  • Gräbener Maschinentechnik: High-precision measuring technology for high-precision hydroforming
    For Gräbener Maschinentechnik another vital feature of this highly specialized measuring technology is that the machine is suitable to verify complex surface structures even on shiny and reflecting surfaces Edelmann This would be next to impossible using traditional and conventional measuring technologies He is certain that Graebener will assume the pioneering role in this sector as well Since the 3D laser measuring machine used by Graebener among other features is

  • Gräbener Maschinentechnik: Open-heart surgery
    throughout the entire project During this retrofit which has been developed and planned in close cooperation of the two companies Eisenbau Krämer and Gräbener Maschinentechnik the entire hydraulic system including eight hydraulic pumps will be installed on a newly built platform at the outfeed side of the older pipe forming press Reservations concerning a possibly increased noise generation could be eliminated quickly since the hydraulic units are insulated in a way that the noise emission remains well below the valid limits This design has another major advantage elaborate piping can be reduced to a minimum so that the entire pre assembly can be carried out at the premises of Graebener This in turn reduces the time needed for the assembly at Eisenbau Krämer s workshop and therefore the period of production down time The tank with the hydraulic blocks will be installed at the new platform The tank mostly serves for accommodating the pendulum volume of the hydraulic cylinders It also allows a quick replenishing of the hydraulic fluid Just to give an impression of the dimensions we are talking about here The tank volume is approximately 24 000 liters All in all the new platform including the new electric control housed in eight control cabinets is subject to a total load of approximately 120 t Apart from the hydraulic system and the electric control the deflection compensation of the pipe forming press will be retrofitted as well The existing compensation cylinders inside the lower traverse will be replaced by wedge adjustments This will reduce manufacturing tolerances and ensure high production precision In the end the retrofitted pipe forming press will be on par with a new machine especially concerning the energy consumption which was seriously outdated with the old machine The retrofitted press uses the so called load sensing

  • Gräbener Maschinentechnik: Press becomes market reference
    the fact that the new press represents the latest technological standard in the sector of hydroforming and will certainly set a milestone in terms of dynamics and output One of the reasons for this outstanding performance is the new control system which allows an equipment of the press with a total of 32 controllable axes and four pressure intensifiers for the application of highly complex multiple tools With the combinable

  • Gräbener Maschinentechnik: Gräbener Maschinentechnik retrofits pipe mill
    SAW plant using the JCO process with a 6 000 t press Submerged Arc Welding Mechanical Expansion with capacity to produce API pipes from 20 to 60 diameter Tubacero acquired the company mid 2011 made an evaluation of its capacity and made a plan to improve quality and production capacity Tubacero asked Graebener for support and for this new challenge After a technical inspection and inventory by Graebener it was clear the pull through plate edge milling machine will be retrofitted and automated The existing 6 000 t pipe forming press will be automated partially and the production line will be supplemented by a 3 000 t pipe forming press In the end the 6 000 t press will be used for the forming of pipes with large wall thickness the 3 000 t press will produce pipes with smaller wall thickness In this context word had already spread that a similar 3 000 t press delivered by Graebener to a pipe manufacturer in Malaysia was one of the fastest and most productive worldwide This press design with its narrow bending sword allows the operator to extract the bending sword completely from the pipe after the bending process In case

  • Gräbener Maschinentechnik: Main focus on Hydroforming
    sector is the ideal supplier of special customized solutions Therefore they deliberately visited the Graebener booth in hall 27 The value added chain i e the full range of products and services in the hydroforming sector was clearly visible for all the visitors even from a great distance from the customer s idea to the simulation engineering and prototyping respectively the small series production up to the customized press tailor made for the operator Torsten Adam This is a very unique feature in the market An important feature In view of the reviving hydroforming sector more and more customers are searching for special customized solutions And this solution is exactly what we can offer them explained Torsten Adam The scope of services comprises feasibility studies forming simulations four hydroforming presses for prototyping purposes and small series production and finally the customized machine concept including a perfectly attuned control and visualization Apart from the considerable demand for hydroforming solutions Gräbener Maschinentechnik also registered various enquiries for other products for example high quality circ and long seam milling machines built by the global market leader plate edge milling machines or other machines for the manufacturing of large LSAW pipes Even customers from

  • Gräbener Maschinentechnik: Hydroforming from A to Z
    Dr Theodor Gräbener Managing Director of the Graebener Group For example in 2002 the RoboClamp the world s most powerful hydroforming press with a closing force of 13 000 t was perfectly and completely tailored to the component to be manufactured a vehicle side rail This engineering approach has always been and still is the philosophy of Gräbener Maschinentechnik In addition to this GMT conducts feasibility studies and forming simulations For the design and engineering of hydroforming presses and the corresponding tools GMT applies most modern software such as CATIA V5 Inventor Mechanical Desktop etc The program FEM Tool Ansys is used for the FEA analysis which is an integral part of the engineering When purchasing the former Schuler premises in Wilnsdorf Schuler Hydroforming the Graebener Group also took over three hydroforming presses With a total of five presses available today GMT can test innovations and in house developments for the sector of Prototyping Small Series Production at short notice using their own machinery Presses with closing forces of 400 2 500 and 10 000 t have been added to the already existing presses with closing forces of 1 500 and 6 500 t Thus Gräbener should be in possession of the world s largest number of prototyping presses says Dr Theodor Gräbener The patented Powerboxx with a closing force of 6 500 t is yet another in house development of GMT for the production of separator plates for fuel cells With the Powerboxx the closing force can be concentrated on a small surface of 300 x 200 mm The 1 500 and 6 500 t presses are already booked solid The 1 500 t press is used continuously by customers for the prototyping and the production of parts in small and medium lot sizes The 6 500 t press
