Overview

The Mazak HQR-250MSY is the largest model in the HQR twin-turret, twin-spindle turning center family, featuring a 10-inch chuck for maximum workpiece capacity. The HQR-250MSY delivers the full HQR production architecture scaled up for larger parts, combining simultaneous dual-turret machining with complete done-in-one processing capability.

The HQR-250MSY runs a 254 mm (10 in) main chuck with a maximum turning diameter of 343 mm (13.5 in) and maximum turning length of 861 mm (33.9 in), extending to 1,326 mm (52.2 in) in the long-bed variant. The main spindle delivers 26 kW (35 hp) at up to 3,500 RPM through an A2-8 spindle nose with a 91 mm (3.58 in) spindle bore. Bar capacity is 80 mm (3.15 in), accommodating 3-inch bar stock.

The twin-turret configuration provides simultaneous machining from two directions. Both turrets feature BMT live tooling and C-axis capability, with Y-axis on the upper turret for off-center milling operations. The 10-inch dual spindles with W-axis sub-spindle travel handle automatic part transfer for complete front-and-back processing of larger workpieces.

MAZATROL SmoothG manages the multi-channel programming with collision avoidance for safe dual-turret operations. The 91 mm spindle bore and 80 mm bar capacity make the HQR-250MSY the preferred choice for production bar feeding of larger diameter stock through the twin-turret platform.

The HQR-250MSY competes with the Nakamura-Tome WTW-250, Index G300, DMG Mori NZX 2500, and Okuma MULTUS B300II. It is the flagship of the HQR 2-turret lineup, offering the largest capacity with the same simultaneous machining advantage. For shops running high-volume production of larger complex parts that justify the investment, the HQR-250MSY maximizes throughput and minimizes per-part cost.

Strengths & Limitations

Strengths

10-inch chuck with 91 mm spindle bore handles the largest parts in the HQR lineup
Twin-turret simultaneous cutting delivers 30-50% cycle time reduction on production lots
26 kW spindle power supports aggressive stock removal on larger workpieces
80 mm bar capacity enables production bar feeding of 3-inch stock through twin turrets
Long-bed option extends turning length to 52.2 inches for shaft production
MAZATROL SmoothG with collision avoidance for safe dual-turret operations

Limitations

Starting at $320K, this is a significant investment requiring high-volume production justification
9,000 kg machine weight demands substantial floor space and foundation considerations
Multi-channel dual-turret programming requires experienced staff or advanced CAM software
3,500 RPM max spindle speed limits surface speed on smaller-diameter features

Best For

High-volume production of complex 10-inch chuck parts requiring simultaneous machining Automotive and heavy equipment component manufacturing at maximum throughput Aerospace production of medium-to-large turned parts with complete done-in-one processing Contract manufacturers running large campaigns on complex parts from 3-inch bar stock Shops needing the largest twin-turret platform in the HQR family

Frequently Asked Questions

01 What does a new Mazak HQR-250MSY cost?

New pricing runs $320,000-$500,000 depending on bed length, tooling configuration, and options. It is the most expensive model in the HQR 2-turret lineup.

02 HQR-250MSY vs HQR NEO?

The HQR NEO adds a third turret for even more simultaneous operations. The HQR-250MSY has 2 turrets at a lower price point. Both are available in 10-inch chuck size.

03 What bar stock can I run through the HQR-250MSY?

Up to 80 mm (3.15 in) diameter bar stock through the 91 mm spindle bore. Compatible with LNS, Iemca, and FMB bar feeders.

04 Is the HQR-250MSY suitable for job shop work?

Generally no. The dual-turret complexity and setup time favor production runs of 500+ pieces. Job shops are better served by single-turret Quick Turn or QT-Ez machines.
