    摘要： The invention relates to a side milling cutter with cutting inserts (9), by which means a crank pin (2) can be cut with a single feed motion. The plate-shaped cutting inserts (9) are arranged on the periphery (7) of the inventive side milling cutter (1), alternating between the left and right side in a peripheral direction (8), and are oriented essentially radially with their cover surfaces (10) in relation to the cutter axis, said cover surfaces (10) containing the tool faces. The cutting inserts (9) are also arranged so as to form a gap (12) on the periphery (7) of the cutter (1) which is so narrow that the length of the arc of action (13) between the point of entry and the point of exit of cutting is greater than the half of the gap (14) of the arrangement of cutting inserts (9) on the periphery (7) of the cutter (1). The invention also relates to the configuration of the cutting inserts as indexable inserts which can be used on the left and on the right.

    摘要： A dual tip cutter (10) includes a body (12) defining a feed direction (F), a cutting direction (C) perpendicular to the feed direction, and a depth direction (D) perpendicular to both feed and cutting directions. A first cutting portion (35) is fixed relative to the body at a body first end. A second cutting portion (45) is fixed relative to the body at the body first end, adjacent the first cutting portion. The first and second cutting portions are stacked in the cutting direction so that the first cutting portion forms a leading cutting portion and the second cutting portion forms a trailing cutting portion for simultaneous cutting. The second cutting portion extends from the body further in the depth direction than the first cutting portion. A relative position between the first and second cutting portions is set such that a total chip load is shared between the first and second cutting portions in a predetermined ratio (K).

    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).

    摘要： An aspect of the present invention provides a cutting insert (10) including two first cutting edges (30, 32) with a curve shape on a first end surface (12) side and two second cutting edges (34, 36) with a curve shape on a second end surface (14) side, which is located opposite the first end surface (12). Each of the first cutting edges (30, 32) is formed on an intersecting ridge portion between the first end surface (12) and a corresponding side surface portion (20, 24) so as to curve in a direction orthogonal to an axis A extending so as to penetrate the first and second end surfaces. Each of the second cutting edges (34, 36) is formed on an intersecting ridge portion between the second end surface (14) and the corresponding side surface portion (20, 24) so as to curve in the direction orthogonal to the axis A.
