Overview
The Mazak INTEGREX i-350 NEO is the current-generation 10-inch-chuck multi-tasking machine in the INTEGREX i NEO lineup, positioned between the 8-inch i-250 NEO and the 12-inch i-450 NEO. The i-350 NEO combines a large work envelope with the NEO platform's compact milling head and front-mounted tool magazine, making it the natural choice for medium-to-large shaft work, flanges, and structural components that demand full 5-axis multi-tasking capability.
The main turning spindle delivers 30 kW (40 hp) at 3,600 RPM through a 10-inch chuck with 102 mm (4.02 in) bar capacity, supporting aggressive roughing on large-diameter bar stock in steel, stainless, and titanium. The NEO compact milling spindle head, 17% shorter than the previous generation, runs at 12,000 RPM with 24 kW (32 hp) through HSK-A63 tooling. A 20,000 RPM high-speed option is available for aluminum and composite finishing operations.
Axis travels span 695 mm (27.4 in) on X and 300 mm (11.81 in) on Y. Three bed lengths provide maximum machining lengths of 1,011 mm (39.80 in), 1,519 mm (59.80 in), or 2,501 mm (98.43 in). Maximum machining diameter is 670 mm (26.38 in). The B-axis provides 240 degrees (-30 to +210) with roller cam drive and 0.0001-degree resolution. The front-mounted 36-tool magazine expands to 72 or 110 positions.
The MAZATROL SmoothAi control with Ai Thermal Shield provides active thermal compensation. Available in base (with tailstock), -S (sub spindle), and -ST (sub spindle plus lower turret) configurations. Machine weight is approximately 16,000 kg (35,274 lb). New machines price between $380,000 and $550,000.

Strengths & Limitations
Strengths
- 10-inch chuck with 102 mm bar capacity handles medium-to-large diameter shaft work that exceeds the 8-inch i-250 NEO's 80 mm limit
- Three bed length options from 39.8 to 98.4 inches accommodate a wide range of part lengths from compact housings to long shafts
- NEO compact milling head is 17% shorter than previous generation, expanding usable envelope and reducing interference during complex angle approaches
- 24 kW HSK-A63 milling spindle delivers genuine machining center performance for heavy milling and drilling within the multi-tasking cycle
- Available in base, -S, and -ST configurations allowing shops to match investment to production needs
- Front-mounted tool magazine enables tool loading during operation, reducing non-cutting time on high-mix runs
Limitations
- 3,600 RPM main spindle is slower than the i-250 NEO's 4,000 RPM, limiting high-speed turning on small-diameter aluminum
- 16,000 kg machine weight and substantial footprint require engineered foundations and crane capacity for installation
- Starting price near $380K for the base model requires consistent high-value work to justify
- Longest bed option at 98.4 inches significantly increases floor space requirements and cost

Frequently Asked Questions
01
Base starts around $380,000. -S adds $60K-$100K, -ST adds another $40K-$60K. Fully optioned ST with long bed runs $500K-$550K. Used previous-gen i-350 machines from 2015-2022 trade $200K-$400K.
02
NEO brings compact milling head (17% shorter), front-mounted tool magazine, and SmoothAi with Ai Thermal Shield. Core work envelope and spindle specs are similar. NEO commands 10-15% premium.
03
Three options: 1,011 mm (39.80 in), 1,519 mm (59.80 in), and 2,501 mm (98.43 in). Most shops choose the middle bed. Each step up adds $25K-$40K.
04
Steps up from 8-inch to 10-inch chuck and 80 mm to 102 mm bar with more powerful 30 kW vs 26 kW main spindle. Y-axis and milling spindle specs are identical. Choose i-350 NEO for parts exceeding 80 mm bar diameter.
