Starrag Five-Axis Enables Complete Machining of Large Parts in Compact Footprint

Source: Starrag

Starrag’s five-axis Heckert X compact series now features the larger Heckert X70, X80 and X90 versions.

With pallet sizes of 24.8" × 31.5" (Heckert X70) and 31.5" × 39.4" (Heckert X80 and X90), the new five-axis HMCs are suitable for the complete machining of large components, including those that may be quite heavy. This is because the loading weight ranges from 2,204.6 lb. (1,000 kg) for the Heckert X70 to 4,409.2 lb. (2,000 kg) for the Heckert X90. As such, 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 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 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 productivity of a machining center.

Unlike a turning lathe, the machine benefits from a variety of setup options. The workpieces can not only be clamped vertically but also 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).

The 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 very high basic mechanical accuracy, due in part to trimmed guides. This means that the software compensation process need only add the finishing touches.

The Heckert X70, X80 and X90 feature a robust rotary/tilt table with 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.

The Heckert X70, X80 and X90 models are compatible with pallets and can be interchanged with those of the H series. The pallets from the older Heckert HEC 630 / 800 X5 machines can still be used on the X models.

Additionally, all machines in the five-axis compact series are fitted with Siemens’ latest Sinumerik One control system, with new hardware and fast sensor technology. They are also said to be easier to automate than their predecessors due to the extended 13-channel clamping hydraulics and optimized standard interfaces to pallet storage systems and robot cells.
