Method for production of external groove such as nozzle adjusting nut of rotary unit, involves generating external grooves by cutting shock process, so that tool is moved in extension direction of external grooves for cutting removal

摘要

The method involves producing the nozzle clamping nut (201) having a groove outer geometry (210). The through-chipping material removal on a contour (230) of the rotary unit (200) is performed. The rotary portion of the blank is provided. The external grooves (211) are generated by a cutting shock process, so that the tool (150) is moved in the extension direction of the external grooves for cutting removal. An independent claim is included for device for production of external groove of rotary unit.
