Mazak QRX-50

The Mazak QRX-50 is a compact twin-turret CNC turning center built around 6-inch and 8-inch chuck platforms, designed to slash cycle times through simultaneous left-and-right machining. Where a single-turret lathe runs one tool at a time, the QRX-50 runs two 12-position drum turrets independently, enabling balance cutting and simultaneous OD/ID operations that can cut cycle times by 30-50% on production parts.

The 8-inch chuck models (QRX-50, QRX-50MY) handle a maximum machining diameter of 245 mm (9.65 in) with 552 mm (21.7 in) of turning length. Bar capacity is 52 mm (2.05 in) on both main and second spindles, covering standard production bar stock for automotive and medical components. The 6-inch chuck models (QRX-50MS, QRX-50MSY) add a second spindle for complete part processing, handling rough, finish, and backwork in one cycle without operator intervention.

Both turrets use BMT45 tool holders as standard, which is a significant advantage over VDI-style tooling. BMT mounting provides better rigidity during milling operations and faster tool changes. Each turret carries 12 stations with 24-position capability, giving you plenty of tooling capacity for complex parts.

The MAZATROL SmoothG CNC manages both turrets through a dedicated dual-turret display that shows each turret position, tool data, and cycle status simultaneously. Programming two turrets working in sync requires careful attention to interference zones, but SmoothG handles collision checking automatically. The conversational programming system reduces setup time compared to writing dual-turret G-code manually.

The QRX-50 competes directly with the Doosan Puma TT1300SY, Okuma 2SP-V40, and DMG Mori NZX 1500. It slots into the $250,000-$400,000 range depending on configuration. The MSY models with Y-axis and second spindle sit at the top of that range. For shops running 1,000+ piece lots of complex turned parts, the twin-turret architecture pays for itself through cycle time reduction alone.
