The rotor (1) has a profile, which is fabricated in a spatial cutting-turning process, using a plunging tool (3) to cut a gr with rectangular cross section, and a special tool to form left and right profile flanks. The tools are clamped in a holder (2), which is set to the average pitch angle of the rotor to be fabricated, on a rotary axis, which cuts across the blank axis. In a first stage, the groove is cut and in a three-way process, and in following stages, the groove is cut deeper to give a depth of a few mm, the profile flanks are cut in a two-way process using the special tool. The plunging tool is used to further increa the groove depth. |
