65mm Plate Welding Groove Opening Machine

Graebener Plate Welding Groove Opening Machines

For excellent welding performance, the preparation of the plate welding groove opening must be done accurately and precisely. Graebener® plate welding groove opening machines offer you the most effective and economical solutions to achieve the best results. Benefit from our technical expertise based on years of experience and master all welding groove geometries with high speed, precision, and reliability.

Overview

Graebener® welding groove opening machines are designed based on our long-standing technical expertise. You can benefit from the extremely comprehensive experiences we gained in our own pipe factory between 1974-1997 as our customer and partner. Thanks to this experience, we know that high precision in processing plate edges can only be achieved if the plates remain locked throughout the entire processing time. Especially with large format plates, your Graebener® plate welding groove opening machine will further increase economic efficiency in plate edge processing.

The main application areas are shipbuilding, wind tower construction, bridge construction, and ship and equipment manufacturing. Additionally, plate mills and steel service centers are also among our customers.

Compared to alternative plate edge processing methods, the advantages of milling technology are much greater. We fully utilize these advantages.

OUR SOLUTIONS WE OFFER YOU ARE EXTREMELY IDEAL FOR A WIDE VARIETY OF PLATE SIZES.

ADVANTAGES

All Graebener® plate welding groove opening machines have a proven design that operates reliably even under the most difficult conditions. We avoid using extra rotating devices that may be exposed to wear or failure. Even after years of use, your Graebener® machine will continue to operate with high precision, quickly, and reliably. Take advantage of the technical advantages of your Graebener® plate welding groove opening machine.

• The milling process does not cause additional stress on the plate due to heat - recyclable milling chips dissipate heat

• You achieve a metallic shiny surface

• High parallelism on milled edges

• You can benefit from our excellent plate clamping system:

  • High compatibility rate

  • Smooth welding groove opening

  • Less wear on milling tools

  • Less vibration

• Plates are automatically measured

• Low environmental impact due to low noise, dust, and heat emission

• Bevel breaking is also possible in addition to U-grooved seams

• Electronic copying of plate waves offers a center-focused milling profile

• Depending on the machine type, plates can be placed inside the machine, eliminating the need for a garage crane

• Depending on the design, you can also process cladding plates
