The 5-axis Heckert X compact series is now complete, Starrag reported. To complement the Heckert X50 that has been available since April 2022, Starrag launched the larger Heckert X70, X80 and X90 versions in April 2025. These supersede the HEC 630 X5 and HEC 800 X5 models, adding to their already familiar range of applications. For instance, the Heckert X90 can be used to machine larger workpieces.

With pallet sizes of 24.8" x 31.5" (Heckert X70) and 31.5" x 39.4" (Heckert X80 and X90), the new 5-axis horizontal machining centers are suitable for the complete machining of large components, including those that may be quite heavy. This is because the loading weight of the new additions range from 2,204.6 lbs. (Heckert X70) to 4,409.2 lbs. (Heckert X90). As such, these models are focused on the 5-axis heavy-duty machining of gearbox housings and cylinder heads, axles, valve and pump housings, planetary gear carriers and machine components, including pallets, headstocks and spindle frames.

"What sets the new machining centers apart is their compact design and, with it, a smaller footprint," said a company spokesperson. "The Heckert X70 requires 18% less installation space than its predecessor, the Heckert HEC 630 X5. The other models of the X series also offer similar space savings. However, the machine's compact proportions do not mean the user has to compromise in terms of their workpieces. The working area and displacement circle remain unchanged, as do the permissible workpiece weight and workpiece height."

Furthermore, turning as a technology is an integral part of the machine concept and can be configured as an option. Using specially developed assemblies and software modules, classic and complex turning operations can be performed with the productivity of a machining center.

Unlike a turning lathe, the machine benefits from a variety of set-up options. Not only can the workpieces be clamped vertically for added convenience, but they can also be clamped during the machining operation due to the pallet changer. In terms of tools, all versions of the large tool magazines can be used, and turning diameters in the working area can measure up to 55.1" (Heckert X90).

Like all the new compact machining centers from Starrag, the new Heckert X70, X80 and X90 are based on a compact, low-vibration machine bed made of grey cast iron. This basis, combined with the thermo-symmetrically designed columns, provides high basic mechanical accuracy, due in part to trimmed guides. This means that the software compensation process need only add the finishing touches.

The new Heckert X70, X80 and X90 are based on the comparable machine sizes of the 4-axle Heckert H-series. Instead of the NC rotary table installed in the earlier models, the X-series models feature a rotary/tilt table-an in-house development. Not only does the tilting unit have two equally sized bearings, but also a thermally stable design. This means that the machines are capable of complete 5-sided, highly dynamic machining of complex components.

Of particular importance to the developers was ensuring the compatibility of the pallets on the new Heckert X70, X80 and X90 models. The pallets are interchangeable with those of the H series. What is more, the pallets from the older Heckert HEC 630/800 X5 machines can still be used on the new X models.

All machines in the 5-axis compact series are fitted with the latest SINUMERIK ONE control system, with new hardware and fast sensor technology. They are also easier to automate than their predecessors. This is due in part to the extended 13-channel clamping hydraulics and optimized standard interfaces to pallet storage systems and robot cells.
