Overview
The Mazak QRX-50M is a twin-turret CNC turning center with milling capability, built around an 8-inch chuck platform for production machining of mid-size parts. The M designation indicates integrated milling on the turrets, enabling drilling, tapping, and off-center machining operations without transferring parts to a separate machining center. Where the base QRX-50 SG runs pure turning tools, the QRX-50M adds driven tool stations for cross-drilling, flats, and hex features.
The dual 12-position drum turrets operate independently, enabling simultaneous left-and-right machining that cuts cycle times by 30-50% compared to single-turret lathes. Each turret carries 24-position capability with BMT45 tool holders as standard. BMT mounting provides significantly better rigidity than VDI-style tooling during milling operations, improving surface finish and extending tool life.
Maximum machining diameter is 245 mm (9.65 in) with 552 mm (21.7 in) of turning length, covering standard production bar stock sizes for automotive, hydraulic, and medical components. Bar capacity is 52 mm (2.05 in). Spindle speed reaches approximately 5,000 RPM with 18.5 kW (25 hp) of power.
The MAZATROL SmoothG CNC manages both turrets through a dedicated dual-turret display that shows each turret position, tool data, and cycle status simultaneously. Collision checking runs automatically, reducing the risk inherent in dual-turret simultaneous cutting. The QRX-50M competes directly with the Doosan Puma TT1300SY and DMG Mori NZX 1500 in the production twin-turret segment, pricing between $275,000 and $380,000.
For shops running 1,000+ piece lots of complex turned parts with milling features, the QRX-50M twin-turret architecture combined with driven tooling delivers both the cycle time reduction and the feature completion that single-turret mill-turn lathes handle sequentially.

Strengths & Limitations
Strengths
- Twin-turret simultaneous machining with milling capability cuts cycle times 30-50% while completing drilling, tapping, and milling features in the same cycle
- BMT45 tool holders on both turrets provide superior milling rigidity over VDI alternatives, critical for surface finish quality during cross-drilling and milling operations
- Dual 24-station turrets (48 tools total) accommodate complex parts needing both turning and milling tools without mid-cycle tool changes
- MAZATROL SmoothG dual-turret display simplifies programming and monitoring of simultaneous cutting operations with automatic collision checking
- 8-inch chuck with 245 mm turning diameter covers the sweet spot for automotive, hydraulic, and industrial component production
- Compact footprint relative to output capability — one QRX-50M replaces two single-turret turning centers for most production applications
Limitations
- Starting at $275K, the twin-turret milling configuration costs roughly 2x a comparable single-turret turning center with driven tools, requiring high-volume work to justify
- 8-inch chuck and 245 mm max diameter limit the QRX-50M to small-to-medium production parts — no capacity for large-diameter chuck work
- Dual-turret programming with milling adds complexity; operators need training in synchronization, interference checking, and balance cutting with driven tools
- 52 mm bar capacity is adequate but limits shops running bar stock above 2 inches to chuck-loaded work only

Frequently Asked Questions
01
New QRX-50M machines range from $275,000 to $380,000 depending on tooling configuration and options. The milling option adds approximately $25,000-$40,000 over the base QRX-50 SG. Full configurations with bar feeder, parts catcher, and high-pressure coolant push toward the higher end of the range.
02
The QRX-50M has milling capability on an 8-inch chuck platform without Y-axis or second spindle. The QRX-50MSY adds Y-axis for off-center milling and a second spindle (6-inch chuck) for back-working and complete part processing. The MSY is the most capable variant but costs $50,000-$80,000 more than the M.
03
Yes, with a magazine bar feeder and parts catcher, the QRX-50M runs unattended for extended periods. The dual turrets complete all turning and milling operations in one cycle, and the SmoothG control supports tool life management for unmanned operation. However, without a second spindle (MSY model), back-face operations still require operator intervention.
04
BMT45 tool holders are standard on both turrets. BMT provides a rigid flat-mount connection that outperforms VDI-style tooling, especially important during milling operations. Driven tool holders for BMT45 are available from Kennametal, Sandvik, EWS, and Heimatec.
