To manufacture keyway surfaces, plane surfaces or polygon profiles, we recommend polygon turning with the Schwanog system. Schwanog turning tools are available from stock for all common types of machines or equipment for polygon turning. Like all Schwanog systems, the cutting tools are also designed with exchangeable inserts. With the Schwanog system, the polygon is machined directly on the lathe in one process. The time-consuming changeover from turning to milling is eliminated. Polygon turning is significantly faster than milling, furthermore process reliability increases significantly due to the integrated production sequence on one machine and costs are reduced consider.
