Overview

The Mazak INTEGREX i-400 is the bigger brother in Mazak's INTEGREX i-Series lineup, built for shops that need multi-tasking capability on medium-to-large parts that the i-200 can't swing. It shares the same DNA—full 5-axis mill-turn in a single setup—but steps up with a beefier 30 kW (40 hp) main turning spindle, longer 1,519 mm (59.8 in) machining length, and 615 mm (24.2 in) of X-axis travel to handle larger work envelopes.

You're looking at a 658 mm (25.9 in) max machining diameter with a 10-inch chuck and 102 mm (4.0 in) bar capacity through the A2-8 spindle nose. The main spindle runs to 3,300 RPM—lower than the i-200's 5,000 RPM, but that's the tradeoff for the larger spindle bore and heavier-duty bearings needed for bigger bar stock and chucked work. The milling spindle hits 12,000 RPM with 22 kW (30 hp) through a Capto C6 interface, and there's a 20,000 RPM option for shops pushing lighter finishing cuts.

The B-axis covers 240 degrees (-30 to +210) with 0.0001-degree resolution, same as the i-200. Paired with 250 mm (9.84 in) of Y-axis travel and continuous C-axis rotation, you can attack complex geometries from virtually any angle without pulling the part. Z-axis travel stretches to 1,585 mm (62.4 in) for long shaft work, and rapids hit 50 m/min (1,969 ipm) on X and Z to keep non-cutting time tight.

The standard 36-tool ATC with Capto C6 shanks handles most jobs, with 72 and 110-tool magazine options for complex aerospace or energy parts that need deep tool libraries. An NC tailstock with 1,562 mm of travel supports long, slender shafts during heavy cuts.

Current-generation machines run on the MAZATROL SmoothAi control with Ai Thermal Shield for active compensation during long-cycle jobs. Older units from 2012-2018 came with Matrix 2 or SmoothX controls. At roughly 15,500 kg (34,172 lb), the i-400 needs serious floor space and foundation work—it's not a machine you're dropping into a tight job shop bay.

Direct competitors include the DMG Mori NLX 2500/700 and CTX beta 1250, plus the Okuma Multus B250II. The i-400 sits between the i-200 and the larger i-500/i-600 models in Mazak's lineup. New machines typically run $350,000-$550,000 depending on configuration, with used units from 2014-2020 trading between $150,000 and $350,000.

Strengths & Limitations

Strengths

Full 5-axis multi-tasking with a 12,000 RPM Capto C6 milling spindle delivering 22 kW (30 hp), providing true machining center performance rather than turret-mounted live tooling
102 mm (4.0 in) bar capacity and 10-inch chuck handle significantly larger bar stock and chucked work than the i-200's 65 mm limit, opening up heavier aerospace and energy sector parts
1,519 mm (59.8 in) machining length with NC tailstock support handles long shafts, landing gear components, and oil-field parts that won't fit on smaller multi-tasking machines
240-degree B-axis with 0.0001-degree resolution and roller cam drive provides zero-backlash positioning for complex angular features across the full swing range
50 m/min (1,969 ipm) rapids on X and Z keep non-cutting time low when cycling between turning and milling operations on long-cycle production parts
36-tool standard ATC expandable to 110 tools means complex multi-operation parts don't stall for manual tool changes, critical for done-in-one aerospace work
Mazak's massive global install base and North American manufacturing in Florence, KY means parts availability and trained service techs are easier to source than with smaller European builders

Limitations

3,300 RPM main spindle is noticeably slower than the i-200's 5,000 RPM, limiting high-speed turning performance on smaller-diameter aluminum and non-ferrous work
15,500 kg (34,172 lb) machine weight requires substantial foundation work and rigging planning, with a footprint over 5 meters long that limits placement in smaller shops
New price of $350K+ is a serious capital investment that only pays off when you're consistently eliminating three or more setups per part across significant production volume
Programming complexity is high even for experienced CNC operators; expect 3-6 months ramp-up time, and post processors for INTEGREX machines are notoriously difficult to source and configure
B-axis accuracy can drift over time and periodic laser calibration from Mazak service at $250+/hour is recommended every 12-18 months for shops holding tight tolerances

Best For

Aerospace manufacturers machining large flight components, landing gear parts, and turbine hardware that need turning, milling, and drilling consolidated into single-setup processing Energy sector shops producing oil and gas components with complex OD/ID features, cross-holes, and long shaft geometries that would require four or more setups on conventional equipment Job shops running high-mix work on medium-to-large parts where the 102 mm bar capacity and 1,519 mm machining length exceed what an i-200 can handle Defense contractors producing ordnance, guidance, and structural components where done-in-one processing eliminates refixturing errors on tight-tolerance parts Production environments running lights-out with bar feeders up to 102 mm (4.0 in) diameter, NC tailstock, and automated part handling for unattended multi-shift operation Shops stepping up from the INTEGREX i-200 that need larger work envelopes without jumping to the i-500/i-600 class machines

Frequently Asked Questions

01 What does a new Mazak INTEGREX i-400 cost?

Base price starts around $350,000. Production-ready configurations with the 20,000 RPM milling spindle, high-pressure through-spindle coolant, and expanded 72 or 110-tool magazine typically run $420,000-$550,000. Used i-400s from 2014-2020 sell for $150,000-$350,000 depending on hours, spindle condition, control generation, and installed options. When shopping used, check both turning and milling spindle bearing condition carefully.

02 How does the INTEGREX i-400 compare to the i-200?

The i-400 steps up with a larger 10-inch chuck (vs 8-inch), 102 mm bar capacity (vs 65 mm), 30 kW main spindle (vs 22 kW), and significantly more Z-axis travel at 1,585 mm (vs 1,020 mm). The tradeoff is a slower 3,300 RPM main spindle (vs 5,000 RPM) due to the larger spindle bore. The i-400 also weighs 15,500 kg vs 9,200 kg, so it needs more floor space and heavier foundations. Choose the i-400 when your parts exceed the i-200's bar capacity or machining length.

03 What control systems are available on the INTEGREX i-400?

Current-generation i-400 NEO machines run MAZATROL SmoothAi with Ai Thermal Shield for active thermal compensation. Earlier models (2012-2015) shipped with Matrix 2, and mid-generation units (2015-2020) used SmoothX. The SmoothAi is a significant upgrade for surface finish quality and thermal drift management during long multi-tasking cycles. All controls support both MAZATROL conversational and EIA/ISO G-code programming.

04 What's the difference between the i-400, i-400S, and i-400ST?

The base i-400 has a single turning spindle. The i-400S adds a second (sub) spindle for back-working operations and true done-in-one processing of both ends of a part. The i-400ST adds both a second spindle and a lower turret, maximizing simultaneous cutting capability. The S and ST variants cost $50,000-$150,000 more but dramatically reduce cycle times on parts requiring both-end machining.

05 Can the INTEGREX i-400 run unattended?

Yes. The i-400 pairs commonly with magazine bar feeders for lights-out production of bar stock parts up to 102 mm (4.0 in) diameter. Add the NC tailstock, part catcher, and chip conveyor for extended unattended operation. The SmoothAi control supports tool life management, automatic tool offset compensation, and Mazak's SMOOTH Monitor for remote machine status monitoring across shifts.

06 What maintenance does the INTEGREX i-400 require?

Standard maintenance includes spindle oil and hydraulic fluid changes, way lube system checks, coolant system upkeep, and ATC mechanism inspection. The B-axis roller cam drive should be inspected annually. Thermal compensation calibration by Mazak service is recommended every 12-18 months for shops holding tight tolerances. Budget $6,000-$12,000 per year for service and consumables on a machine this size.
