Abstract: A method is provided for smoothing a surface region of a component consisting of an electrically conductive material. The surface region of the component is coated inside a vacuum chamber, by focused electron beam(s) with a first surface energy, which brings about melting of the component material within the surface region. Before melting, the surface region is passed over at least twice by the electron beam, each time with a different focal length of the electron beam. A second surface energy is set for the electron beam, such that no melting of the component material is brought about in the surface region. Data is recorded by a number of sensors arranged inside the vacuum chamber. An actual value for the roughness is compared to a set point value. If the actual value has not reached the set point value, a value for the first surface energy is determined via comparison.
