One process fits all?

The edge rounding of hard metal tools is an established process to extend the service life of tools and to improve the adhesion of PVD layers. The rounding and smoothing of the cutting edge reduces the risk of micro-breakouts and significantly increases the mechanical stability of the cutting edge. These are the clear processing goals.

Would you wear your old favorite wool sweater any time of the year or any occasion because it is the most comfortable solution? Probably not. It is the same when rounding the cutting edge of hard metal tools. The most convenient solution is rarely the best for the best result. The "one process fits all" approach would be just as fatal for your tools as wearing your wool sweater in midsummer.

The scenery is certainly attractive, because a single machining process fits all tools such as drills, milling cutters, reamers, preferably across all tool dimensions. Practice shows that it is a bit more complex: a good and professional edge rounding depends on many factors, such as area of application, material, geometry, etc. With uniform processing, the process would occasionally fit by chance, but often not.

Each tool must be considered individually, tailored to each of your tools, the subsequent application and the production-related framework conditions. Each type of tool requires a specific machining process. Process reliability, repeatability, economic efficiency and, above all, quality can only be guaranteed with individually developed processes. If individual processes are then automated, you will receive quality "non-stop"!

With the stream finishing machine SF-1-ILS, OTEC offers a solution for flexibly processing each tool individually, at the same time quickly and, above all, automatically with a reliable process.
