  • Method for smoothing a surface of a component
    Patent number: 11612977
    Abstract: The present invention relates to a method for smoothing a surface of a component, in which a component is placed in a liquid-solids mixture; a relative movement is produced between the liquid-solids mixture and the component; thus there is a flow of the liquid-solids mixture along the surface; wherein there is provided in the liquid-solids mixture a guide surface, along which the liquid-solids mixture flows, wherein a directional component toward the surface is imposed on the flow.
    Type: Grant

  • Method of producing blades or blade arrangements of a turbomachine with erosion protection layers and correspondingly produced component
    Patent number: 10400613
    Abstract: The present invention relates to a method for producing a blade or blade arrangement of a turbomachine, which features the following steps: producing a blade (4) from at least one blade material, machining the blade in at least one region of the blade by a surface machining process, cleaning the surface of the blade depositing an erosion protection coating (10) of at least two layers of different hardness by physical vapor deposition in the at least one region, machining the erosion protection coating (10) by a coating smoothing process in order to establish a defined surface roughness. Furthermore, the invention relates to correspondingly produced blades or blade arrangements.

  • Method and device for machining robot-guided components
    Patent number: 9597799
    Abstract: A method for machining a robot-guided component with a tool which is fastened in an articulated manner to a tool holder is disclosed. The method includes detecting a deflection of the tool with respect to the tool holder from a desired position and changing a pose of a robot that is guiding the robot-guided component on a basis of the detected deflection.
