摘要： The invention relates to a cutting insert having a polygonal upper side. Cutting edges, which are alternately configured as roughing cutting edges and finishing cutting edges, are provided at the edges of the upper side. The finishing cutting edges define an incircle (K1) having a diameter that is enlarged in comparison to a nominal size of the cutting insert, and the roughing cutting edges define an incircle (K2) having a diameter that is reduced in comparison to the nominal size of the cutting insert. The invention further relates to a cutting tool having a tool body on which at least one such cutting insert is disposed.

摘要： A double-sided milling cutting insert has a first cutting edge disposed at an intersection of a top side and a side surface and a second cutting edge disposed at an intersection of a bottom side and the side surface. Each of the first and second cutting edges contains three cutting edge portions which are useable by indexing. The cutting edge portions each have a cutting corner, a main cutting edge adjacent to one side of the cutting corner, and a wiper edge adjacent to the other side of the cutting corner. The main cutting edge and the wiper edge are each inclined towards a reference plane with increasing distance from the cutting corner such that the first and second cutting edges have the largest distance to the reference plane in the regions of the cutting corners. The side surface has main clearance surfaces, secondary clearance surfaces, and curved corner surfaces.

摘要： A cutting tool for face milling includes insert pockets for the fixing of cutting insert. The cutting inserts can be fixed in the insert pockets, wherein the cutting inserts and insert pockets are designed such that, when the cutting inserts are fixed within the corresponding insert pocket, each cutting insert presents: a primary and a secondary cutting edge. The intersection between the primary and the secondary cutting edge of one cutting insert being axially inwardly and radially outwardly offset from the intersection between the primary and the secondary cutting edge of another cutting insert. A lead angle defined between the primary and the secondary cutting edges is less than 30°.

摘要： A cutting insert has an upper surface, a lower surface, a side surface connecting the upper and lower surfaces. An intersecting edge between the upper surface and the side surface is provided with a cutting edge. The cutting edge has, in order, a second major cutting edge, a first major cutting edge, a corner cutting edge connected to these major cutting edges, and a flat cutting edge. An obtuse interior first angle (θ) is formed by the second and first major cutting edges. A interior second angle (α) formed by the flat cutting edge and the first major cutting edge is larger than an interior third angle (β) formed by the flat cutting edge and the second major cutting edge. A land is provided adjacent to the first major cutting edge, a width of the land increasing toward the first corner cutting edge.

摘要： A double-sided cutting insert for milling, in particular for face milling, includes first and second cutting edges each having alternately disposed main lips and secondary lips which each extend between active and passive cutting corners. Each main lip, starting from a first distance from a reference plane at an active cutting corner, extends in a manner dropping monotonously to a smaller, second distance from the reference plane at a passive cutting corner. That end of a secondary lip that adjoins the active cutting corner is in each case at a greater distance from the reference plane than the other end of the secondary lip that is remote from the active cutting corner. A circumferential side surface has, immediately adjacent the secondary lips, in each case planar secondary flanks and each secondary lip is formed at least regionally in a convex manner in plan view of the associated secondary flank.

摘要： A single-sided ramping milling insert for ramping operations has top and bottom surfaces and a peripheral surface which extends therebetween. The peripheral surface meets the top and bottom surfaces at respective top and bottom edges. The top edge includes two opposite side cutting edges, two opposite ramping cutting edges, two diagonally opposite raised corner cutting edges and two diagonally opposite associated lowered corner cutting edges. The lowered corner cutting edges are closer to the bottom surface than the raised corner cutting edges. The bottom edge has two diagonally opposite bottom corner edges. The lowered corner cutting edges and the bottom corner edges are convexly curved and a depression is recessed into the peripheral surface between each lowered corner cutting edge and its associated bottom corner edge, the depression configured for providing relief from a convex workpiece surface cut by the lowered corner cutting edge during ramping operations.
