CUTTING INSERT AND CUTTING TOOL ASSEMBLY WITH CUTTING INSERT FOR MACHINE-TOOL AND TOOL HOLDER FOR SUCH CUTTING TOOL ASSEMBLY WITH CUTTING INSERT

摘要

The insert blade (10) has an upper surface (12) bounded by a cutting edge (14), a lower portion (16), a slate portion (18) and a one-axis of symmetry. The cross section of the slate portion (18) is perpendicular to the axis (12) in a plane perpendicular to the upper surface (12) and has a non-concave shape without circumferential recesses. The section (18) has a rotationally symmetrical cross-sectional plane in the plane (s) perpendicular to the lower portion (16), having a number of outermost points of at least three and asymmetrically extending adjacent outermost points Suitable concave support surfaces (38) forming a substantially star-shaped cross-sectional profile. The die body of the cutting tool has at least one slot for receiving the insert blade (10). The nest is provided with a lower bottom surface which abuts the face of the lower portion (16) of the inserted blade (10) and has a star-shaped cross-sectional section 38 having a star-shaped cross-section 38 having a nozzle (10) ) the support surfaces of at least two torque transducers formed at a right angle. ŕ
