The DIAMETAL group unifi es three main fi elds of expertise III and high-precision industrial know-how that has been constantly evolving since 1936. DDifferent from its history and its rich experience, the group provides the international market with standard or high-precision solutions personalized in three strong fi elds III.DIAMETAL delivers its production secrets (expertise, tools, methods, parameters) and even the fi rst tools to its customers. It‘s simple and it really makes the Difference.

DIAMETAL Group Swiss Cutting Tool

Precision tools for gear hobbings

Your specialist for high quality applications

and it really makes the DDifference.

Excellent servicein application and processes

QualityIn order to guarantee a long service life of its hobs, DIAMETAL uses the best carbide grades and the most suitable coatings for your applications. We are able to guarantee process repeatability and consistent profi le machining. Our production, which complies with current quality standards, is continu-ally adapted to meet your needs. A systematic check is carried out before each delivery and on request, our gear hobbing tools can be supplied with an inspection report.

SimulationDeviations between the theoretical and actual tooth geometries are quickly calculated and detected when designing the micro gears.DIAMETAL "Virtual Gearing" simulation guarantees short cycle time and maximum process repeatability. We offer individual solutions. Every cutter de-sign is simulated in order to virtually check the tooth profi le created by the cutting process and thus guarantee the application.

Sharpening the gear hobsThe lifetime of a hob depends largely on its sharpening process. The burr formation, deteriorating surface fi nish and a deformed profi le are factors indi-cating that the tool needs to be reground. We offer a sharpening service for all types and sizes of hobs with the possibility of adapting or changing the cutting angle according to your needs.

Logarithmic reliefAll gear hobbing tools of DIAMETAL Swiss Cutting Tool are ground with a logarithmic undercut, guaranteeing the exact shape of the profi le after each sharpening.
