With pallet sizes of 25 × 31 in. (630 × 800 mm) (Heckert X70) and 31× 39 in. (800 × 1,000 mm) (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. The loading weight of the “newbies” ranges from 2,205 lb. (1,000 kg) (Heckert X70) to 4,409 lb. (2,000 kg) for the 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 high precision machine components, including pallets, headstocks, and spindle frames.

The new machining centers offer a smaller footprint due to their compact design. 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, 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 setup options. Not only can the workpieces be clamped vertically for added convenience, but 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 in. (1,400 mm) (Heckert X90). Starrag has upheld the typical characteristics for which the Heckert models are known. These are robust, powerful, and fast machines that offer exceptional accuracy and reliability for years. Like all the new compact machining centers from the Chemnitz-based company, the new Heckert X70, X80 and X90 are built on a compact, low-vibration machine bed made of grey cast iron. This base, combined with the thermo-symmetrically designed columns, ensures very high mechanical accuracy, thanks to trimmed guides. This means that the software compensation process only needs to add the finishing touches.
