Unit for deburring and rounding edges in a surface grinding machine

An edge machining assembly for a wide grinding machine, comprising:

• a plurality of cylindrical roller brushes, each cylindrical roller brush of the plurality of cylindrical brushes having a respective cylindrical surface and a multiplicity of brush elements on the respective cylindrical surface, wherein each cylindrical roller brush has a respective first axis of rotation which corresponds to a center longitudinal axis of the cylindrical roller brush,
• a first drive unit configured for driving each cylindrical roller brush in a rotational movement about the respective its first axis of rotation of each respective cylindrical roller brush,
• a plurality of holders, wherein each cylindrical roller brush is mounted in a respective holder of said plurality of holders, wherein each respective holder has a respective second axis of rotation, wherein each respective second axis of rotation is not aligned parallel to the respective first axis of rotation, wherein each cylindrical roller brush having a respective first axis of rotation is mounted so as to be rotatable about the respective second axis of rotation of the respective holder in which the respective cylindrical roller brush is mounted,
• a second drive unit configured for rotating each cylindrical roller brush having a respective first axis of rotation about the respective second axis of rotation of the respective holder in which the respective cylindrical roller brush is mounted,
• a plurality of suspension frames defining a third movement axis, wherein each respective holder having a respective second axis of rotation is mounted to one respective suspension frame of the plurality of suspension frames, wherein each respective suspension frame is guided for a movement guided by the third movement axis,
• a third drive unit configured for moving the plurality of holders having respective second axes of rotation in a movement guided by the third movement axis,
• wherein the third movement axis is in the form of a closed guideway, and each holder of the plurality of holders having a respective second axis of rotation is moved along the closed guideway by the third drive unit.
