    摘要： The invention relates to a tool that is intended for cyclo-palloid gear hobbing and includes a head (1) and a plurality of milling inserts (2) protruding from a front side (4) of the same. The milling inserts are mounted - suitably two by two - in chip removal units (3) that are detachably connected to the head. The individual milling insert (2) is clamped by means of a wedge (19) and a screw (20) easy to access, the wedge (19) acting tangentially against the milling insert behind which there is a robust tangential support in the form of a shoulder (56). By said wedge clamping of the milling insert, there is gained that the milling inserts can be mounted and dismounted in a simple way, as well as that each group of wedge+milling insert+tangential support can be located tangentially and thereby efficiently carry the cutting forces acting on the milling insert. In further aspects, the invention relates in addition to an insert holder as such intended for the tool, a chip removal unit in the form of an insert holder equipped with a milling insert, as well as an insert kit.

    摘要： A cutting insert according to an embodiment of the invention includes: an upper surface; a lower surface; a side surface which is connected to each of the upper surface and the lower surface, and includes a first side surface and a second side surface adjacent to each other; and a cutting edge including a major cutting edge located at an intersection of the upper surface and the first side surface, and a minor cutting edge located at an intersection of the upper surface and the second side surface. The upper surface includes a rake surface which is located along the major cutting edge, and is inclined downward as the upper surface separates from the major cutting edge. The second side surface includes a second upper constraining surface and a second lower constraining surface in order as the second side surface goes from the upper surface to the lower surface. The second upper constraining surface is inclined inward at an inclination angle ±1 with reference to a central axis extending between the upper surface and the lower surface. The second lower constraining surface is continuous with the second upper constraining surface, and is inclined outward at an inclination angle ±2 with reference to the central axis.

    摘要： A cutting insert having excellent chip discharge performance is provided. In the cutting insert of the present invention, a bottom surface of a concave groove 21 includes a first bottom surface 211 continuous with a cutting edge part 5, and a second bottom surface 212 which is located on a side further remote from the cutting edge part 5 than the first bottom surface 211, and is located at a lower position than a virtual extension line L1 of an end portion of the first bottom surface 211 on a side remote from the cutting edge part 5. Further, a pair of inclined surfaces 23 are located on a side further remote from the cutting edge part 5 than the end portion of the first bottom surface 211 on the side remote from the cutting edge part 5 in a top view. Therefore, the diameter of generated chips decreases by the fact that the chips are curled while sinking in space formed at a lower position than the virtual extension line L1 of the first bottom surface 211. Consequently, the chip discharge direction is stabilized, thus achieving satisfactory chip discharge performance.

    摘要： An indexable cutting insert (10) has mutually perpendicular longitudinal, lateral and vertical axes (A, B, C). The insert includes two opposite cutting portions (106, 108) and a clamping portion (112) therebetween, arranged parallel to the longitudinal axis (A). Each cutting portion 106, 108) includes a rake surface (114) and front and side relief flanks (116, 118), and a cutting edge (120) formed at an intersection of the rake surface (114) and front relief flank (116). A second width (W2) of the clamping portion (112) is greater than the first width (W1) of the cutting edges (120) . The clamping portion (112) has two resilient beams (125) and a flexibility aperture (124) opening out to side abutment surfaces (123, 124) of the clamping portion (112), allowing elastic deformation of the insert (10) along the vertical axis (C). The cutting insert may further include two opposite stopper portions (126), each formed on a respective insert end surfaces(102), each stopper portion (126) forming a step in the respective insert end surface (102). A cutting tool (150) clamps one or more inserts (10) at their clamping portions (112).
