Starrag, which unveiled its new large-machine series in November 2024, says the four planned Heckert models will be launched and presented to the market in stages throughout 2025.
The company’s HPMS (High Performance Machining Systems) business unit, which includes the Chemnitz and Rorschacherberg sites, has developed a new large-machine construction kit from which new machining centres can be derived.
Development engineers considered the latest technical aspects when redesigning the large Heckert machines. For example, the frame components, such as the beds and columns, were optimised for thermal symmetry. If the ambient temperature changes, the core components expand or contract evenly in all directions. This behaviour is predictable and correctable. The chip fall in the area between the work spindle and the workpiece has also been improved so that hot chips have minimal opportunity to transfer heat to the workpiece or the machine.
An important advantage of the new machines is the improved productivity. The decisive factor here is an increase in the diameter of the ball screws from 63 to 80 mm. A further stiffening of the structural components complements this improvement. As a result, users can achieve even higher cutting values, increase chip volumes and ultimately reduce machining times. The machine has also become faster. Instead of a 40 m/min rapid traverse rate, it now enables 50 m/min, reducing non-productive times.
The approximately 20% smaller footprint is another benefit in light of high floor space costs. This reduction is primarily due to the repositioning of an energy chain, which enables further integration of the chip conveyor into the machine.
