Abstract
A method is disclosed for cold-form profiling cylindrical, thin-walled hollow parts (1), comprising profiles (4) which extend in an essentially parallel manner in relation to the longitudinal axis (A) of the hollow part (1). At least one profiling tool (5) engages in a strike-like hammering manner with the outside of the hollow part (1) in a radial manner in relation to the longitudinal axis (A) o the hollow part (1). The profiling tool (5) engages, respectively, in an essentially vertical and oscillating manner on the surface of the hollow part (1). Then, the profiling tool (5) is displaced in an axial manner in relation to the hollow part (1) at a constant radial adjusting depth until the desired profile length is obtained.
