Overview
The Makino MAG.A12/A20H represents the largest platform in Makino's MAG series, designed for 5-axis machining of the biggest aerospace structural components including wing spars, fuselage frames, and large landing gear assemblies. This machine bridges the gap between traditional 5-axis machining centers and dedicated gantry-style profilers, offering the precision of a machining center with the work envelope needed for full-scale aerospace structures.
Axis travel extends to 2,500 x 2,000 x 1,600 mm (98.4 x 78.7 x 63.0 in) on X/Y/Z, providing the reach needed for large-scale structural components. The A-axis tilting head provides 150 degrees of tilt (+30 to -120) with a full 360-degree continuous C-axis, both direct-drive for fast, backlash-free positioning. Two spindle options are available: a 16,000 RPM HSK-A100 at 55 kW for aluminum-focused work, and a high-torque 10,000 RPM variant delivering 80 kW (107 hp) with 600 Nm for titanium production.
The 1,250 x 1,000 mm (49.2 x 39.4 in) pallet accommodates massive workpieces with a table load capacity of 4,000 kg (8,818 lb). A 180-tool automatic tool changer provides extensive tool storage for complex parts requiring many different cutters. Rapid traverse runs at 40 m/min (1,575 ipm) on linear axes.
Weighing approximately 55,000 kg (121,254 lb), the machine delivers exceptional rigidity through sheer mass and Makino's optimized structural design. The Makino Pro 6 control manages the complex 5-axis kinematics and offers advanced thermal compensation to maintain accuracy across the large work envelope. This machine competes with the Starrag Ecospeed F 2040, Jobs LinX Compact, and large-format DMG Mori DMU/DMC platforms in the mega-scale aerospace machining segment.

Strengths & Limitations
Strengths
- 2,500 x 2,000 x 1,600 mm travel envelope handles the largest aerospace structural components in a single setup
- Dual spindle options (16K aluminum / 10K high-torque titanium) allow configuration for specific material requirements
- 4,000 kg table load capacity supports massive titanium forgings and heavy fixturing systems
- 180-tool ATC enables machining of complex parts with many features without manual tool intervention
- 55,000 kg machine mass provides exceptional rigidity for maintaining accuracy across the large work envelope
- Direct-drive A/C axes deliver fast, precise positioning even under heavy cutting loads
Limitations
- Price range of $2.5M-$4.0M represents a major capital investment requiring long-term production contracts to justify
- Massive footprint and 55,000-kg weight demand extensive facility preparation including reinforced foundations
- 40 m/min rapid traverse is slower than smaller MAG models, adding non-cutting time on large traverses
- Lead times for this class of machine can extend 12-18 months, requiring significant advance planning
- Limited secondary market availability makes used acquisition difficult

Frequently Asked Questions
01
A new Makino MAG.A12/A20H ranges from approximately $2,500,000 to $4,000,000 depending on spindle configuration, automation level, and options. The high-torque titanium spindle option adds a significant premium. Full turnkey installations with pallet automation, high-pressure coolant, and specialized fixturing can exceed $4,000,000. These machines are typically acquired through direct negotiation with Makino for specific production programs.
02
The A12 and A20H designations refer to different pallet size and capacity configurations within the same platform family. The A20H typically denotes the high-torque heavy-duty variant optimized for titanium production with increased table load capacity and the 80 kW spindle option. Specific configurations are typically customized to the customer's application requirements in consultation with Makino's application engineering team.
03
At 55,000 kg, the MAG.A12/A20H requires a purpose-built reinforced concrete foundation designed to handle both static weight and dynamic cutting forces. Foundation depth, reinforcement specifications, and isolation requirements are determined through a site survey by Makino's installation engineering team. Most installations require a dedicated foundation slab separate from the building floor to prevent vibration transmission.
04
The MAG.A12/A20H offers higher accuracy and better surface finish than most gantry profilers, with the work envelope approaching gantry-class dimensions. Gantry profilers typically offer even larger X-axis travel and can handle longer components, but the MAG's enclosed machining center design provides better thermal stability, chip management, and overall part quality. For components that fit within the 2,500 mm X-travel, the MAG generally delivers superior results.
