  • Ziesel, Norbert
  • Beig, Frank

Abstract

The invention relates to a device and a method for producing longitudinal grooves in cylindrical workpieces, especially for producing longitudinal grooves having an irregular profile. The forming process is carried out by means of segmental wheels in a similar manner to that of a rolling method.
