HORIZONTAL BORING & MILLING CENTER
Heavy-duty capability,
intelligently engineered.
The AXERA HBM Series is engineered to maximise productivity in the machining of large and demanding workpieces. A rigid machine structure, high-torque spindle technology and optimised thermal stability deliver exceptional cutting performance, long-term accuracy and reliable operation under continuous heavy-duty machining.
Multiple spindle configurations and an optional CNC precision facing head enable complex processes in a single setup, helping manufacturers improve throughput while reducing overall manufacturing costs.
ENGINEERING DEEP DIVE
Built for the
heaviest work.
Rigid Machine Foundation
Meehanite-licensed, stress-relieved cast structures and roller-type linear guideways create a stable, high-load platform for large-part horizontal boring and milling.
KEY BENEFITS
- High rigidity and vibration damping for continuous heavy-duty machining.
- Roller-type guideways designed for high load capacity.
- C3-class preloaded double-nut ball screws for stable axis motion.
Long-Travel Support
Ball-screw support is provided for travels of 3 metres and above to preserve process stability.
Hardened Spindle & Quill
The spindle and quill sleeve are hardened to a reference HRC 52–55 for long-term durability.
Spindle, Quill & Rotary Table
The T-Type platform offers 110 mm, 130 mm and 150 mm spindle-quill diameters, ISO 50 tooling, two-speed gearbox strategies and high-load rotary tables.
KEY BENEFITS
- Two-speed gearbox combines low-speed torque with versatile general machining.
- CNC rotary table with 0.001° indexing reference and encoder feedback.
- Extended 150 mm quill available for larger-process requirements.
High-Torque ISO 50 Spindle
The ISO 50 spindle interface and two-speed gearbox support powerful cutting and reliable general machining.
Extended Quill Platform
HBM-5TU and HBM-5TLU incorporate the extended 150 mm quill concept with 900 mm W-axis travel.
Rotary Accuracy Reference
Positioning accuracy: 15 arcsec; repeatability: 4 arcsec; encoder accuracy: ±5 arcsec.
Single-Setup Process Capability
Arm-type automatic tool changers, optional accessory heads and servo facing-head configurations expand the process range while minimising workpiece transfers and re-clamping.
Tool Management
ATC capacity ranges from 40 / 60 tools on HBM-3T to 60 / 120 tools across larger configurations.
Precision Facing Head
The optional CNC precision facing head provides 200 mm radial traverse, a 1,250 mm maximum working diameter and Ra 1.6 μm surface-roughness reference.
UT5 Servo Facing Head
The HBM-5T platform supports UT5-500 / UT5-630 servo facing heads for one-clamping milling, tapping, drilling and facing operations. Its U-axis radial slide enables outer and inner facing, cylindrical and conical boring, threading and radius machining.
KEY BENEFITS
- Completes multiple facing and boring operations in a single clamping.
- U-axis radial slide expands machining capability for complex large parts.
- Designed to support accurate finishing and productive heavy-duty processing.
Working Range
- Radial traverse: 200 mm
- Maximum working diameter: 1,250 mm
- Feed rate: 1–400 mm/min
Accuracy Reference
- Repeatability: 0.005 mm
- Boring accuracy: H7
- Facing accuracy: 0.02 mm
- Surface roughness: Ra 1.6 μm
