Overview
The Starrag Heckert X90 is the largest model in Heckert's X-series of 5-axis horizontal machining centers, built around a 1,000 mm pallet for the most demanding large-part 5-axis applications. Designed for aerospace, power generation, and defense manufacturers machining large titanium structures, turbine components, and complex contoured housings, the X90 combines Heckert's production-proven horizontal platform with full 5-axis simultaneous capability.
Axis travels of 1,300 x 1,100 x 1,300 mm (51.2 x 43.3 x 51.2 in) provide a massive work envelope for large contoured components requiring multi-angle access. The spindle delivers 10,000 RPM with 55 kW (74 hp) continuous power and 700 Nm of torque through an HSK-A100 taper, with high-torque options exceeding 900 Nm for aggressive roughing in titanium forgings and large steel components. The integrated A/B-axis trunnion provides +/-110 degrees of swivel with continuous C-axis rotation.
Two 1,000 x 1,000 mm pallets come standard, each supporting workpieces up to 2,200 kg (4,850 lb). Tool magazine capacity starts at 80 tools, expandable to 360. Rapid traverse reaches 45 m/min on all linear axes. Roller guideways on all axes provide the rigidity essential for accurate 5-axis contouring of large parts under heavy cutting loads.
The X90 runs on Siemens SINUMERIK 840D sl with advanced 5-axis kinematic transformation and volumetric compensation across the full work envelope. Positioning accuracy of +/-0.007 mm and repeatability of +/-0.004 mm are exceptional for a 5-axis machine at this scale. Built in Chemnitz, Germany, the X90 competes with the largest 5-axis HMCs from Grob, Makino, and SNK. New machines typically price between $1,000,000 and $1,600,000.

Strengths & Limitations
Strengths
- 1,000 mm pallets with 2,200 kg load capacity provide the largest 5-axis horizontal machining platform in the Heckert X-series for oversized aerospace and energy components
- 1,300 x 1,100 x 1,300 mm travel enables 5-axis machining of large structural titanium parts, turbine casings, and complex contoured housings in a single setup
- 55 kW HSK-A100 spindle with 700 Nm torque and high-torque options over 900 Nm handle aggressive roughing in titanium forgings and large steel components
- Roller guideways deliver superior rigidity for accurate 5-axis contouring under the heavy cutting loads typical of large titanium and Inconel parts
- Horizontal orientation provides gravity-assisted chip evacuation critical for large-part titanium and hard-metal machining
- IPS pallet pool integration enables production-scale 5-axis manufacturing of large components with automated part exchange
Limitations
- At $1M-$1.6M, the X90 is a significant capital investment requiring high-value aerospace or energy applications to justify
- 28,000 kg machine weight requires substantial foundation engineering and overhead crane capacity for installation
- Siemens-only control platform limits flexibility for shops running Heidenhain or Fanuc on existing 5-axis equipment
- Limited global dealer network compared to Grob or Makino makes service access challenging outside key European aerospace markets

Frequently Asked Questions
01
The X90 and H100 share similar pallet sizes (1,000 mm) but serve fundamentally different applications. The H100 is a pure 4-axis production machine with 3,000 kg pallet capacity optimized for maximum rigidity in prismatic part machining. The X90 adds a 5th axis for complex contouring but has lower pallet capacity (2,200 kg) due to the trunnion mechanism. Choose the H100 for heavy prismatic production, the X90 for complex contoured parts requiring multi-angle access.
02
The X90 accommodates workpieces up to approximately 1,200 mm in diameter on its 1,000 x 1,000 mm pallets, with a maximum weight of 2,200 kg including fixture. The 1,300 mm X-travel and 1,300 mm Z-travel provide clearance for large parts plus tooling. Actual maximum part size depends on the A-axis swivel clearance required for specific 5-axis operations.
03
Yes, the X90 is well-suited for blisk and impeller machining. The 5-axis simultaneous capability with +/-110 degrees of swivel provides the multi-angle access needed for blade profiles. The HSK-A100 spindle delivers the rigidity needed for accurate blade finishing in titanium and Inconel. Siemens 840D sl with advanced 5-axis kinematics supports the complex toolpath strategies required for turbine component machining.
04
The X90 features comprehensive thermal management including temperature sensors throughout the machine structure, active thermal compensation in the CNC control, thermally symmetric column and bed design, and coolant temperature control. These systems maintain positioning accuracy during extended production runs where thermal drift could compromise part quality, particularly critical for aerospace tolerance requirements.
