The first forging operation when manufacturing seamless rings is forging ring blanks. Ring rolling lines turn these into the precursors for bearing shells, crown gears, flanges, turbine disks for jet engines and various highly stressed structural elements.
Hydraulic presses are particularly well suited for forging ring blanks: High forces, long strokes and an unlimited rated capacity are the features needed for efficient ring blank forging. Either highly flexible lines or multi-station processes with optimized output are used, depending on the depth of the product range and / or the required output rate. Centering devices, swivel arms, robots and manipulators guarantee suitable parts and die handling.
