Overview
The Mazak QRX-50MSY is the most capable variant in the QRX-50 twin-turret turning center lineup, combining dual turrets, Y-axis milling capability, and a second spindle for complete part processing in a single machine cycle. The MSY designation means Milling + Sub-spindle + Y-axis — every axis and feature option available on the QRX-50 platform, built around a 6-inch chuck configuration.
The dual 12-position drum turrets operate independently with BMT45 tool holders as standard, enabling simultaneous left-and-right machining that cuts cycle times by 30-50% compared to single-turret configurations. Each turret carries 24-position capability. The Y-axis adds off-center milling capability for features like flats, keyways, and eccentric holes that cannot be produced with pure C-axis interpolation.
The second spindle enables automatic part transfer from the main spindle for back-face machining — drilling, boring, tapping, and turning the back end of the workpiece without operator intervention. Combined with a bar feeder and parts catcher, the QRX-50MSY can run complete parts lights-out: rough, finish, mill, and backwork all in one unattended cycle.
Bar capacity is 52 mm (2.05 in) on both main and second spindles. Maximum machining diameter is 245 mm (9.65 in) with 900 mm (35.43 in) of machining length. Spindle speed reaches approximately 5,000 RPM with 18.5 kW (25 hp). The MAZATROL SmoothG CNC manages all axes of turret motion plus spindle synchronization through dedicated dual-turret programming screens.
The QRX-50MSY competes directly with the Doosan Puma TT1300SYY, Okuma 2SP-V40, and DMG Mori NZX 1500/800SY2. New machines price between $350,000 and $450,000. For shops running complex production parts needing both-end machining with milling, the MSY pays for itself through the elimination of secondary operations and operator touches.

Strengths & Limitations
Strengths
- Complete part processing: dual turrets + Y-axis milling + sub-spindle produces finished parts from bar stock in a single unattended cycle with no secondary operations
- Twin-turret simultaneous machining cuts cycle times 30-50% while Y-axis milling handles off-center features that C-axis interpolation alone cannot produce
- BMT45 tool holders on both turrets provide the rigidity needed for accurate Y-axis milling, cross-drilling, and tapping operations on production parts
- 52 mm bar capacity on both spindles covers standard production bar stock sizes for automotive, medical, and hydraulic component manufacturing
- 48-tool total capacity (24 per turret) accommodates complex parts with many different turning, drilling, and milling tools without mid-cycle changes
- MAZATROL SmoothG with automatic collision checking manages the complex synchronization between dual turrets, dual spindles, and Y-axis milling
Limitations
- At $350K-$450K, the full MSY configuration costs roughly 2.5x a single-turret sub-spindle lathe, requiring consistently high-value complex parts to justify the investment
- Programming dual turrets with Y-axis milling and sub-spindle synchronization is significantly more complex than standard turning — expect 2-4 weeks of operator training
- 6-inch chuck on both spindles limits part diameter compared to the 8-inch chuck models (QRX-50 SG, QRX-50MY SG), restricting work to smaller-diameter bar and chuck parts
- More mechanical complexity means more potential maintenance points: two turrets, two spindles, Y-axis drive, and bar feeder interface all require regular attention

Frequently Asked Questions
01
New QRX-50MSY machines range from $350,000 to $450,000 depending on tooling, bar feeder, and options. This is the top-of-line QRX-50 configuration. Adding a magazine bar feeder and parts catcher for lights-out operation adds $30,000-$50,000 to the base machine price.
02
The SG designation indicates the latest generation design with improved chip flow and updated SmoothG control features. Functionally, both offer the same MSY capability: Milling, Sub-spindle, and Y-axis. The SG models represent the current production iteration.
03
For parts within its envelope (245 mm diameter, 52 mm bar), yes. The QRX-50MSY handles turning, milling, drilling, tapping, and back-face operations in one cycle. The Y-axis enables true off-center milling for flats, keyways, and hex features. However, it is not a replacement for a full VMC on large, flat milled parts or heavy 3-axis milling work.
04
Different architectures for different needs. The INTEGREX i-100S is a 5-axis mill-turn with B-axis milling spindle — better for complex angular milling and contouring. The QRX-50MSY uses twin turrets with driven tools — better for high-volume production where simultaneous cutting from two turrets maximizes throughput. The INTEGREX handles complexity; the QRX handles volume.
