STARRAG is introducing three new models to complete its Heckert X compact five-axis. Complementing the Heckert X50 unveiled three years ago, the larger Heckert X70, X80 and X90 versions are now available, superseding the HEC 630 X5 and HEC 800 X5 models, adding to their range of applications.
The new Heckert X70 will be exhibited at EMO 2025 in Hanover, Germany, in September.
With pallet sizes of 24.8x31.5 in. (630x800 mm) for the Heckert X70; and 31.5x39.4 in. (800x1,000 mm) for the 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 weights for the new models range from 2,204.6 lb. (1,000 kg) for the Heckert X70; to 4,409.2 lb. (2,000 kg) for the Heckert X90. These models are focused on the five-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.
The new machining centers are distinguished by a compact design and a smaller footprint. The Heckert X70 requires 18 percent less installation space than its predecessor, the Heckert HEC 630 X5. The other models of the X series 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 height.
Turning technology is integral to the machine design, and can be configured as an option. Using specially developed assemblies and software modules, both classic and complex turning operations can be performed with the unrivalled productivity of a machining center.
Unlike a turning lathe, the machine benefits from a variety of set-up options. The workpieces be clamped vertically for added convenience, or they can in fact be clamped during the machining operation thanks 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 in. (1,400 mm) (Heckert X90).
Starrag explains that the typical Heckert design characteristics are included, namely that they are robust, powerful and fast machines that provide high accuracy and long-term reliability.
The new Heckert X70, X80, and X90 are built on a compact, low-vibration cast gray iron machine bed, and include thermo-symmetrically designed columns, ensures very high basic mechanical accuracy, thanks 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 four-axle Heckert H-series. Instead of the NC rotary table installed in those models, the X-series machines feature a robust rotary/tilt table that has two equally sized bearings, and a thermally stable design. This means that the machines are capable of complete five-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 the H series pallets, and pallets from the older Heckert HEC 630 / 800 X5 machines can be used on the new X models.
All machines in the five-axis compact series are fitted with Siemens latest SINUMERIK ONE control system, with new hardware and fast sensor technology, and they are easy to automate thanks in part to the extended 13-channel clamping hydraulics and optimized standard interfaces to pallet storage systems and robot cells.
