Graebener® is a medium-sized, family owned machine building company with locations in Netphen (Germany) and Houston (USA) as well as a variety of international representatives. Based on more than 100 years of experience in the metal processing business we develop and realize customized solutions for the core markets of automotive industries, hydroforming, manufacturing of large pipes, shipbuilding, wind tower production, vessel construction and hydrogen. Our product range includes hydraulic forming machines, milling and bending machines, calibration and straightening presses as well panel production lines. In addition, we have been one of the first companies to focus on the research and development of manufacturing processes and machines for fuel cell and electrolyzer components, such as metallic bipolar plates and stacks. With our business unit Graebener® Bipolar Plate Technologies, we have dedicated ourselves to setting the quality standard for these manufacturing technologies. To achieve this, we develop innovative processes that help to manufacture components for hydrogen-based energy generation that are tailor-made, integrable, scalable and thus economically efficient. Graebener® stands for a holistic approach. We are a technology and equipment partner and accompany our customers along the entire process chain from the initial idea, comprehensive engineering (including hydraulics, automation and control technology as well as intelligent Industry 4.0 applications) up to customized new machines or retrofitted existing ones.
Suitable for a wall thickness of up to 150 mm Pre-bending of conical shell sections is possible Deflection compensation over the entire pre-bending length of 4 m Automated positioning device for the plate handling during the pre-bending process
Highly flexible, reliable and economic: Graebener® pipe bending presses provide you with the decisive competitive edge in the production of LSAW pipe between 16 and 64 (406 - 1,625 mm). Benefit from our experience and the special characteristics of the Graebener® technology especially when it comes to increased wall thickness up to 75 mm and special requirements. Be different than the standard.
Our 3-roll bending machines are based on more than 40 years of experience in bending technology. Benefit from our individual concepts especially for shells of increased length and wall thickness. Irrespective of whether to be formed conically or cylindrically. Suited for increased wall thicknesses Economic production of cones without damage to the longitudinal plate edge Increased stiffness of the tilting bearing column Top roll inclination so that the pipe shells can be removed
Our 4-roll bending machines differentiate from the standard when it comes to the production of large vessels, wind towers and monopiles with increased wall thickness. We have specialized on types of applications which require a continuously high production output and quality from the machines even at a wall thickness of up to 200 mm. Corresponding to this, the Graebener® roll bending machines have a robust and long-lasting design.
Our market leading circ seam milling machines ensure the cost-efficient, reliable and safe weld seam preparation of extremely narrow welding gaps and are also suitable for the quick and reliable seam repair. In addition to rail-bound systems, we also offer mobile solutions transportable by crane, forklift truck or SPMT.
Our long seam milling machines (underground a. overground designs) are equipped with an intelligent copying system which compensates the height difference in case of uneven pipe supports. This way, we ensure a constant seam depth at any time. Quick and economic operation with milling speeds of up to 1,000mm per minute and cost-efficient milling tips with multiple cutting edges. The operator-friendly and accurate seam tracking is carried out by means of an integrated camera and laser pointer at the control screen.
Our plate edge milling machines operate with high precision, fast and reliable even under the most difficult conditions and after years of operation. We offer plate edge milling machines individually tailored to your requirements in a wide range of possible designs, e.g. with slewable milling head, moveable clamping beams or as tandem system. Our solutions are ideally suited for a wide range of plate dimensions: plate length up to 30 m, wall thickness up to 150 mm, individual plate weight up to 100 t.
