    摘要: A cutting tool includes a cutting insert having an anti-rotation stopping indent formed in a transition between a bottom surface and a side surface thereof and includes a first stop surface. The insert seat has at least one anti-rotation stop, which protrudes with respect to a side wall of the insert seat and includes a second stop surface. The anti-rotation stop is arranged to inhibit rotation of the cutting insert in the insert seat by contact between the first and second stop surfaces. The second stop surface is completely located within the anti-rotation stopping indent when the cutting insert is mounted. As seen in a section perpendicular to a common central axis, an angle of less than 180° is formed between a tangent to the second stop surface and a tangent to the first duct at a transition between the two.

    摘要: The invention concerns a cutting insert comprising an upper and a lower surface and one or more edge surfaces which connect the upper surface and the lower surface together, wherein provided at the transition of at least one edge surface at least to the upper surface is at least one cutting edge, wherein the upper surface adjoining the cutting edge is in the form of a chip surface and the edge surface adjoining the cutting edge is in the form of a tool flank. To provide a cutting insert in which the chip break range is enlarged and the risk of damage to the cutting insert and/or the tool and/or the workpiece by coiling chips is reduced it is provided according to the invention that at least one recess is provided in the tool flank at a spacing from the cutting edge.

    摘要: A rotary cutting tool includes a cutter body having a plurality of insert-receiving pockets. Each pocket includes a bottom support surface, an axial support surface, a radial support surface, a top clearance surface and an intermediate clearance surface extending between the axial support surface and the top clearance surface. A cutting insert includes a helical top surface, a helical side surface, a side surface opposite the helical side surface, a pair of opposed side walls, a bottom surface, and a cutting edge formed at an intersection between the helical top surface and the helical side surface. The cutting insert further includes an undercut for accommodating the axial support surface, the top clearance surface and the intermediate clearance surface of the pocket when the cutting insert is mounted in the pocket.

    摘要: An indexable cutting insert for face milling with high feed rates has: an upper side, a lower side with a smaller outer circumference than the upper side, and side surfaces connecting the upper and lower sides. Rounded cutting corners are formed at the transition between the side surfaces and the upper side. The cutting corners are connected via convexly arched cutting edges, each running convexly curved from one cutting corner to an adjacent cutting corner. Adjacent the cutting edges, the side surfaces have main flanks extending along the respective cutting edge in a continuously convexly curved manner from one cutting corner to an adjacent cutting corner. The main flanks extend in the direction of the lower side only over part of the height of the side surfaces and merge in a stepped manner into secondary surfaces which are set back inward.
