CUTTING INSERT FOR CHIP FORMING MACHINING

摘要

The invention relates to a cutting insert for chip forming machining, primarily for milling. The insert has an upper face (11), a lower face (12) and edge faces (13-16) therebetween. The upper face (11) is provided with a number of depressions spaced apart, said depressions (21) having a longitudinal extension in a direction that forms an angle ( alpha ) with a line perpendicular to the adherent cutting edge (18), said angle ( alpha ) being in the interval 5 DEG - 45 DEG . By this design a low wear of the cutting edge and consequently longer life even at higher temperatures can be achieved.
