There are some challenges in the machining of buildup welded structures by milling. For a perfect surface, in particular, there must be no burrs that cannot be polished out later. “The floor under our robot contained a material that was slightly yielding,” reports Thomas Engel, project manager at spannverbund GmbH. This made machining by robot imprecise and not exactly reproducible. “So we tore out the entire floor under the robot and filled it with a flow filler, realigned everything and doweled the fixture, a huge effort until the robot stood exactly level and could work precisely.” The effort paid off. The surfaces can now be machined precisely and the result is impressive.
