Overview

The Mazak INTEGREX i-250 NEO is the largest of the compact-to-mid-range NEO-generation INTEGREX machines, stepping up from the i-200 NEO with a larger machining diameter, significantly longer machining length options, and more Y-axis travel. The i-250 NEO bridges the gap between the compact i-200 and the heavy-duty i-350.

The i-250 NEO runs an 8-inch chuck with a maximum machining diameter of 670 mm (26.38 in) and machining lengths of 1,011 mm (39.80 in) or 1,519 mm (59.80 in) depending on bed configuration. The Y-axis provides 300 mm (11.81 in) of travel, significantly more than the i-200 NEO at 210 mm.

The main turning spindle delivers 22 kW (30 hp) at 5,000 RPM with 65 mm bar capacity. The milling spindle operates at 12,000 RPM standard (20,000 RPM optional) through HSK-A63 with 18.5 kW (25 hp). The B-axis swings 240 degrees (-30 to +210 degrees) with roller cam drive and 0.0001-degree resolution.

The NEO generation brings MAZATROL SmoothAi CNC with Ai Thermal Shield, redesigned compact milling head, and front-mounted tool magazine. The standard 36-tool ATC expands to 72 or 110 tools. Available in S and ST variants.

Competes with the DMG Mori CTX beta 2000 TC, Okuma Multus B300II, and Nakamura-Tome NTX 2500. New machines start around $330,000 with production-ready configs running $400,000-$520,000.

Strengths & Limitations

Strengths

300 mm Y-axis travel provides 43% more off-center milling reach than the i-200 NEO (210 mm)
670 mm machining diameter and up to 1,519 mm length accommodate medium-to-large parts beyond the i-200 NEO envelope
HSK-A63 milling spindle at 18.5 kW delivers full machining center performance with the larger Y-axis envelope
Available in S and ST variants for done-in-one processing and simultaneous multi-tasking
SmoothAi with Ai Thermal Shield is especially valuable on longer-bed configurations
Same 8-inch chuck and 65 mm bar capacity provides familiar tooling compatibility for shops upgrading

Limitations

Larger footprint than the i-200 NEO, especially with the 1,519 mm long-bed option
Starting at $330K and reaching $520K+ for ST, requires parts that genuinely need the extra envelope
5,000 RPM main turning spindle limits surface speed on small-diameter aluminum work
11,000 kg machine weight requires solid foundation preparation

Best For

Aerospace shops machining medium-to-large structural components exceeding the i-200 NEO 590 mm length Energy sector manufacturers producing valve bodies, pump components, and turbine parts Job shops handling diverse medium-to-large parts where 300 mm Y-axis enables features smaller machines cannot reach Production environments running long shafts up to 1,519 mm with full 5-axis milling Shops stepping up from the i-200 NEO without jumping to the i-350 NEO

Frequently Asked Questions

01 i-200 NEO vs i-250 NEO?

i-250 NEO offers larger diameter (670 vs 600 mm), longer length (up to 1,519 mm vs 590 mm), and more Y-axis (300 vs 210 mm). Both use 8-inch chucks. i-250 NEO costs $30,000-$70,000 more.

02 What does a new i-250 NEO cost?

Base starts around $330,000. S variants run $400,000-$450,000. ST variants run $460,000-$520,000.

03 Is it available with sub-spindle?

Yes. The i-250S NEO adds a sub-spindle. The i-250ST NEO adds both sub-spindle and lower turret.

04 i-250 NEO vs previous i-250H?

The NEO replaces the i-250H with SmoothAi, Ai Thermal Shield, compact milling head, and front-mounted magazine. Similar work envelope but better thermal stability.
