Overview

The Mazak INTEGREX i NEO is the current-generation evolution of Mazak’s flagship multi-tasking platform, covering 6 to 12-inch chuck sizes across five model families: i-100 NEO, i-200 NEO, i-250 NEO, i-350 NEO, and i-450 NEO. Each comes in base, -S, and -ST configurations. The NEO designation marks a significant redesign with a compact milling spindle head that is 17% shorter, a front-mounted tool magazine, and the MAZATROL SmoothAi control with Ai Thermal Shield.

The smaller i-100 and i-200 NEO models deliver 600 mm (23.62 in) max machining diameter with 535 mm X-axis and 210 mm Y-axis travel. The larger i-250 through i-450 NEO step up to 670 mm (26.38 in) max diameter with 695 mm X-axis and 300 mm (11.81 in) Y-axis. Chuck sizes run 6 inches (i-100), 8 inches (i-200/250), 10 inches (i-350), and 12 inches (i-450).

Milling spindle runs to 12,000 RPM with power from 12 kW (i-100) to 24 kW (32 hp) on the i-350/i-450. A 20,000 RPM option at 24 kW is available. HSK-A63 standard with Capto C6 optional. B-axis swings 240 degrees with roller cam drive and scale feedback. The front-mounted tool magazine allows tool loading from the front during operation. Standard 36 tools with 72 and 110 options.

This is the platform Mazak actively sells today. New machines range from $250,000 (i-100 NEO) to $500,000+ (loaded i-450 NEO ST). Specs sourced from Mazak published data.

Strengths & Limitations

Strengths

Covers 6 to 12-inch chuck sizes across five model families for virtually any part size without switching platforms
Compact milling head is 17% shorter, reducing interference and expanding usable machining envelope
Front-mounted tool magazine allows tool loading from the front during operation
SmoothAi with Ai Thermal Shield significantly improves long-cycle accuracy over older SmoothX and Matrix controls
12,000 RPM HSK-A63 milling spindle with up to 24 kW delivers real machining center performance
240-degree B-axis with roller cam drive provides the zero-backlash accuracy that made INTEGREX the industry standard
Each model available in base, -S, and -ST for scalable done-in-one capability

Limitations

NEO branding covers many sizes with varying specs, potentially confusing buyers comparing quotes
$250K to $500K+ puts even the smallest i-100 NEO above many small shops
Programming complexity remains high despite SmoothAi improvements
Post processors are still challenging to source for NEO machines
Smaller models (i-100/i-200 NEO) have only 210 mm Y-axis vs 300 mm on i-250+

Best For

Shops standardizing on one multi-tasking platform across multiple sizes Aerospace manufacturers needing Ai Thermal Shield for tight-tolerance long-cycle parts Job shops where front-mounted magazine and compact head improve ergonomics and setup Production environments running lights-out with SmoothAi tool life management Shops replacing older INTEGREX i-Series wanting a direct upgrade path Medical device manufacturers needing active thermal compensation for consistency

Frequently Asked Questions

01 What does an i NEO cost?

i-100 NEO starts around $250,000, i-200 NEO around $280,000, i-350/i-450 NEO $380K-$500K+. -S/-ST add $50K-$150K by model.

02 What changed from the previous i-Series?

Three major changes: milling head 17% shorter, tool magazine moved to front-mount, and SmoothAi control with Ai Thermal Shield. Mechanical platform is evolutionary; B-axis roller cam and spindle options carry forward.

03 Which model should I choose?

Match to parts: i-100 for 6 inch chuck, i-200 for 8 inch, i-250 for 8 inch with more Y-axis (300mm vs 210mm), i-350 for 10 inch, i-450 for 12 inch. -S adds back-working; -ST adds lower turret.

04 Is tooling compatible with older INTEGREX?

HSK-A63 tooling transfers directly. The compact head may have different interference profiles, so check tool assemblies for clearance. Capto C6 works with optional Capto spindle.

05 Does Ai Thermal Shield help?

Yes, particularly on 4+ hour cycles. Multiple temperature sensors actively compensate for thermal growth in real time. Measurable improvements over older SmoothX machines, especially in shops without climate control.
