Germany-based machine tool manufacturer Starrag has introduced a new generation of large-scale machining centres, with four models slated for market rollout throughout 2025. The innovation stems from the company’s High Performance Machining Systems (HPMS) division, encompassing its Chemnitz and Rorschacherberg facilities.
This latest development features a completely redesigned modular construction kit, allowing customers to configure machining centres tailored to their specific requirements. The modular system draws from the trusted Heckert principles of rigidity and precision—hallmarks that have long defined Starrag’s machining technology.
One of the new models, showcased at an Open House event in Chemnitz, is set to succeed the widely used Heckert HEC Large Athletic series. Importantly, Starrag has maintained key motion sequences, ensuring that transitioning from older systems to the new line remains smooth. Existing customers will benefit from easy integration of previous devices and NC programs, limiting disruption and reducing adaptation time.
Enhanced Design for Precision and Stability
Incorporating cutting-edge design updates, the revamped large machines emphasize thermal symmetry. Optimized frame components—including machine beds and columns—now expand or contract uniformly in response to ambient temperature changes. This symmetry ensures predictable behavior and facilitates straightforward correction during operation.
Starrag also refined chip evacuation between the spindle and the workpiece to minimize heat transfer, improving machining stability and protecting sensitive components from thermal stress.
Performance Boost and Footprint Reduction
Productivity gains are another standout feature. A significant increase in the ball screw diameter—from 63mm to 80mm—boosts structural stiffness and cutting performance. Users can expect faster cutting speeds, higher chip volumes, and reduced machining times.
The new machines also improve rapid traverse speeds, now reaching 50 metres per minute compared to the previous 40 m/min. This advancement helps reduce non-productive time and streamlines operational efficiency.
Additionally, the redesign has led to a 20% reduction in the machine’s overall footprint. By repositioning the energy chain, the chip conveyor is now more compactly integrated, saving valuable floor space—a critical advantage amid rising facility costs.
Heavy Payload and User-Friendly Maintenance
Structural upgrades now support payloads of up to 20 tonnes, enabling the machines to accommodate larger, heavier components and attract new customer segments. Maintenance access has also been enhanced, with a redesigned energy console at the machine’s rear consolidating all service-relevant elements into one location for easier management.
Customisable Modular Architecture
A key innovation lies in the system’s flexible modular design. With four predefined sizes and fully interchangeable structural components, users can create tailored machining solutions. A wide variety of spindles and machining heads are available, with future upgrades set to include interchangeable attachment heads on both the quill and fork head for additional geometric flexibility and speed options.
Expanded Tool Management Capabilities
The new machine series features expanded tool magazine options. In addition to the chain and tower magazines, engineers at Starrag’s Chemnitz facility developed a new modular rack magazine with a capacity of up to 828 tools. These tools can be up to 380mm in diameter, 1,500mm long, weigh 100kg, and feature a tilting moment of 150Nm.
A newly developed tool management software maximizes packing density and operational efficiency. It designates a quick-change area near the tool changer, automatically ejects tools upon reaching their lifespan, and logs usage data for all tools.
A Leap Forward in Large-Scale Machining
With the upcoming launch of this high-performance modular machine series, Starrag aims to meet the evolving demands of global manufacturing industries. By combining proven mechanical principles with cutting-edge enhancements in productivity, thermal stability, and tool management, Starrag is positioning itself as a leader in next-generation large-scale machining solutions.
The 2025 rollout marks a pivotal step for Starrag in aligning traditional industrial engineering with modern efficiency and flexibility—setting new standards in machine tool innovation.
