Overview
The Makino MAG4 is the largest machine in Makino's MAG series, a massive 5-axis horizontal machining center designed for the biggest aerospace aluminum structural components in commercial and military aviation. This machine represents the top of Makino's aluminum-focused 5-axis technology, targeting full-size wing skins, large fuselage panels, and oversized structural forgings that exceed the capacity of the MAG3 family.
Axis travel extends to 3,000 x 2,500 x 1,000 mm (118.1 x 98.4 x 39.4 in) on X/Y/Z, providing an enormous work envelope for the largest aerospace structural parts. The 1,000 mm Z-travel is significantly deeper than the MAG3's 700 mm, accommodating thicker structural components and deeper pocketing operations. The A-axis tilts from +30 to -120 degrees while the C-axis provides full 360-degree continuous rotation, both driven by high-torque direct-drive motors.
The standard spindle runs at 16,000 RPM with an HSK-A100 taper delivering 80 kW (107 hp) continuous power — a substantial increase over the MAG3's 55 kW. This additional power sustains higher material removal rates during the extended roughing operations that large structural parts require. The pallet system supports loads up to 4,000 kg (8,818 lb), accommodating the heavy fixtures and large aluminum forgings typical of this machine class.
The horizontal spindle orientation with a massive chip evacuation system handles the extreme chip volumes generated during sustained high-speed aluminum machining operations. Cross-roller guides on all axes maintain rigidity and accuracy across the very large work envelope.
Rapid traverse hits 50 m/min (1,969 ipm) on all axes. The MAG4 weighs approximately 60,000 kg (132,277 lb) and runs on Makino's Professional 6 control. The 160-tool ATC supports the most complex aerospace structural parts. Competitors include the Starrag Ecospeed F 2560, Jobs Linx systems, and custom gantry solutions.

Strengths & Limitations
Strengths
- 3,000 x 2,500 x 1,000 mm travel handles the largest aerospace aluminum structural components produced in the industry
- 80 kW continuous spindle power sustains the highest aluminum material removal rates through extended roughing operations on large parts
- 1,000 mm Z-travel provides significantly more depth than the MAG3's 700 mm, accommodating thicker structures and deeper pocketing
- 160-tool ATC supports the most complex multi-operation aerospace structural parts without interruption
- 4,000 kg pallet load capacity handles the heaviest aerospace forgings and fixture assemblies
- Horizontal chip evacuation system handles the extreme chip volumes generated during sustained high-speed aluminum production
- 60,000 kg machine mass provides extraordinary dynamic stability for consistent cutting across the entire large envelope
Limitations
- Price point of $2.5M-$4M limits the MAG4 to major aerospace OEMs and large Tier 1 suppliers with sustained large-part production
- 60,000 kg weight and massive footprint require purpose-built facility space with heavy-duty foundations
- Aluminum-focused design limits versatility — using this machine for titanium or steel is possible but not cost-optimal
- Machine represents a long-term facility commitment — installation, foundation, and integration costs make relocation impractical
- Lead times can extend to 18-24 months due to the custom casting and assembly requirements

Frequently Asked Questions
01
New MAG4 machines typically price between $2,500,000 and $4,000,000 depending on configuration. A base machine with 80 kW spindle, 160-tool ATC, and pallet system starts around $2,500,000. Full automation integration, coolant systems, foundation work, and installation can push total project cost past $4,000,000. These are major capital investments typically justified by multi-year aerospace production contracts.
02
The MAG4 significantly exceeds the MAG3 in every dimension: X-travel grows from 1,800 to 3,000 mm, Y from 1,500 to 2,500 mm, and Z from 700 to 1,000 mm. Spindle power jumps from 55 to 80 kW. Tool capacity increases from 120 to 160. Machine weight nearly doubles from 32,000 to 60,000 kg. The MAG3 handles most standard-size structural parts; the MAG4 is for parts that simply don't fit in anything smaller.
03
Traditional gantry mills offer large X/Y travel but typically with only 3-axis or limited tilting head capability and vertical spindle orientation. The MAG4 provides full simultaneous 5-axis machining with horizontal spindle orientation for superior chip evacuation. For complex aerospace structural parts with contoured surfaces, angled features, and deep pockets, the MAG4's 5-axis capability eliminates multiple setups and delivers better surface finish.
04
The MAG4 requires a purpose-built installation space: approximately 12,000 x 8,000 mm of floor area with reinforced concrete foundation (typically 600-800mm thick, isolated from the building structure). Ceiling height must accommodate the chip conveyor and overhead crane for fixture/pallet handling. Dedicated electrical service, coolant recycling systems, and chip processing equipment are needed. Most MAG4 installations are planned during new facility construction.
