  • Gräbener Maschinentechnik: Impressive and exemplary
    pipe and vessel production can be accelerated and made more efficient by our machines Only one reason why these machines have become a standard for the leading processors of thick plates worldwide However Dr Gräbener stated explicitly that top quality machines which make a lot of money also attract imitators Companies in Austria Finland and China are already copying our machines A Chinese company even advertises its seam milling machines with the slogan German Technology There are also some competitors in the other sectors where Gräbener Maschinentechnik is the market leader production lines for ship deck sections machines for the pipe and wind tower production as well as hydroforming presses In the sector of production lines for ship deck sections we are surely the global market leader explained Dr Gräbener In 2001 Gräbener Maschinentechnik revolutionized the shipbuilding sector together with the shipyard Meyer Werft by building a fully automated Tailor Welded Plates system With this TWP system and using the laser hybrid welding technology individual plates of various thicknesses are joined to customized ship deck sections of up to 400 m² Prior to this process Gräbener plate edge milling machines are used for the preparation of the welding edges Gräbener was able to book further orders from other shipyards increasing the possible ship deck section to be joined to a size of up to 750 m² Using the know how gained from the former production of large pipes as Gräbener Großrohr Gräbener Maschinentechnik today is able to supply all production machines for the manufacturing of longitudinally welded pipes from plate edge milling machines to pipe forming presses and finally up to impanding and straightening presses In the offshore wind sector we are the only system provider for machines Dr Gräbener added Gräbener Maschinentechnik has already supplied internationally renowned market leaders

  • Gräbener Maschinentechnik: The optimized weld seam preparation
    long seam milling machines for the production of the narrow gap for UP weld seams With these machines it is possible to accelerate the production and make the process more efficient even in pipe and vessel construction a sector that is dominated today by high technology Ever increasing yield strength and quality like X80 require that the tacking lay of the slit pipe has to be removed beyond the root pass As quality and cost of a weld seam depend on seam type and volume Graebener is specialized in processing the optimized seam geometry Especially during the welding of higher grade materials with high yield strengths the CO2 tacking lay has to be worked out up to the root layer if you want to avoid welding mistakes Since Graebener made this experience as manufacturer of LSAW pipes until 1997 the company group already developed the circ and long seam milling machines in the beginning of the 1980 s These machines remove the tacking lay with the help of a side milling cutter and have become standard at the leading thick plate operators worldwide Comparing to the grouting with carbon rods and grinding only advantages are given the costs per meter welding seam can be reduced in part by more than 50 percent shorter processing time of the seam preparation reduction of welding material needed reduction of welding time and a considerably lower energy consumption the surface quality is higher and the geometry of the seam volume is more regular Furthermore the subsequent welding process can be automated the working conditions are improved and the chips which occur during the milling can be recycled Considering the enormous advantages which arise from the seam milling technology it is no wonder that the circ and long seam milling machines of Graebener have found

  • Gräbener Maschinentechnik: Amazing and superior technological solutions
    has become even more important since Reika together with the customer conducts tool tests and further developments with the machines available at the demonstration center especially with the machines of the RingSaw series Managing Director Hans Jörg Braun is certain that this is the best way for Reika to learn and determine which tool is most suitable for the customer s material thus leading to optimum results The customer simply supplies the material and does not need to assign any of his own machines for the testing process which would impact his production On the other hand this is also an ideal way to convince the customer of the superior qualities of our RingSaw technology This goal was already met during the open house event Even though customers already knew the RingSaw they were still amazed at the features of the machine series for the cutting of tubes profiles and bars and for various applications concerning the separation of tubes and bars The cut is almost free of burrs and the tool costs are significantly reduced in comparison to conventional hard metal saws while at the same time speeding up the performance Hans Jörg Braun That is the major advantage of our demonstration center Here the customer can experience the features of our machines directly under most various conditions with different materials While Reika presented their vast experience with the cutting and processing of precision tubes Gräbener showed their abilities at the Quartier Landeskrone with machines of completely different dimensions The two 4 roll bending machines currently being assembled there are nearly ready to the shipped to a manufacturer of offshore monopiles They are used for bending plates with a wall thickness of up to 150 mm to individual pipe sections with a diameter of up to 10 m These

  • Gräbener Maschinentechnik: Graebener exhibits fuel cell vehicle at the Hanover Fair
    battery driven vehicles Range extenders can increase the possible range of battery driven vehicles to up to 500 km by continuously recharging the battery In the current vehicle concept this is achieved by using a generator which however produces air pollutants and noise negating the advantages of battery driven vehicles to some extent A hydrogen powered fuel cell however which works with next to no noise and only emits water steam preserves these advantages The project consortium consists of the partners Institute for Combustion Engines VKA at the Technical University RWTH Aachen module development the company FEV Motorentechnik Aachen development of complete systems and their integration into vehicles the Center for Fuel Cell Technology in Duisburg development of fuel cells and the company Graebener Maschinentechnik production of metal separator plates for fuel cells The continuous efforts of the company Graebener to promote research and development in the fuel cell sector were one of the reasons that the vehicle can now be presented to the public for the first time The project has an overall budget of approx 2 5 million Euro and will be sponsored with 2 million Euro by NRW within the framework of the initiative Electric Mobility NRW
