Overview

The Starrag Heckert H90 is a 900 mm pallet 4-axis horizontal machining center engineered for heavy-duty production of large prismatic parts in power generation, heavy equipment, oil and gas, and large-scale automotive applications. Sitting near the top of Heckert's compact H-series range, the H90 delivers a massive work envelope with the precision and thermal stability that define the Heckert brand.

Axis travels of 1,200 x 1,100 x 1,200 mm (47.2 x 43.3 x 47.2 in) accommodate very large castings, structural weldments, and complex multi-face components in a single setup. The spindle delivers 10,000 RPM with 55 kW (74 hp) continuous power and 700 Nm of torque through an HSK-A100 taper, with a high-torque option reaching 900 Nm for sustained heavy roughing in cast iron, structural steel, and demanding alloys.

Two 900 x 900 mm pallets come standard, each supporting workpieces up to 2,500 kg (5,512 lb). The B-axis rotary table provides 0.001-degree indexing resolution. Tool magazine capacity starts at 80 tools with expansion options to 300 for complex production cells. Rapid traverse reaches 45 m/min across all linear axes. Roller guideways ensure the rigidity demanded by heavy interrupted cuts at this scale.

The H90 runs on Siemens SINUMERIK 840D sl with full IPS pallet pool integration capability. Positioning accuracy of +/-0.007 mm and repeatability of +/-0.004 mm are outstanding for this work-envelope class. Built in Chemnitz, Germany, the H90 bridges the gap between Heckert's compact H-series and the large-format HEC range. New machines typically price between $750,000 and $1,100,000.

Strengths & Limitations

Strengths

900 mm pallets with 2,500 kg load capacity handle very large castings, weldments, and tombstone fixtures that exceed the capability of standard 800 mm pallet HMCs
1,200 x 1,100 x 1,200 mm travel provides an enormous work envelope for single-setup machining of complex multi-face components
55 kW continuous spindle with HSK-A100 taper and 700 Nm torque delivers sustained cutting authority in cast iron, steel, and demanding alloys
Roller guideways on all axes ensure the rigidity required for heavy interrupted cuts at this work-envelope scale
Thermally symmetric Heckert design maintains dimensional stability across multi-shift production despite the large machine structure
Full IPS pallet pool compatibility enables integration into large-scale flexible manufacturing systems

Limitations

Starting at $750K, the H90 requires significant capital investment with a more limited dealer network compared to Japanese and Korean competitors
26,000 kg machine weight demands substantial foundation engineering, pit work, and heavy rigging for installation
Siemens-only control platform may not align with shops standardized on Fanuc, adding programming workflow and training costs
Large footprint and installation requirements make this unsuitable for shops without adequate floor space and overhead crane capacity

Best For

Power generation manufacturers machining turbine housings, generator frames, and large structural castings requiring 900 mm pallet capacity Heavy equipment OEMs producing large cast iron and steel components for mining, construction, and industrial machinery Oil and gas equipment manufacturers cutting valve bodies, pump housings, and blowout preventer components in demanding materials Large-scale automotive powertrain facilities machining oversized engine blocks, transfer case housings, and structural castings Production facilities building multi-machine FMS cells for lights-out manufacturing of large prismatic parts

Frequently Asked Questions

01 How does the Heckert H90 compare to the HEC 1250?

The H90 uses a 900 mm pallet with 2,500 kg capacity and travels of 1,200 x 1,100 x 1,200 mm. The HEC 1250 steps up to a 1,250 mm pallet with significantly higher load capacity and larger travels, targeting truly large workpieces in power generation and heavy industry. The H90 is the right choice when 800 mm pallets are too small but the HEC 1250's cost and footprint exceed requirements.

02 What is the maximum workpiece size the H90 can handle?

The H90 accommodates workpieces up to approximately 1,200 mm in diameter and 1,400 mm tall on its 900 x 900 mm pallets, with a maximum weight of 2,500 kg. The 1,200 mm X-travel and 1,200 mm Z-travel provide clearance for large parts plus fixture tooling. For workpieces exceeding these dimensions, consider the HEC 1250 or HEC 1600.

03 What coolant and chip management does the H90 include?

The H90 features a high-volume coolant system with through-spindle coolant delivery standard, supporting both flood and high-pressure options up to 70 bar. A hinged belt chip conveyor handles the heavy chip loads generated by large-format machining. An optional high-pressure coolant system at 80 bar or higher is available for deep-hole drilling and demanding material applications.

04 Can the H90 be used for 5-axis machining?

The H90 is a 4-axis machine with B-axis indexing at 0.001-degree resolution. For 5-axis capability in this size class, Starrag offers the Heckert X-series which adds a fifth axis integrated into the table. The H90 focuses on maximum rigidity and load capacity for 4-axis production work, where simplicity and stability trump 5-axis flexibility.
