Turning tools and turning methods for CNC machines

摘要

The cutting tool (1) for turning comprises a coupling part (4), an intermediate part (5) and a cutting part (2), the intermediate part (5) extending between the coupling part (4) and the cutting part (2). ), the intermediate part 5 extends along its longitudinal central axis A1, the cutting part 2 comprises first and second nose parts 10, 10', and a first nose The portion 10 comprises a first cutting edge 11, a second cutting edge 12, and a convex nose cutting edge 13 connecting the first and second cutting edges 11, 12, and The first and second cutting edges 11, 12 form a nose angle α of less than 90°, the longitudinal central axis of the coupling part 4 defines the tool rotation axis R1, and the middle part (5) extends along its longitudinal central axis (A1), the cutting part (2) comprises a top surface (7), the top surface (7) facing away from the coupling part (4), and the first And the second nose portions 10, 10' form the free ends of the cutting tool 1, respectively.
