Starrag has introduced the larger models of its Heckert X series of five-axis horizontal machining centers (HMCs), with the new X70, X80, and X90 machines tailored for the complete machining of large, heavy-duty components. These models are designed to deliver high precision and efficiency for industries dealing with large workpieces such as gearbox housings, cylinder heads, axles, and other complex components. The machines offer an ideal solution for companies involved in the production of mechanical parts like valve and pump housings, planetary gear carriers, and pallets, headstocks, and spindle frames.
The Heckert X70, X80, and X90 HMCs come with pallet sizes ranging from 24.8″ x 31.5″ for the X70 to 31.5″ x 39.4″ for the X80 and X90 models. These machines are designed to handle heavy parts, with weight capacities ranging from 2,204.6 lb. (1,000 kg) for the X70 to 4,409.2 lb. (2,000 kg) for the X90, making them well-suited for industries requiring heavy-duty machining. Despite the large workpiece capacity, these machines maintain a compact design, with the X70 requiring 18% less installation space than its predecessor, the Heckert HEC 630 X5, offering excellent space-saving benefits while retaining full workpiece capabilities. The working area and displacement circle, as well as permissible workpiece weight and height, remain unchanged from earlier models, ensuring efficient utilization of available space without compromising performance.
What sets the Heckert X70, X80, and X90 apart is their ability to perform integrated turning operations, which adds another layer of versatility to the machining capabilities. With the use of specially developed assemblies and software modules, these machines can execute both classic and complex turning operations, offering the productivity of a machining center with the flexibility of a lathe. Unlike traditional turning lathes, these five-axis machines allow for diverse setup options. Workpieces can be clamped both vertically and during the machining process using the pallet changer, enhancing the flexibility of operations.
The X90 model can handle turning diameters of up to 55.1″, further expanding the machine’s versatility for large components. Additionally, these machines support the use of large tool magazines, ensuring a wide variety of tools can be utilized in the production process.
Starrag’s Heckert X70, X80, and X90 machines are built on a compact, low-vibration machine bed made of grey cast iron, which ensures excellent mechanical accuracy. The thermo-symmetrically designed columns contribute to high performance by minimizing thermal distortion during operations. The use of trimmed guides also ensures that the machines can maintain consistent precision, with software compensation applied to finalize the finishing touches, optimizing overall accuracy.
The rotary/tilt table of these models is robust and designed with two equally sized bearings and a thermally stable construction. This ensures highly dynamic and efficient five-sided machining, enabling operators to handle complex components with precision, speed, and reliability.
The X series machines are also designed with automation in mind. With extended 13-channel clamping hydraulics and optimized interfaces to pallet storage systems and robot cells, the new models are easier to automate than their predecessors. The machines are also compatible with pallets from the older Heckert HEC 630 / 800 X5 models, enabling smooth transitions and greater flexibility in production.
For control, the Heckert X70, X80, and X90 machines come equipped with the Siemens Sinumerik One control system. This cutting-edge system features new hardware and fast sensor technology, ensuring enhanced control over the machining process and greater precision.
In conclusion, the Heckert X70, X80, and X90 models from Starrag represent a significant step forward in the world of five-axis machining, combining high capacity for large and heavy workpieces with a compact design, integrated turning functionality, and advanced automation capabilities. These machines offer a versatile, efficient, and precise solution for heavy-duty industries, from automotive to aerospace, making them ideal for the most demanding manufacturing applications.
