This LEIFELD ST Series with 4 rollers is specially designed for very heavy flow forming processes. Due to extremely strong construction of machine frame, and due to enormous forming forces and spindle torque, it is one of the strongest and most powerful flow-forming machines worldwide.
The machine is equipped with four very powerful radial units, which can be off-set axially to each other. This special feature allows highest flexibility and boundless opportunities in flow forming. An axial off-set to zero-line allows fastest forming feedrates. An axial off-set 4 times different allows highest accuracy and perfect surface qualities combined with high reduction rates.
To find the optimum programming for each workpiece a digital, graphical force measuring system is provided to check and evaluate the forming force distribution of all forming axes.
