Overview

The Mazak INTEGREX i-350S NEO is the dual-spindle variant of the current-generation i-350 NEO platform, adding a fully programmable sub spindle for complete done-in-one processing of medium-to-large parts. The combination of 10-inch main chuck, 102 mm bar capacity, and automatic part transfer makes this one of the most capable production multi-tasking machines in the NEO lineup.

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. The sub spindle provides 22 kW (30 hp) at 3,600 RPM with an 8-inch chuck for back-working and part transfer operations. The NEO compact milling spindle head runs at 12,000 RPM with 24 kW (32 hp) through HSK-A63 tooling, with a 20,000 RPM high-speed option available.

Axis travels span 695 mm (27.4 in) on X, 300 mm (11.81 in) on Y, with machining lengths of 1,011 mm (39.80 in) or 1,519 mm (59.80 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 indexing resolution.

The front-mounted 36-tool magazine expands to 72 or 110 positions. SmoothAi with Ai Thermal Shield. Machine weight approximately 19,000 kg (41,888 lb). New machines 00,000-00,000. Competitors: DMG Mori NTX 2500 and Okuma MULTUS U4000.

Strengths & Limitations

Strengths

Dual-spindle with 22 kW sub spindle enables true done-in-one processing with heavy back-working capability
10-inch main chuck and 102 mm bar capacity handle large shaft work in steel, stainless, and titanium
NEO compact milling head 17% shorter expands usable envelope during complex angle approaches
24 kW HSK-A63 milling spindle delivers genuine machining center performance
300 mm Y-axis accommodates larger off-center features on substantial workpieces
SmoothAi with Ai Thermal Shield maintains accuracy during long dual-spindle production cycles

Limitations

Starting near $500K requires consistent dual-end large-part production to justify over base i-350 NEO
19,000 kg requires engineered foundations adding $15K-$30K to installation
3,600 RPM main spindle limits high-speed turning on small-diameter aluminum
Dual-spindle programming complexity requires 4-6 months ramp-up

Best For

Aerospace manufacturers producing large turbine shafts and landing gear requiring both-end processing Oil and gas shops machining downhole tools and valve components from Inconel and duplex stainless Power generation facilities producing turbine rotors and compressor components with both-end features Production environments running bar-fed lights-out on medium-to-large bar stock Shops upgrading from previous-gen i-350S wanting NEO compact head and SmoothAi improvements

Frequently Asked Questions

01 i-350S NEO cost?

Base starts around $500,000. Production-ready with high-speed milling, HPC, expanded magazine runs $600K-$700K. Previous-gen i-350S from 2015-2021 trades $220K-$450K.

02 NEO vs previous-gen i-350S?

NEO brings compact milling head (17% shorter), front-mounted magazine, and SmoothAi with Ai Thermal Shield. 10-15% premium for improved ergonomics and thermal management.

03 Inconel and titanium?

Yes. 30 kW main spindle handles superalloys. High-pressure coolant (70-100 bar) recommended for Inconel. SmoothAi adaptive feed control adjusts based on spindle load.

04 Automation options?

Magazine bar feeders up to 102 mm, gantry loaders, robotic cells. SMOOTH Monitor for remote status. Part catcher and tool life management for lights-out.
