摘要

The milling cutter (15) is circular and consists of several metal disks (21a-e) side-by-side. The edges of the individual disks are narrowed in steps (24-26) and there are milling cutters (27) at the edge. There are pairs of cutters (28a-31b) at the shoulders or steps in thickness, cutting and widening parallel grooves in the root of the turbine blade (2).
