Overview

The Mazak HQR-250 NEO is the 10-inch chuck variant of the HQR NEO platform, Mazak's flagship 3-turret, 2-spindle CNC turning center built for maximum production throughput on medium-to-large diameter parts. The HQR-250 NEO delivers the same 4-axis simultaneous machining capability as the HQR-200 NEO but with larger spindle bores and chuck capacity for handling bigger workpieces.

The HQR-250 NEO runs dual 10-inch (254 mm) chucks with a maximum machining diameter of 320 mm (12.6 in) and 860 mm (33.86 in) of turning length. The main spindle bore measures 91 mm (3.58 in) with bar capacity of 80 mm (3.15 in), while the sub-spindle accepts bar up to 65 mm (2.56 in). Both spindles deliver 26 kW (35 hp) with speeds up to 4,000 RPM through A2-8 spindle noses, providing substantial torque for heavier cuts on larger-diameter stock.

The three-turret layout provides the same productivity advantage as the HQR-200 NEO: two turrets work the main spindle while the third serves the sub-spindle, enabling simultaneous 4-axis cutting that slashes cycle times by 30-50% versus twin-turret machines. Each turret holds 12 tools with BMT live tooling and Y-axis capability for a total of 36 tool stations. The larger spindle bore on the 250 opens up bar feeding of 3-inch stock, a significant capability for shops running medium-diameter production bar work.

MAZATROL SmoothG3 manages the multi-channel control with collision avoidance and full 3-turret simulation. The SmoothG3 variant is purpose-built for machines with three or more turrets, providing intuitive synchronization programming that reduces the learning curve compared to raw multi-channel G-code.

The HQR-250 NEO competes with the Nakamura-Tome NTRX-300, Index G250, DMG Mori NZX 2500, and Okuma MULTUS B250II. It sits at the top of the HQR lineup in terms of chuck size, offering shops with larger-diameter part families the same 3-turret productivity that the HQR-200 NEO provides for 8-inch chuck work.

Strengths & Limitations

Strengths

10-inch chuck with 3.15-inch bar capacity handles larger-diameter parts than the HQR-200 NEO
3-turret, 2-spindle architecture enables 4-axis simultaneous cutting for 30-50% cycle time reductions
36 total tool positions across three turrets virtually eliminate mid-cycle tool changes
26 kW spindles provide more torque than the 200 model for heavier cuts on larger stock
MAZATROL SmoothG3 with collision avoidance and 3D simulation simplifies multi-turret programming
BMT live tooling with Y-axis on all turrets enables complete done-in-one processing

Limitations

Starting at $350K, the premium over 2-turret alternatives requires high-volume production to justify
10,500 kg machine weight demands reinforced foundation and substantial floor space
Multi-channel programming complexity requires experienced operators or significant CAM investment
4,000 RPM spindle speed is lower than the 200 model, limiting surface speed on small-diameter features

Best For

High-volume production of 10-inch chuck parts requiring simultaneous multi-tool operations Automotive manufacturers producing larger drivetrain components like transmission shafts and differential housings Aerospace subcontractors running production campaigns on medium-diameter fittings and structural components Oil and gas manufacturers producing high volumes of valve stems, couplings, and connector bodies Contract manufacturers needing 3-inch bar capacity with 3-turret productivity for larger-diameter production work

Frequently Asked Questions

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

New HQR-250 NEO machines price between $350,000 and $550,000 depending on options. The 10-inch chuck model typically runs $50,000-$75,000 more than the equivalent HQR-200 NEO due to larger spindles and heavier construction.

02 HQR-250 NEO vs HQR-200 NEO: which to choose?

Choose the HQR-250 NEO if your parts require 10-inch chucks or 3-inch bar capacity. The HQR-200 NEO is better for smaller parts where 5,000 RPM spindle speed and 8-inch chucks are sufficient. Both share the same 12.6-inch turning diameter and 33.86-inch turning length.

03 How does the HQR-250 NEO compare to the HQR-250MSY?

The HQR-250MSY has 2 turrets and 2 spindles. The HQR-250 NEO adds a third turret for 4-axis simultaneous cutting, delivering significantly faster cycle times but at $150K-$250K higher cost and greater programming complexity.

04 Can the HQR-250 NEO run 3-inch bar stock?

Yes. The main spindle accepts bar up to 80 mm (3.15 in). With an integrated bar feeder, it can run lights-out production on 3-inch stock, which is a significant capability not available on the smaller HQR-200 NEO.
