Overview

The Mazak INTEGREX i-250H is a mid-size multi-tasking machine built around the proven INTEGREX i-H platform, featuring a horizontal spindle configuration with a second turning spindle for done-in-one processing of complex parts. The H designation signals a higher-capacity frame compared to the standard i-200 series, accommodating larger work envelopes while maintaining the precision Mazak is known for in this class.

The main turning spindle delivers 26 kW (35 hp) at 4,000 RPM through a 10-inch chuck with 80 mm (3.15 in) bar capacity, giving shops the power to rough medium-diameter steel and stainless bar stock aggressively. The second turning spindle runs at 4,000 RPM with 18.5 kW (25 hp) for balanced back-end operations. The milling spindle delivers 18.5 kW (25 hp) at 12,000 RPM through a Capto C6 tooling interface, with a 20,000 RPM high-speed option for aluminum-intensive work.

The B-axis provides 240 degrees of travel (-30 to +210 degrees) with 0.0001-degree indexing resolution on a roller cam drive for zero-backlash positioning. Y-axis travel of 230 mm (9.06 in) enables off-center milling, drilling, and tapping. Axis travels span 615 mm (24.2 in) on X and 1,100 mm (43.3 in) on Z, giving a maximum machining diameter of 660 mm (26 in) and maximum machining length of 1,100 mm. Rapids hit 38 m/min on X and Z axes.

The standard 36-tool ATC expands to 72 or 110 positions. Current production ships with the MAZATROL SmoothAi CNC featuring Ai Thermal Shield and Smooth Monitor for remote operation monitoring. The machine weighs approximately 13,000 kg (28,660 lb) with a footprint of roughly 5.0 x 2.6 meters. Direct competitors include the DMG Mori NTX 2000, Okuma MULTUS B300II, and Nakamura-Tome Super NTJX. New machines price between $380,000 and $550,000, with used units from 2015-2021 trading between $170,000 and $350,000.

Strengths & Limitations

Strengths

Larger 660 mm max machining diameter and 80 mm bar capacity step up from the i-200 series, handling medium-diameter shaft work and chucked parts that smaller INTEGREX models cannot accommodate
Dual turning spindles enable done-in-one processing of both part ends, eliminating refixturing and the tolerance stack-up that comes with multiple setups
12,000 RPM Capto C6 milling spindle with 18.5 kW provides genuine machining center performance for complex milling, drilling, and tapping within the turning cycle
240-degree B-axis with roller cam drive and 0.0001-degree resolution delivers zero-backlash 5-axis contouring for aerospace and medical geometries
MAZATROL SmoothAi control with Ai Thermal Shield actively compensates for thermal drift during long multi-tasking cycles, maintaining tight tolerances over extended runs
Mazak's North American manufacturing in Florence, KY ensures strong parts availability and factory-trained service technicians across the continent

Limitations

13,000 kg machine weight and 5.0 x 2.6 meter footprint require substantial floor space and foundation considerations compared to smaller i-200 series machines
Starting price near $380K is a significant capital investment that requires consistent multi-tasking utilization to justify over separate turning and milling centers
Programming complexity for simultaneous dual-spindle and B-axis operations demands experienced multi-tasking programmers and custom post processors
Second spindle power at 18.5 kW is adequate for most back-end work but may limit aggressive roughing on exotic alloys during back-working operations
Periodic B-axis calibration and spindle alignment checks add to maintenance costs, typically requiring Mazak service at $250+/hour every 12-18 months

Best For

Aerospace job shops machining turbine shafts, structural components, and landing gear parts requiring turning, milling, and drilling on both ends in a single setup Oil and gas manufacturers producing downhole tools, valve bodies, and pump components from stainless and Inconel where done-in-one processing eliminates datum shifts Medical device producers machining orthopedic implants and surgical instruments from titanium and cobalt-chrome where multi-tasking reduces handling contamination risk Defense contractors producing ordnance and precision guidance components where maintaining datum relationships across all features is critical for part accuracy Production shops running bar-fed operations on medium-diameter parts up to 80 mm that require complete front-and-back machining in a single cycle

Frequently Asked Questions

01 What does a new Mazak INTEGREX i-250H cost?

Base i-250H configurations start around $380,000. Production-ready setups with high-speed milling spindle, through-spindle coolant, expanded tool magazine (72 or 110 tools), and bar feeder interface typically run $450,000-$550,000. Used i-250H machines from 2015-2021 trade between $170,000 and $350,000 depending on hours, configuration, and control generation.

02 What is the difference between the INTEGREX i-250H and the i-200S?

The i-250H is a larger-frame machine with 660 mm max machining diameter (vs 500 mm), 80 mm bar capacity (vs 65 mm), and a more powerful 26 kW main spindle (vs 22 kW). The H designation also indicates longer axis travels. The i-200S is better suited for smaller-diameter precision parts, while the i-250H handles medium-size shaft work and larger chucked components.

03 Can the INTEGREX i-250H run lights-out production?

Yes. Combined with a magazine bar feeder, part catcher, chip conveyor, and the SmoothAi tool life management system, the i-250H supports extended unattended operation. The dual spindle design means complete parts drop finished without manual intervention. Most shops report 6-12 hours of unattended runtime depending on part complexity and material.

04 How does the i-250H compare to the DMG Mori NTX 2000?

Both are mid-size dual-spindle multi-tasking machines. The i-250H offers a larger max machining diameter and Mazak's broader North American service network. The NTX 2000 features the CELOS control ecosystem and compactMASTER direct-drive milling spindle. Pricing is comparable. The choice typically comes down to existing brand standardization and local dealer support quality.
