When manufacturing large ship deck section so-called "stiffener" profiles are placed and welded onto the sections which serve for stabilizing the panels. To join the stiffener profiles by means of the laser or laser-hybrid welding process, the profile edges need to be prepared first. For this purpose, we have developed the Graebener® profile milling machines which reliably remove the rolling edges of the plates delivered from the rolling mill with a certain round shape.
Profile length (milling length):
3 - 30 m
up to 15 mm
bulb profiles (HP profiles)
angle steels even
angle steels uneven
Graebener® profile milling machines are no standard solution. As special machine builder we have be specializing for decades on machine concepts following the ever increasing requirements for quality of the weld seam preparation. These concepts are customized for your individual requirements as well the materials applied.
Graebener® profile milling machines are designed for the integration into a profile production line and works on the principle that the workpiece is moved through the machine instead of the milling head moving along the workpiece. This way, you can further transport the stiffeners after the processing in a fully automated stiffener fitter.
