HIRUNG · CNC Gantry Machining Center
HPG Series: High-Precision CNC Gantry Machining Centers
The HPG Series is a range of high-precision CNC gantry machining centers built for heavy-duty, large-workpiece cutting. Each machine uses a moving-beam (moving gantry) architecture with a fixed table, giving it the rigidity, thermal stability, and repeatable accuracy that mold, aerospace, and medical manufacturers demand. Whether you machine a single large casting or run mixed-batch production, the HPG Series delivers consistent speed and precision regardless of workpiece weight.
What Is a Moving-Beam CNC Gantry Machining Center?
A moving-beam gantry machining center keeps the worktable stationary while the gantry (crossbeam and spindle carrier) travels over the part. This is fundamentally different from a moving-table or moving-column design, where the heavy table or column must accelerate the full workpiece mass.
Because the moving mass stays constant, the HPG Series can be calibrated once against real load data and then hold accuracy across light and heavy parts alike. The table-fixed layout also places every axial guideway and protective cover above the workpiece, so chips, dust, and cutting fluid never contaminate the rails. The result is longer guideway life, cleaner lubrication, and a footprint up to 60% smaller than an equivalent moving-table machine.
Key Features of the HPG Series CNC Gantry Machining Centers
Ten engineering decisions separate the HPG Series from conventional gantry mills. Together they target the three things that matter most in heavy cutting: rigidity, accuracy retention, and uptime.
01
Uncompromised Load Capacity
The HPG Series handles workpieces of almost any weight. As long as the part fits within the machine envelope, it can be machined precisely — the workpiece mass does not compromise performance.
02
Consistent High-Speed Performance
Movement speed stays matched to the design specification regardless of workpiece weight, delivering high speed, precision, efficiency, and a longer machine life.
03
Stable and Durable Moving Components
Moving parts are engineered for minimal, uniform wear, sustaining accuracy and lengthening service life under continuous operation.
04
Long-Term Precision Retention
Components are designed to minimize impact variation, so the machine keeps its precision even after extended use.
05
Load-Based Movement Calibration
Setup calibration uses actual load data with compensation adjustments. A constant moving mass lets every operation reach high precision.
06
Fixed Moving Mass with Dual Servo Drive
The X-axis uses a dual servo direct-drive system on a constant moving mass, effectively guaranteeing machining accuracy.
07
Compact Footprint
The HPG Series occupies up to 60% less floor space than a traditional moving-table machine with the same processing capability.
08
Enhanced Guideway Protection
All axial guideways and covers sit above the workpiece, blocking debris, dust, and cutting fluid from the rails and keeping rail oil separate from the coolant.
09
Simultaneous Loading and Machining
With proper safety protocols, a new workpiece can be loaded on one side while machining continues on the other, raising throughput.
10
Non-Standard Customization
Travel can be extended to X up to 60 m, Y up to 8 m, and Z up to 3 m, with bespoke widths and heights on request.

Non-Standard Customization
The HPG Series supports non-standard customization. Maximum configurable travel reaches X up to 60 m, Y up to 8 m, and Z up to 3 m, with tailored table widths, heights, and spindle configurations. Contact our sales team or a local dealer for a purpose-built solution.
Innovative Box-in-Box Crossbeam Design for Z-Axis Rigidity
The HPG Series features HIRUNG’s patented box-in-box crossbeam structure with four Z-axis guide rails. This geometry resists torsion and bending during heavy cuts, so the spindle stays exactly where it is commanded even under aggressive metal removal.
The Y-axis beams are reinforced with internal stiffeners that never deform, and the Y-axis ball screw runs on a linear-guideway support so it cannot deflect and compromise accuracy — a design especially important on large-span machines.
Precision Casting & Rigidity — HIRUNG's Cast Iron Formula
Machine stability begins in the foundry. HIRUNG uses a proprietary cast-iron formula and a strict, multi-stage process to guarantee the rigidity and dimensional stability of every base and column:
After casting, every component goes through a strict annealing procedure to relieve internal stress, preventing warpage over the machine’s service life. The cast iron itself is formulated for high rigidity and stability — the ‘true material counts’ philosophy behind HIRUNG’s secret formula.

Spindle & Drive System
The spindle is the heart of any machining center. The HPG Series pairs a heavy-duty BT50 spindle with Japanese NSK P4-class bearings in a dust-free assembly, holding spindle suspension within 0.003 mm.
Standard & Optional Spindles
Standard: 10000 rpm direct-coupled BT50 spindle.
Optional: 18000 / 24000 rpm built-in electric spindle (ISO#40 — BT40 / BBT40 / HSK A63); also configurable with BT50 / HSK A100. For maximum torque, a Germany ZF gearbox spindle delivers up to 380 Nm for heavy cutting.
The 5-axis series adopts Italian HSD and German TRAMEC high-power spindles (24–93 kW) for large cutting force with high precision. Configuration options vary by model — contact the sales manager for details.
5-Axis Machining Capability
HPG 5-axis configurations use MEPRO rotary tables — the T70 (standard, single-arm support) and T200 / T400 (optional, double-arm support). A/C axes deliver ±110° / ±360° rotation, 8 arc-second positioning accuracy, 4 arc-second repeatability, and rotational torque up to 1600/3000 Nm, enabling complex 5-sided and 5-axis simultaneous machining.
| MEPRO model | T70 (standard) | T200 (optional) | T400 (optional) |
|---|---|---|---|
| A-axis rotation | ±110° | ±110° | ±110° |

5-axis models use SIEMENS 840D control. Full specifications on request.
Core Components & Build Quality
Every HPG machine is built from globally sourced, name-brand components selected for heavy-duty reliability:
- Guideway: Japan THK heavy-load roller guideways; the Z-axis runs on four roller guide rails for heavy and high-speed cutting.
- Ball screw: Japanese P4-class ball screws with 3+2 pre-tensioning for rigidity and long life; all couplings are Germany KTR.
- Electrical: Germany Schneider / OMRON components in a CE-standard control cabinet built for export to Europe.
- Optional FAGOR optical scale for even higher positioning accuracy.
- Tooling: 20-tool magazine (optional) with a 2.2-second tool exchange; up to four 20-tool units for high-mix production.
- Lubrication: volumetric distributor with offline oiling for precise, waste-free guideway lubrication.
- Control: SIEMENS 828D standard; SIEMENS 840D for 5-axis; HEIDENHAIN optional.
Applications of HPG Gantry Machining Centers
The large envelope, high rigidity, and configurable 3- to 5-axis capability make the HPG Series suitable for precision machining of oversized and complex parts across multiple industries.
Mold & Die
Large plastic molds, die-casting dies, and stamping tools are where gantry centers excel. The HPG Series removes massive material volumes in roughing, then holds fine finishing passes for superior surface quality — all on a single setup. Its stable cast base keeps the part accurate through long, demanding cuts.
Aerospace
Aerospace structural parts demand tight tolerances on large aluminum and titanium components. The moving-beam design and box-in-box crossbeam maintain geometric accuracy on long spans, while optional 5-axis tables enable complex contoured surfaces in fewer setups.
Large-Part & Heavy-Industry Machining
Beyond the three core sectors, HPG gantry centers are widely used for energy-equipment components, marine and shipbuilding parts, rail-transit structures, and general large-workpiece machining where a moving-table VMC simply cannot reach. Custom spans up to 60 m make even oversized fabrications achievable.
Medical Instruments
Medical implants and instrument components require flawless surface finish and repeatable precision. HIRUNG’s strict casting, annealing, and inspection discipline — backed by ISO 9001 — supports the quality traceability medical manufacturers expect.
