60,000 professionals from over 50 manufacturing sectors are expected to be attracted to Global Industry Paris by the organizers from March 30 to April 2 in the north of the French capital. The chances are good, as the fair is known for its innovations. Starrag particularly targets demanding users. In Hall 6, Stand 6W151, the Swiss machine manufacturer demonstrates how even small components made from challenging materials with tight tolerances can be efficiently produced in a continuous manufacturing process.
Keeping critical manufacturing steps under control
Efficiency, safety, and sustainability will be the focus across industries according to the organizer GL events Exhibitions Industries in 2026. Implementable manufacturing processes that combine automation, digital process control, and efficient resource use are in demand. Global Industry Paris thus highlights applications that can measure how stable and reproducible processes run even in very critical manufacturing steps.
How this is achieved in practice is demonstrated by Starrag on a Bumotec 191neo, a highly flexible turning-milling center for the complete machining of precise small parts with high value creation. The system is designed for continuous processes and combines several machining steps on one platform – a prerequisite for applications where tight tolerances, surface quality, and process stability are essential.
Leading effect: Fuel injectors for engines
This particularly concerns fuel injectors for engines, which, despite their small size, are among the function-critical components of an aircraft. They have a direct impact on combustion, emissions, and operational safety.
How these injectors can be produced quickly, highly precisely, and reliably on the Bumotec 191neo is demonstrated by Starrag's specialists in just about nine minutes. The raw material is bars with a diameter of 9.5 mm, which are completely machined in a single setup with 15 tools. The process is demonstrated with a component made of stainless steel, which represents the later production from Inconel. The integrated deburring ensures consistently high surface quality and a constant fuel flow.
Complete machining in a single setup
The complete manufacturing process is represented by the Bumotec 191neo in a single setup. Turning, drilling, milling, machining of the internal fuel channels, and deburring seamlessly interlock. In this way, even with complex geometries, tight dimensional and positional tolerances in the range of a few micrometers can be reliably maintained. At the same time, continuous machining improves roundness, surface quality, and reproducibility.
Benchmark for vertical turning: Berthiez VT
The French product line Berthiez from Saint-Étienne presents its new vertical lathes VT 14 and VT 20. These complete the VT series along with the larger VT 28. Characteristic of the VT series are a particularly rigid, vibration-damping cast construction, powerful main and feed drives, and a consistent design for precise complete machining.
The common denominator with the Bumotec 191neo is the principle of continuous machining in a single setup: Depending on the configuration, the VT machines allow for turning, milling, drilling, and grinding on one platform. The VT 14 is designed for the highly precise machining of rotationally symmetrical components with diameters up to about 1.4 m. The VT 20 expands this spectrum to component diameters of up to about 2 m and workpiece weights of up to 8 t. Both machines are designed for tight dimensional and positional tolerances and are suitable for demanding applications in the aerospace industry or the wind power sector, such as in structural components.
