Overview
The Starrag Heckert X80 is a 5-axis horizontal machining center built around an 800 mm pallet, offering full simultaneous 5-axis capability for large aerospace, energy, and heavy industrial components. The X80 represents the heavy-duty end of the Heckert X-series, integrating the fifth axis directly into the table while providing the pallet load capacity and spindle authority needed for demanding titanium and Inconel applications.
Axis travels of 1,100 x 1,000 x 1,100 mm (43.3 x 39.4 x 43.3 in) provide a substantial work envelope for large contoured components. The spindle delivers 10,000 RPM with 50 kW (67 hp) continuous power and 600 Nm of torque through an HSK-A100 taper, with optional high-torque configurations reaching 800 Nm for aggressive roughing in titanium and steel. The integrated A/B-axis trunnion provides +/-110 degrees of swivel with continuous C-axis rotation.
Two 800 x 800 mm pallets come standard, each supporting workpieces up to 1,800 kg (3,968 lb). Tool magazine capacity starts at 80 tools, expandable to 300. Rapid traverse reaches 50 m/min on all linear axes. Roller guideways on all axes ensure the rigidity needed for accurate 5-axis contouring under heavy cutting loads.
The X80 runs on Siemens SINUMERIK 840D sl with advanced 5-axis kinematic transformation and volumetric compensation. Positioning accuracy of +/-0.006 mm and repeatability of +/-0.003 mm meet aerospace structural requirements. Built in Chemnitz, Germany, the X80 competes with large-format 5-axis HMCs from Grob, Makino, and Mitsui Seiki. New machines typically price between $800,000 and $1,200,000.

Strengths & Limitations
Strengths
- Full 5-axis simultaneous capability on an 800 mm pallet platform handles large aerospace structural components that smaller 5-axis machines cannot accommodate
- 50 kW HSK-A100 spindle with 600 Nm torque provides the cutting authority needed for titanium and Inconel 5-axis machining
- 1,100 x 1,000 x 1,100 mm travel offers a large work envelope for 5-axis parts requiring extensive tool access from multiple angles
- 1,800 kg pallet load capacity handles heavy fixtures and large titanium forgings common in aerospace structural applications
- Roller guideways deliver the rigidity needed for accurate 5-axis contouring under the heavy cutting loads typical of hard metal machining
- IPS pallet pool integration enables production-scale 5-axis manufacturing with automated part exchange
Limitations
- At $800K-$1.2M, the X80 requires substantial capital investment with a narrower dealer network than mainstream 5-axis brands
- 24,000 kg machine weight requires significant foundation preparation and rigging capability
- Siemens-only control platform limits appeal for shops running Heidenhain or Fanuc on existing 5-axis equipment
- +/-110 degree swivel range is slightly less than the X50 and X70, though still sufficient for most aerospace geometries

Frequently Asked Questions
01
Both are large-format 5-axis HMCs targeting aerospace production. The X80 uses roller guideways and Siemens 840D sl, emphasizing rigidity and European build quality. The Makino uses its proprietary Professional 6 control, box guideways, and offers exceptional spindle technology. Makino has a stronger presence in North American aerospace, while the X80 excels in European facilities and IPS pallet pool integration. Both deliver aerospace-grade accuracy.
02
The standard spindle delivers 10,000 RPM with 600 Nm torque through HSK-A100. A high-torque option increases to approximately 800 Nm for aggressive roughing in titanium forgings. A high-speed option at 14,000 RPM trades torque for speed in aluminum-intensive applications. All variants include thermal compensation for dimensional stability during long 5-axis production runs.
03
Yes, the X80 is well-suited for titanium machining. The 50 kW HSK-A100 spindle provides the torque and rigidity needed for titanium roughing, while roller guideways maintain accuracy under heavy cutting loads. The horizontal orientation provides superior chip evacuation critical for titanium machining. Through-spindle coolant up to 70 bar further supports titanium cutting performance.
04
Integrating the 5th axis into the table rather than the spindle head maximizes spindle rigidity and eliminates the compliance issues associated with head-swivel architectures. The table-table kinematics provide a more rigid cutting platform, particularly important when machining titanium and Inconel where cutting forces are high. The trade-off is a reduced swivel range compared to some head-swivel designs.
