Akris Group > Our expertise > Grinding & Surface Finishing
In the world of high-precision mechanics, machining is often only the first step in a complex process. The true added value, the one that guarantees the longevity of a compaction tool or the reliability of an aeronautical component, lies in the mastery of grinding and surface finishing. Within the AKRIS Group, we consider these technologies to be the pinnacle of our expertise.
The fusion of our expertise under the akris-group.com entity allows us to offer our clients a complete value chain, where each brand brings its technical specificity. Whether for cylindrical, profile, or coordinate grinding needs, our workshops are synchronized to meet the most extreme tolerances on the market.
Grinding is a critical abrasion process that makes it possible to achieve surface finishes and dimensional accuracy impossible to obtain by conventional machining. The AKRIS Group has invested heavily to cover all industrial needs :
• Cylindrical grinding ( internal and external ) : indispensable for parts of revolution, this technology ensures perfect concentricity and micron-level precision. Our capabilities allow us to process components of various dimensions, thus meeting the needs of the mobility and energy sectors.
• Profile and prismatic grinding : we operate on complex geometries where every angle and every radius must perfectly conform to the client’s drawing. This expertise is particularly sought after for the manufacture of industrial tooling subjected to high stresses.
• Coordinate grinding : this is where ultra-precision takes on its full meaning. Used to position bores or shapes with absolute accuracy, coordinate grinding is a niche technology that we master perfectly within our expert sites.
One of the major strengths of the AKRIS Group lies in the integration of disruptive technologies. The recent acquisition of PEEL (Pe Grinding) technology is a perfect illustration of our commitment to staying at the forefront of innovation.
Rather than simply investing in an additional machine, the group made the strategic choice to acquire a complete unit mastering this high-performance grinding technology. PEEL grinding (Peel Grinding) allows for exceptional material removal rates while maintaining extreme precision and irreproachable surface quality. It is an ideal solution for complex parts requiring a perfect compromise between productivity and ultra-precision.
Beyond geometry, a part’s surface finish directly influences its mechanical properties : reduced friction, corrosion resistance, or even biocompatibility in the medical sector.
• Precision polishing : our expert technicians perform highly controlled polishing to guarantee minimal roughness.
• Mirror finish : for the most sensitive applications, we are capable of achieving a mirror finish, guaranteeing absolute surface purity.
• Specific surface treatments : In addition to grinding, we support our clients in the choice and application of surface treatments adapted to their operating environments (thermal, chemical, or mechanical).
For the nuclear and defense markets, grinding and finishing are not only technical, they are regulatory. The AKRIS Group meets these requirements with a strict “zero variability” approach.
Each grinding operation is subject to rigorous monitoring. The repeatability of our processes guarantees that each part delivered is the perfect clone of the previous one, an absolute necessity for safety-critical components. Our traceability protocols allow us to track every stage of manufacturing, ensuring total transparency for our contractors.
Choosing AKRIS for your rectification needs means relying on the strength of a structured group. Thanks to the harmonization of our systems (common ERP), we manage the workload of our workshops globally.
If a production site like Sumca or S3M encounters a capacity overload , our other units can take over in total transparency for the client. This capacity security is a major strategic advantage : we guarantee the respect of your deadlines without ever sacrificing the quality that makes the reputation of our brands.
For each complex project, we provide you with our methodological tools such as Geogleiss and Vision 360. Ces outils nous permettent d’analyser vos besoins de rectification sous tous les angles techniques et économiques, pour vous proposer la solution de finition la plus adaptée à vos enjeux de performance fonctionnelle
