The Technical Service team at SMS group has manufactured a new screw assembly for the screw press that voestalpine Böhler Aerospace (Austria) has been operating since 1982. With this core component, the hydraulically driven screw press HSPRZ1180 with a maximum press force of 315 MN can continue to be employed to meet the demands of the decades to come. The press forges high-load components made of titanium and nickel-based alloys for the aerospace industry.
With a diameter of 1,180 mm, a length of 9,100 mm and a finished weight of 65 t, the spindle has dimensions that only a few manufacturers worldwide are able to produce. The pertaining nut, which itself has impressive dimensions at almost 3,000 mm in length and a finished weight of 36 t, was also manufactured in the SMS group workshop and was paired with the spindle and tested before leaving the workshop.
