Overview
The Mazak Quick Turn 250MSY is the fully loaded variant of the Quick Turn 250 platform, combining a sub-spindle, Y-axis, and live milling in one compact turning center. It's Mazak's go-to MSY-class machine for shops that want done-in-one capability without stepping up to the INTEGREX line. Mazak featured the QT-250MSY at IMTS 2024 with the GR100 gantry robot, pushing it hard as an automated production cell.
The main spindle sits behind a 10-inch chuck on an integral motor putting out 26 kW (35 hp) at 4,000 RPM with 465 Nm (343 ft-lbs) of torque. That's enough grunt for aggressive roughing in 4140, stainless, and Inconel. On the back end, the 6-inch sub-spindle runs 11 kW (15 hp) at 6,000 RPM for secondary ops and synchronized part transfer. Handoff between spindles is automatic, keeping cycle times tight on production runs.
Milling comes from a direct-drive rotary tool spindle rated at 8 kW (10 hp) and 6,000 RPM. No belts to wear out or retension. The 12-position turret takes VDI or bolt-on tooling for cross-drilling, tapping, hex milling, keyway cutting, and off-center work. Y-axis travel of 102 mm (4.0 in) lets you reach features above and below centerline without fixturing workarounds.
Capacity numbers: 380 mm (14.75 in) max turning diameter, 541 mm (21.275 in) turning length, and 65 mm (2.56 in) standard bar capacity through the spindle bore. Max swing over the bed is 675 mm (26.5 in). The machine tips the scales around 5,670 kg (12,500 lb), providing solid mass for interrupted milling cuts.
The SmoothG control handles MAZATROL conversational and EIA/ISO programming. Conversational is quick for simple turned parts and short runs. Most shops running complex mill-turn geometry post from Mastercam or Fusion 360. The control also supports tool life management, part tracking, and Ethernet connectivity.
Direct competitors include the Haas ST-20Y, Okuma LB3000 EX II MY, and DMG Mori NLX 2500/700. The Mazak costs more than the Haas but delivers a stronger milling spindle and more capable sub-spindle. Against the Okuma and DMG Mori, specs are close. The decision usually comes down to dealer support and which control platform your operators already know.

Strengths & Limitations
Strengths
- Sub-spindle and Y-axis make it a true done-in-one machine, cutting secondary setups on complex turned-and-milled parts
- 35 hp main spindle with 465 Nm of torque eats through steel and stainless without bogging down during heavy roughing
- Direct-drive milling at 8 kW (10 hp) and 6,000 RPM eliminates belt maintenance and delivers cleaner surface finishes on milled features than belt-driven competitors
- 6,000 RPM sub-spindle with synchronous transfer keeps cycle times low and enables lights-out production with a bar feeder
- MAZATROL SmoothG conversational programming cuts setup time on short-run jobs compared to straight G-code on Fanuc-based competitors
- GR100 gantry robot integration is pre-engineered by Mazak, simplifying automation without third-party cell builders
- Mazak's direct sales and service network across North America means faster response times than some competitors relying on distributor networks
Limitations
- Starting around $180K new, it's a big step up from simpler turning centers like the Haas ST-20Y at half the price
- MAZATROL control is proprietary; Fanuc-trained operators need 1-2 weeks to get comfortable with the interface and conversational workflow
- 65 mm standard bar capacity is tighter than the 76 mm some competitors offer, limiting bar stock diameter without a spindle liner upgrade
- Milling spindle at 8 kW won't replace a dedicated VMC for heavy pocketing, large face mills, or deep 3D surfacing
- Mazak parts and service pricing runs higher than Haas or some domestic alternatives

Frequently Asked Questions
01
New pricing typically falls between $180,000 and $280,000 depending on options. Bar feeder integration, high-pressure coolant, extra live tool stations, and the GR100 gantry robot all push the price higher. Used QT-250MSYs from 2018-2022 trade in the $100,000-$160,000 range depending on hours and condition.
02
The M has live tooling and C-axis but no sub-spindle or Y-axis. The MSY adds a 6-inch sub-spindle for automatic part transfer and secondary operations, plus 102 mm of Y-axis travel for off-center milling. The MSY costs more but eliminates moving parts to a second machine for backworking.
03
Yes. With 65 mm standard bar capacity and a bar feeder interface built in, it handles most common production bar stock. The sub-spindle enables automatic cutoff and part transfer. Many shops run the QT-250MSY lights-out with a magazine bar feeder for unattended shifts.
04
Both are capable MSY-class turning centers in a similar price range. The Mazak offers MAZATROL conversational programming, which is faster for simple parts. The DMG Mori runs CELOS with a Fanuc or Siemens control underneath. Spindle specs are comparable. It usually comes down to dealer support in your area and which control your operators already know.
05
Cross-drilling, tapping, flat milling, hex milling, keyway cutting, and off-center features are all fair game. The 8 kW milling spindle and Y-axis handle most secondary operations that would otherwise go to a VMC. For heavy pocketing, big face mills, or complex 3D surfacing, you'll still want a dedicated mill or a full mill-turn like the INTEGREX.
06
There's a learning curve, but it's not as steep as people fear. The SmoothG supports both MAZATROL conversational and standard EIA/ISO G-code. Most Fanuc operators can run EIA programs on day one. Learning MAZATROL conversational takes about 1-2 weeks of hands-on time. Mazak also offers training classes at their Florence, KY facility.
