Abstract:
Milling cutter (1), which can rotate about a cutter longitudinal axis (A), comprises a sleeve-shaped shaft (2) provided with an inner lying chip evacuation channel (11), which is arranged, in essence, symmetric to the cutter longitudinal axis (A), and with a suction opening (12). The milling cutter also comprises a milling head (3, 3a, 3b, 3c), which is held coaxial to the cutter longitudinal axis (A) and to the shaft (2) while being held on said shaft and which comprises, as cutting edges (7, 9), a face cutting edge (7) and a peripheral cutting edge (9). At least one cutting edge (7, 9) forms a positive rake angle (′Ya,′Yr) on the periphery of the milling head (3, 3a, 3b, 3c). The milling cutter (1) is particularly suited for machining light metals, especially for circular milling.
