop) is installed on the X/Y/Z guideways, allowing the system to compensate for mechanical backlash and thermal expansion in real-time, removing the need for operators to manually adjust tool offsets based on guesswork.

04/

Load capacity doesn't care about the part: With the overhead gantry design, all moving components are above the worktable. Even when an 8-ton workpiece sits on the table, it doesn't affect the machine's dynamic cutting performance.

05/

Open-top full enclosure: Uses full sheet metal protection (without a roof). It protects operators from chips and coolant while allowing workshop cranes to directly load large workpieces.

 
Product Advantages
 

When machining complex impellers, high-temperature alloys, and large high-precision molds, the biggest advantage of this 5 Axis Gantry Machine Tool lies in its "unmanned operation" capability. It supports optional automatic loading/unloading robots, combined with in-line inspection and automatic workpiece calibration, achieving true lights-out manufacturing. For the core challenges of 5-axis simultaneous machining, this 5 Axis Gantry Machine uses optional linear motors and dual-gear backlash elimination mechanisms to completely eliminate backlash, resulting in ultra-high positioning accuracy. For factory owners, investing in a 5 Axis Gantry Machine isn't just about part accuracy; it's about securing higher-difficulty contracts in competitive bidding.

Product Application
 

5 Axis Gantry Machine Tool is widely used in aerospace (structural parts, impellers, blades), automotive molds (cover dies, die-casting molds), precision medical devices, and complex curved surface parts in high-end energy equipment. It excels at completing 5-axis simultaneous milling, drilling, rigid tapping, and counterboring in a single setup, handling various high-value-added precision components.

 

 
Customization Options
 

Spindle & Milling Heads:

Standard IBAG Mepro 5-axis head, optional Kessler 5-axis head. Larger tool magazines or ATC systems can also be selected.

Automation Integration:

Supports interfaces for automated systems such as robot loading/unloading and on-machine inspection.

Function Module Expansion:

Supports optional right-angle heads, universal heads, rotary tables, or even multi-spindle systems for specific multi-station machining requirements.

Travel Extension:

Z-axis travel can be upgraded to 1500mm (optional), and the spindle nose distance can be extended to 1700mm to accommodate taller parts.

After-Sales Service
 

We provide a 12-month full machine warranty. During the warranty period, manufacturing defects are repaired on-site free of charge (excluding human damage). We offer lifelong spare parts supply. Upon delivery, our engineers will handle on-site installation, commissioning, and free operator training until you can work independently (our travel and accommodation costs are on us). Due to the segmented high-gantry structure, the heaviest lifting component is about 30 tons. We will provide detailed foundation drawings and send a dedicated engineer to guide on-site unloading and assembly. Please note: If installation is impossible within 90 days due to buyer's site reasons, the machine will be deemed automatically accepted, so please prepare the foundation and site in advance based on the drawings.
