Overview

The Mazak QUICK TURN 350MSY is the fully loaded variant of the QT-350 platform, combining a 12-inch chuck, 30 kW spindle, sub-spindle, Y-axis, and live tooling into a large-frame done-in-one turning center. For shops machining bigger parts with complex features on both ends, the QT-350MSY eliminates the need for multiple setups and machines.

The main spindle delivers 30 kW (40 hp) at 3,300 RPM through an A2-8 spindle nose with 80 mm (3.15 in) bar capacity. The sub-spindle runs 15 kW (20 hp) at 4,500 RPM through a 10-inch chuck for automatic part transfer and backworking. The Y-axis provides 120 mm of off-center travel for milling features above and below centerline including bolt patterns, eccentric holes, and angled flats.

The 12-position turret accepts live tools running at 4,500 RPM with full C-axis indexing. Max turning diameter is 420 mm (16.54 in) over a 710 mm (27.95 in) swing, with 604 mm (23.8 in) of turning length on the standard bed. Axis travels are 260 mm on X, 120 mm on Y, and 650 mm on Z. Rapids hit 30 m/min on X and Z.

MAZATROL SmoothG handles programming with built-in synchronization, Y-axis milling cycles, and 3D simulation on a 15-inch touchscreen. The control manages the coordination between main spindle, sub-spindle, Y-axis, and live tools through conversational cycles that simplify what would otherwise be extremely complex programming.

The QT-350MSY competes with the Okuma LB3000 EX II MSY, Doosan Puma 3100MSY, and DMG Mori NLX 3000 MSY. It represents the maximum capability in the Quick Turn 350 family. New pricing typically falls between $250,000 and $380,000, with used units from recent years trading between $110,000 and $220,000. Machine weight is approximately 8,500 kg (18,739 lb).

Strengths & Limitations

Strengths

Full MSY configuration on a 12-inch chuck platform provides maximum done-in-one capability for large parts with complex features on both ends
30 kW built-in motor spindle with 120 mm Y-axis travel enables heavy roughing and off-center milling in a single setup
15 kW sub-spindle with 10-inch chuck handles substantial backworking operations on large-diameter parts
Multiple bed length options offer versatility from short chucking work to longer shaft machining applications
MAZATROL SmoothG with built-in synchronization and Y-axis cycles simplifies complex multi-axis programming
80 mm bar capacity with sub-spindle cutoff enables automated production of large-diameter bar stock parts

Limitations

Starting around $250K new, the full MSY configuration represents a major capital investment
8,500 kg machine weight requires reinforced foundation and substantial floor space allocation
4,500 RPM live tool speed is moderate; not suited for high-speed aluminum milling operations
Programming complexity of synchronized MSY operations requires skilled operators or dedicated programmers

Best For

Oil and gas manufacturers producing large flanges, valve bodies, and couplings with off-center features on both faces Aerospace subcontractors machining large structural components with Y-axis milling and backworking in one setup Heavy equipment manufacturers consolidating multi-machine operations on large hydraulic and powertrain components Production shops running large two-sided parts with bolt patterns, eccentric ports, and milled features Shops seeking the maximum Quick Turn 350 capability before stepping up to INTEGREX multi-tasking machines

Frequently Asked Questions

01 What does a new Mazak QUICK TURN 350MSY cost?

New pricing typically falls between $250,000 and $380,000 depending on bed length and options. Adding bar feeder, high-pressure coolant, steady rest, and automation pushes the total higher. Used units from recent years trade between $110,000 and $220,000.

02 How does the QT-350MSY compare to the Mazak INTEGREX?

The QT-350MSY is a turning center with milling capability. The INTEGREX is a true multi-tasking machine with a dedicated B-axis milling spindle that can do 5-axis simultaneous work. The INTEGREX handles more complex milling but costs significantly more. The QT-350MSY covers 80% of mill-turn applications at a lower price.

03 What is the Y-axis travel on the QT-350MSY?

The QT-350MSY provides 120 mm of Y-axis travel, generous for a machine in this size class. This enables off-center milling operations like bolt patterns, eccentric holes, and features positioned away from the part centerline.

04 Can the QT-350MSY run lights-out?

Yes, with proper setup. A bar feeder handles material loading, the sub-spindle manages cutoff and transfer, and the parts catcher collects finished components. Tool life management in SmoothG monitors wear. Many shops run unattended shifts on the QT-350MSY for production work.
