Alsameca from the French town of Lutterbach has made a name for itself in these industries with high-quality cutting tools. When it comes to finding solutions for special cutting applications, the company works closely with the coating expert Cemecon — for example in the field of diamond-coated cutting inserts.

Anyone who enters Alsameca’s production facility in Lutterbach is immediately struck by the ultra-modern machinery, in addition to the cleanliness and obvious love of order. Automated grinding centers, robot-controlled test benches, optimized production management — the manufacturer of precision tools and regrinding service spares no expense or effort to ensure the quality of its products and at the same time a rapid responsiveness. The goal is to “increase our productivity, gain market share and remain competitive,” says Pascal Guichard, founder and director of the ASP group, which includes Alsameca. To achieve this, he is constantly investing in automation and digital technologies. In 2008, Alsameca joined the ASP (Affûtage Service Performance) group with a total of 49 employees. ASP is known for its versatility in grinding and in the production of cutting tools and wear parts (solid carbide, brazed carbide or high-speed steel).

Alsameca has been grinding precision tools for 42 years — today with 19 employees around 140,000 tools annually — and has already designed many sophisticated solutions for a wide range of industries. Thus, the experts know exactly how important the interaction of substrate, cutting-edge geometry and coating is. That is why ASP also has its own PVD coating expertise in-house and uses it successfully mainly for standard tools. For precision tools for special applications, when first-class premium coatings are required, Alsameca additionally relies on the experience of Cemecon.

Machining lightweight materials with diamond-coated cutting inserts

Alsameca cutting inserts score with exceptional cutting-edge geometries, multi blade configuration and high feed rates. “With their nanocrystalline, extremely smooth and hard surfaces, our CCDia coatings are superior to other coating solutions in terms of performance, quality and precision and contribute significantly to even higher efficiency. Especially on cutting inserts for machining CFRP and GFRP, graphite, non-ferrous metals or plastics, CCDia coatings open up enormous potentials,” says Jean Cariolini, Sales Europe at Cemecon. The powerful combination of Alsameca’s cutting inserts and Cemecon’s diamond coatings achieves excellent results when machining lightweight materials for the automotive and aerospace industries.

Matching all the parameters in a joint engineering approach of Cemecon and Alsameca made this happen. The experts coordinate the coating precisely with the requirements and application in a close dialogue. Substrate, geometry and coating all together form an optimal machining solution for the respective application — perfect for Alsameca’s sophisticated tool concepts and special applications.

Service life significantly increased

Stéphane Kalt, Director of Alsameca: “Whether dedicated diamond coatings for our cutting inserts or high-performance HiPIMS coatings for special applications — we have already worked with Cemecon in many successful engineering projects and are always very satisfied with the results and with the speed of implementation. With Cemecon’s diamond coatings, for example, we have been able to significantly increase the performance of our cutting inserts — both in terms of tool life and machining quality.”
