 Thanks to aLmost 120 years of experience in building screw presses, with continuo us developments, there is practically no drop forging that cannot be manufact ured using a screw press. As far back as 1936. the conventional friction drive was superseded by the friction roller drive and, subsequently, direct drive. In this direct drive, the torque from the drive motor is transmitted to the screw without intermediate drive components, wear parts or energy tosses. This drive concept represents the optimum design solut ion for a screw press drive — in terms of robustness, reliability, maintenance and efficiency.
THE ADVANTAGES
• Wide range of parts
• High repeat accuracy
• High reliability
• High fLexibiLity
• Maximum efficiency
• Frequency Drive

 Sleeper screws are manufactured in three production steps, in Large quantit ies from wire coiLs.These screws have a variety of unique head and thread
designs. During production, the wire section is first cut into sections with a precisely defined Length. In the next production step, part of this cut wire is inductively heated and the screw head is forged in the eccentric press. The third machine rolls the thread, which also involves heating part of the blank using an induction system.
ADVANTAGES
• Wide range of head and thread shapes
• High output
• Flexible production celLs
• Maximum efficiency

 the hydraulic open-die forging press for the forging process. The movements of the press and manipulator are synchron ized by the press contro[.
The forging cell is equipped with a
high-performance, robust direct drive for high stroke rates and reliable operation. If a second manipulator is used as well, there is no need to turn the forgings. This results in much shorter cycLe times. Also. two axles can be forged from one blank, thus further boosting productivity.
ADVANTAGES
• High repeat accuracy
• High reliability
• Automatic forging die change
• Maximum efficiency even with
smaLl batches
• High flexibility
