Overview
The Makino UX6i is a large-envelope intelligent wire EDM that combines Makino's proven UX6 platform with next-generation adaptive technology. It is built for shops cutting larger die plates, mold components, and aerospace parts that demand both generous travel and precision — all backed by smart automation features that maximize uptime and reduce operator dependency.
Axis travel measures 650 x 450 x 420 mm (25.6 x 17.7 x 16.5 in) on X/Y/Z, providing a large working envelope that handles substantial die plates and mold blocks. U and V axes deliver +/-80 mm (+/-3.1 in) of taper offset for steep-angle and tall-workpiece taper cutting. The worktable spans 900 x 650 mm (35.4 x 25.6 in) and supports workpieces up to 900 x 650 x 420 mm (35.4 x 25.6 x 16.5 in) at a maximum weight of 1,000 kg (2,205 lb).
The 'i' intelligent platform features Makino's adaptive discharge generator, which continuously monitors cut conditions and adjusts spark parameters in real time to optimize speed and finish quality. This technology pays dividends on tall workpieces and varying cross-sections where fixed parameters would cause wire breakage or inconsistent finishes. Surface finish capability reaches 0.1 um Ra (4 uin Ra), and positioning accuracy is rated at +/-0.002 mm (+/-0.00008 in).
Wire diameter range spans 0.10 to 0.30 mm (0.004 to 0.012 in). Taper cutting handles angles up to +/-30 degrees at reduced height. The enhanced Hyper-i control includes predictive maintenance monitoring, cutting time estimation, and expanded technology databases.
The large submerged cutting tank with temperature-controlled dielectric maintains thermal stability across the generous work zone. Intelligent automatic wire threading handles even difficult re-threading situations in deep cavities and pre-machined features. The UX6i competes with the Sodick ALN800G, Mitsubishi MV4800R, and GF Machining Solutions CUT 600 in the large-format precision wire EDM segment. New pricing typically ranges from $220,000 to $310,000.

Strengths & Limitations
Strengths
- Large travel envelope (650 x 450 x 420 mm) handles substantial die plates and mold blocks that mid-size wire EDMs cannot accommodate
- Adaptive discharge generator optimizes cutting parameters in real time for consistent results on varying cross-sections and tall workpieces
- 1,000 kg workpiece capacity supports heavy die steel and mold base plates without weight concerns
- +/-80 mm U/V axis offset enables steep taper cuts on tall workpieces
- Predictive maintenance monitoring reduces unplanned downtime in production environments
- Surface finish to 0.1 um Ra covers even demanding die/mold finish requirements
Limitations
- Large footprint and 5,800 kg machine weight require substantial floor space and potentially reinforced foundations
- Premium pricing ($220K-$310K) represents a significant investment that must be justified by workpiece size requirements
- Higher wire consumption and dielectric volume increase ongoing operating costs versus smaller machines
- The large tank takes longer to fill and temperature-stabilize at startup compared to compact models
- Overkill for shops whose work consistently fits within 400 x 300 mm envelopes

Frequently Asked Questions
01
New UX6i machines typically price between $220,000 and $310,000 depending on configuration and options. The intelligent features add roughly $20,000-$30,000 over the base UX6. As a newer model, used UX6i availability is limited, but early units have been listed in the $140,000-$200,000 range.
02
The UX6i offers substantially larger travel (650 x 450 x 420 mm vs 370 x 270 x 220 mm), more than triple the workpiece weight capacity (1,000 kg vs 300 kg), and wider U/V axis offset (+/-80 mm vs +/-50 mm). Both share the adaptive discharge generator and enhanced Hyper-i control. Choose the UX6i when your work regularly exceeds the UX3i's envelope or weight limits.
03
Makino's adaptive discharge generator continuously monitors the electrical conditions at the spark gap and adjusts parameters in real time. This prevents wire breakage on changing cross-sections, maintains consistent surface finish quality regardless of workpiece height variations, and optimizes cutting speed automatically. It is particularly valuable on tall workpieces and complex geometries where fixed parameters would cause problems.
04
Yes. With 420 mm Z-axis travel and the adaptive discharge generator, the UX6i excels at tall workpiece cutting where maintaining stable conditions through the full height is critical. The +/-80 mm U/V offset also enables taper cutting on tall parts. This combination makes it effective for extrusion dies, tall mold components, and stacked workpieces.
05
The UX6i requires approximately 3.5 x 3.0 m (11.5 x 9.8 ft) of floor space including service clearances, plus space for the dielectric unit and power supply. At 5,800 kg, verify your floor can handle the static load. A reinforced concrete floor rated for at least 2,000 kg/m2 is recommended.
