SCHNEIDEINSATZ

摘要

The invention relates to a cutting insert for cutting machining, especially for the coarse machining of metal workpieces at high feed rates. To improve the flow of chips during cutting, it is proposed that the indentations (14) in a cross-section parallel to the cutting edge (12) and perpendicular to the cutting surface (10) form a trapezoidal recess, the sides (25) of which are open towards the cutting surface (10, 16), the cutting surface base (18) running towards the cutting edge at a cutting angle which is negative or 0 DEG , and the cutting surface (16) making a positive cutting angle (17) with the cutting edge (12) in the region between the indentations (14).
