Abstract:
1. An apparatus for at least one chosen from surface strengthening and smoothing of an integrally bladed rotor of a jet engine, comprising: a container filled with at least one chosen from non-abrasive strengthening and smoothing elements to a specified height, the at least one chosen from non-abrasive strengthening and smoothing elements having, at least in some areas, a spherical form; a device for holding the rotor inside the container to which the rotor can be connected, the device constructed and arranged to hold the rotor in a position inside the container equivalent to an at least approximately horizontal orientation of a rotary axis of the rotor; a rotation drive unit by which the rotor can be set into rotation in its position inside the container equivalent at least approximately to the horizontal orientation of the rotary axis, wherein the specified height is sufficient to contact an entirety of the rotor as the rotor rotates in the container; a vibration drive unit for vibrating the strengthening and smoothing elements positioned around the rotor in its position inside the container equivalent at least approximately to the horizontal orientation of the rotary axis, the vibration drive unit and rotation drive unit creating a relative motion between the at least one chosen from non-abrasive strengthening and smoothing elements and the rotor to at least one chosen from strengthen and smooth the rotor in a non-abrasive manner without material removal.
