A double-sided milling cutting insert has two plane-parallel, equal chip or main surfaces (2), which are turned 90° relative to each other. Each main surface comprises four operative cutting corners. In connection to each cutting corner are two bevelled surfaces (5, 6) which are angled relative to the plane of the main surface. The four side surfaces (3) are pairwise angled in order to make possible a positive cutting geometry. By the two bevelled surfaces (5, 6) the occurrence of edge chippings in the work-piece has been considerably reduced.
Une plaquette de fraisage double face comprend deux surfaces (2) principales ou à copeaux, similaires et à plans parallèles, qui sont tournées de 90 ~ l'une par rapport à l'autre. Chaque surface principale comporte quatre coins tranchants opérants. En relation avec chaque coin tranchant, la plaquette comprend deux surfaces en biseau (5, 6) formant un angle par rapport au plan de la surface principale. Les quatre surfaces latérales (3) forment des angles par deux afin de permettre une géométrie de coupe positive. Les deux surfaces en biseau (5, 6) permettent de réduire considérablement la formation de copeaux au niveau des arêtes de la pièce à usiner.
