Overview

The Mazak QUICK TURN 250MS pairs the proven 10-inch chuck QT-250 platform with a sub-spindle and live tooling for done-in-one part processing without Y-axis. The MS configuration targets production shops that need automatic part transfer and backworking but keep milling features on or near centerline, saving the Y-axis premium found on the MSY variant.

The main spindle delivers 18.5 kW (25 hp) at 4,000 RPM through an A2-8 spindle nose with 65 mm (2.56 in) bar capacity. The sub-spindle runs 11 kW (15 hp) at 6,000 RPM through a 6-inch chuck, providing automatic part pickup, cutoff, and backworking operations including face finishing, chamfering, ID boring, and tapping.

The 12-position turret accepts live tools running at 5,000 RPM with C-axis indexing for cross-drilling, tapping, and flat milling on the part centerline. Max turning diameter is 380 mm (14.96 in) over a 675 mm (26.5 in) swing, with 541 mm (21.3 in) of turning length. Axis travels are 234 mm on X, 625 mm on Z, and approximately 585 mm on the W-axis for sub-spindle positioning. Rapids hit 30 m/min on X and Z.

MAZATROL SmoothG handles programming with built-in synchronization cycles for coordinated main and sub-spindle operations. The control simplifies what would otherwise be complex sync coding for part transfer, simultaneous cutting, and sequential backworking operations.

The QT-250MS competes with the Okuma LB3000 EX II MS, Doosan Puma 2600MS, and DMG Mori NLX 2500 with sub-spindle. New pricing typically falls between $155,000 and $230,000. Used units from the last 5-8 years trade between $65,000 and $130,000. Machine weight is approximately 5,400 kg (11,905 lb). Specs sourced from Mazak Corporation published data.

Strengths & Limitations

Strengths

Sub-spindle with automatic part transfer enables done-in-one processing, eliminating rechucking and secondary operations for two-sided parts
Lower cost than the QT-250MSY by omitting Y-axis, saving $20,000-$40,000 for shops that keep milling features on centerline
18.5 kW main spindle with 10-inch chuck handles mid-size production parts in steel, stainless, and cast iron
BMT live tooling at 5,000 RPM provides solid milling rigidity for cross-drilling, tapping, and centerline flat milling
MAZATROL SmoothG with built-in synchronization cycles simplifies programming of coordinated dual-spindle operations
65 mm bar capacity with sub-spindle cutoff and transfer enables fully automated bar-fed production

Limitations

No Y-axis limits milling to features on or near the part centerline; off-center work requires the QT-250MSY
Starting around $155K new, the sub-spindle adds substantial cost over the base QT-250M
Programming synchronized dual-spindle operations has a steeper learning curve than standard single-spindle turning
5,400 kg machine weight and larger footprint require more floor space and foundation consideration than single-spindle variants

Best For

Production shops running two-sided parts where milling features stay on or near centerline and backworking is essential Automotive and hydraulic component manufacturers producing shafts, fittings, and connectors with both-end machining requirements Bar-fed production environments where automatic cutoff and sub-spindle transfer maximize spindle utilization Contract manufacturers reducing WIP and handling by consolidating two-operation lathe work into a single setup Shops that need sub-spindle done-in-one capability but can save the Y-axis premium for centerline-only milling work

Frequently Asked Questions

01 What does a new Mazak QUICK TURN 250MS cost?

New pricing typically falls between $155,000 and $230,000 depending on options. Adding high-pressure coolant, bar feeder, parts catcher, and additional tooling pushes the price higher. Used units from 2015-2022 trade between $65,000 and $130,000.

02 What is the difference between the QT-250MS and the QT-250MSY?

Both have milling and a sub-spindle. The MSY adds 102 mm of Y-axis off-center travel for milling features above and below the part centerline. The Y-axis adds approximately $20,000-$40,000 to the price. Choose the MS if your parts only need centerline milling.

03 Can the QT-250MS run unattended?

Yes. With a bar feeder, parts catcher, and the sub-spindle handling automatic cutoff and transfer, the QT-250MS can run lights-out through a full bar of material. Tool life management in the SmoothG control adds another layer of unattended reliability.

04 How does the QT-250MS compare to the Okuma LB3000 EX II MS?

Both are solid 10-inch sub-spindle turning centers. The Mazak offers MAZATROL conversational programming while the Okuma runs its OSP control. Spindle specs are comparable. The choice typically comes down to control preference, dealer proximity, and existing shop infrastructure.
