Akris Group > Our expertise > High-precision machining technologies
At AKRIS Group, high-precision machining is much more than just a manufacturing process; it’s the foundation of our industrial identity. In an ecosystem where errors are measured in microns, we have combined the strengths of pioneering brands like Sumca and S3M to offer a comprehensive solution to the most complex technological challenges. This consolidation of sites under akris-group.com now allows us to present a unified technological showcase, capable of meeting the needs of the most demanding sectors, such as aerospace, advanced medical, and nuclear.
Le cœur de notre dispositif industriel repose sur l’Usinage Grande Vitesse (UGV) et nos centres d’usinage 5 axes de dernière génération. This technology allows complex geometries to be worked on in a reduced number of setups, thus guaranteeing impeccable dimensional and geometric accuracy.
• Performance and responsiveness : Thanks to high rotational speeds and rapid feed rates, we reduce cycle times while improving the surface finish of critical parts.
• Limitless complexity : 5-axis machining eliminates design constraints. Whether for turbine blades, medical implants, or defense components, our CNC machines handle the most challenging angles with perfect fluidity.
• Combined machining : We also integrate CNC milling and turning capabilities to deliver finished parts ready for assembly, minimizing the risks associated with multiple rework.
Where conventional machining stops, Sumca’s expertise takes over. We have mastered micromachining for the production of miniature components for advanced electronics and connectors.
Our workshops are equipped to handle extremely tight tolerances on small-scale complex parts. This ability to push the boundaries of the possible relies on high-level craftsmanship, supported by cutting-edge technologies. Each micro-part is the result of a prior analysis of mechanical constraints, ensuring total reliability once integrated into your systems.
The AKRIS Group distinguishes itself by its ability to machine materials known for their difficulty in implementation. Under the aegis of our expert brands like Usicarb, we work with tungsten carbide, ceramics and other high-hardness alloy steels.
This expertise is crucial for manufacturing compaction tools and wear parts subjected to high thermal or mechanical stresses. We don’t just shape the material; we optimize the durability of your tools through perfect mastery of cutting and finishing processes on hard materials.
The nuclear market demands absolute rigor. To meet these requirements, AKRIS has developed a culture of “Zero Variability” and total traceability.
• Process traceability: Each machining step is documented, from the origin of the raw material to the final metrological control.
• Guaranteed repeatability: Our manufacturing protocols ensure that each part in a series, whether it is the first or the thousandth, scrupulously complies with the specifications.
• Non-destructive testing: We integrate advanced metrology phases to validate the conformity of each component before shipment.
Choosing the AKRIS Group means benefiting from the strength of a network. The harmonization of our systems (common ERP) allows for perfect synchronization of our workshops on an international scale.
This structure allows us to offer unparalleled capacity security: in the event of an overload at one production site, our other units can take over without any disruption to quality or delivery times. Your projects thus benefit from the flexibility of an SME and the industrial strength of a leading group.
To ensure the success of your complex projects, we rely on proprietary methodological tools such as Geogleiss and Vision 360. These infographics and processes allow us to visualize your constraints from all angles, anticipate manufacturing risks and co-create with you the most efficient and economical machining solution.
