Overview

The Heckert HEC800 is the large-pallet flagship of the Heckert horizontal machining center range, built around an 800 mm pallet with 2,000 kg load capacity for machining large automotive structural components, aerospace frame sections, large hydraulic manifolds, and heavy industrial machinery components. At this scale, the HEC800 competes with machines like the Okuma MA-800H, Mazak HCN-8800, and DMG Mori NHX 8000 in a segment defined by the intersection of part weight, machining precision, and automated pallet handling.

The HEC800 moving-column design maintains the structural rigidity needed for heavy-cut interrupted machining on large cast iron structures while enabling the traverse distances required to cover an 800 mm pallet surface completely. The rotary pallet table provides four-sided access for complete prismatic machining in a single setup, and at 2,000 kg pallet capacity, the machine handles some of the largest workpieces in the HMC class without requiring a dedicated floor-type machine.

Spindle power at up to 65 kW with over 400 Nm of torque makes the HEC800 capable of aggressive face milling and deep boring on large cast iron and fabricated steel structures. The 800 mm pallet size with 1,000 x 1,000 mm travel on the table enables large gearbox housings, aerospace wing-rib machining fixtures, and large pump and compressor casings to be machined completely in one clamping.

Like the smaller HEC machines, the HEC800 benefits from Starrag Group engineering resources and manufacturing standards. The machine is used in European heavy-industry and automotive Tier-1 supplier plants where machine reliability over 20-year production lifecycles is as important as initial specifications.

Strengths & Limitations

Strengths

800 mm pallet with 2,000 kg load capacity covers the largest HMC-class workpieces, including large gearbox housings and aerospace structural frames
65 kW / 420 Nm spindle provides aggressive material removal capability on large cast iron and fabricated steel structures in production volumes
HSK-A100 taper provides maximum rigidity for large-diameter face mills and heavy boring operations on large workpieces
Starrag Group engineering standards validated by European heavy-industry customers who rely on 20-year machine lifecycle accuracy retention

Limitations

At $750K-$1.2M, the HEC800 is a major capital investment with long payback periods unless spindle utilization is consistently high
At 40,000 kg, the HEC800 requires a reinforced foundation, overhead crane for workpiece loading, and a dedicated high-ceiling shop bay
North American service coverage is limited; shops outside Europe should thoroughly evaluate Heckert dealer support before committing to this machine class

Best For

Automotive structural and powertrain manufacturers machining large engine blocks, gearbox cases, and axle housings in high-volume production Aerospace manufacturers machining large structural frames, wing ribs, and bulk-head fixtures in aluminum and titanium alloys Energy sector manufacturers machining large compressor and pump housings, gearbox cases, and turbine structural components Heavy industrial machinery manufacturers machining large press frames, hydraulic manifolds, and large mechanical sub-assemblies

Frequently Asked Questions

01 What pallet size does the HEC800 use and what can fit on it?

The HEC800 uses an 800 x 800 mm pallet with 2,000 kg load capacity. Typical workpieces include large automotive engine blocks and transmission cases (100-600 kg), aerospace structural panels and wing rib fixtures (200-800 kg), large hydraulic manifolds (50-400 kg), and gearbox housings for industrial equipment (200-1,500 kg). The 1,250 x 1,100 x 1,100 mm travel covers the full 800 mm pallet surface.

02 How does the HEC800 compare to the Okuma MA-800H?

Both are 800 mm pallet horizontal machining centers for large-part production. Okuma has a significantly stronger service and parts network in North America and the Okuma OSP control has a large operator base. Heckert runs Siemens Sinumerik 840D sl preferred in European environments. Accuracy and spindle specifications are comparable. North American shops should carefully evaluate service response time before selecting Heckert over Okuma at this investment level.

03 What spindle taper does the HEC800 use and why?

The HEC800 uses HSK-A100, which provides higher clamping force and rigidity than HSK-A63 at the large tooling diameters typical for 800 mm pallet machining. HSK-A100 is standard for HMCs in this size class where face milling cutters 200-400 mm in diameter and large boring heads require maximum spindle interface rigidity to prevent chatter.

04 What foundation requirements does the HEC800 have?

At 40,000 kg, the HEC800 requires a heavy reinforced concrete foundation, typically 1,200-1,800 mm deep depending on local soil conditions. An overhead crane of at least 5 tons is required for workpiece loading at this pallet size and weight capacity. Heckert provides detailed foundation and utility drawings during the order engineering process.

05 Can the HEC800 operate in lights-out automated production?

Yes. The HEC800 supports multi-pallet automation systems for lights-out operation. Because workpieces in this size class typically run 2-8 hours per pallet, automated pallet systems with 4-20 pallets provide multiple shifts of unattended production. Robotic or gantry workpiece loading is also available for raw casting-to-finished-part automation.
