Plate edge milling & beveling

The design principle of the Graebener plate edge milling machines is based on the experience that tight processing tolerances of the weld edges can only be guaranteed if the plates remain clamped over the entire processing length. The plate edge milling machines enhance effectiveness when large-format plates are processed, for example in shipbuilding, production of large pipes, wind tower production, pressure vessel/apparatus construction, plate rolling mills, steel service centers and bridge construction.

In particular, since the requirements on quality and the subsequent processing steps, such as welding, are ever increasing, the milling machines offer the following advantages:

  • no additional heat input
  • clean and metallic bright surface
  • high parallelism of the milled edges
  • constant root face on the entire length due to plates being clamped over the entire milling length
  • reduced wear of milling tips
  • recycling of metal chips possible
  • low environmental pollution (noise, dust, heat)
  • single U-groove seams are possible as well as chamfering
  • copying of plate waviness guarantees a constant welding root position
