Overview

The Mazak QUICK TURN 350M is a large-frame CNC turning center with live tooling and C-axis, built for shops processing bigger parts that need cross-drilling, tapping, and flat milling without tying up a VMC. The 350M delivers the 12-inch chuck capacity and 30 kW spindle power of the QT-350 platform with milling at the lowest cost in the 350 family.

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 built-in motor design eliminates belt vibration for better surface finish on large-diameter work. The 12-position turret runs live tools at up to 4,500 RPM for cross-drilling, tapping, and milling on or near the part centerline.

Max turning diameter is 420 mm (16.54 in) over a 710 mm (27.95 in) swing. Depending on bed length, turning length ranges from 604 mm (23.8 in) on the short bed to 2,106 mm (82.92 in) on the long bed. Axis travels are 260 mm on X and 650-2,150 mm on Z depending on configuration. Rapids hit 30 m/min on X and Z.

MAZATROL SmoothG handles programming with conversational and G-code modes. The 15-inch touchscreen and 3D machining simulation make program verification straightforward before cutting metal.

The QT-350M competes with the Okuma LB3000 EX II M, Doosan Puma 3100M, and Haas ST-35. It costs more than the Haas but delivers stronger milling performance and a built-in motor spindle. Multiple bed lengths make it versatile for everything from short chucking work to long shaft jobs. New pricing typically falls between $150,000 and $240,000, with used units from the last 5-8 years trading between $60,000 and $150,000. Machine weight is approximately 6,800 kg (14,991 lb) on the standard bed. Specs sourced from Mazak Corporation published data.

Strengths & Limitations

Strengths

30 kW built-in motor spindle delivers heavy-duty roughing power for large-diameter steel, stainless, and cast iron without belt vibration
Multiple bed lengths from 23.8 to 82.92 inches of turning length make this one of the most versatile large-frame turning centers
80 mm bar capacity handles 3.15-inch bar stock for large-diameter production without spindle modifications
12-inch chuck accommodates larger chucking work while fitting in a standard production floor layout
Lower cost than the MY variant by saving the Y-axis premium while retaining full live tooling and C-axis capability
MAZATROL SmoothG with 3D simulation and conversational programming reduces setup time on short-run large-part jobs

Limitations

No Y-axis limits milling to features on or near the part centerline; off-center work requires the QT-350MY
4,500 RPM live tool speed is adequate for steel but limits productivity on aluminum milling operations
6,800 kg machine weight requires proper foundation and floor space planning, especially on long-bed variants
3,300 RPM spindle speed limits surface speed on small-diameter features within the work envelope

Best For

Shops processing large-diameter chucking work with basic cross-drilling, tapping, and flat milling requirements Oil and gas manufacturers turning valve bodies and flanges that need centerline cross-holes and tapped ports Heavy equipment shops machining hydraulic cylinders, housings, and shafts with occasional milling features Job shops that need one machine to cover short chucking through long shaft work with multiple bed length options Production environments where live tooling eliminates moving large, heavy parts to a VMC for secondary operations

Frequently Asked Questions

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

New pricing typically falls between $150,000 and $240,000 depending on bed length and options. The long-bed version costs significantly more than the short bed. Adding tailstock, steady rest, and high-pressure coolant adds to the total. Used units from the last 5-8 years trade between $60,000 and $150,000.

02 What bed lengths are available on the QT-350M?

Three bed lengths are offered: short bed with 604 mm (23.8 in), medium bed with 1,594 mm (62.72 in), and long bed with 2,106 mm (82.92 in) of turning length. Choose based on the longest parts you plan to machine.

03 What is the difference between the QT-350M and the QT-350MY?

The QT-350M has C-axis and live tooling for centerline milling. The QT-350MY adds Y-axis with 120 mm of off-center travel. The Y-axis adds approximately $30,000-$40,000 to the price. Choose the MY if your parts have off-center features.

04 Can the QT-350M handle long shaft work?

Yes. The long-bed version offers 2,106 mm (82.92 in) of turning length with tailstock support. A steady rest option is available for supporting flexible workpieces during machining.
