Flow Forming Machine
Leifeld ST 650 H S Series
The LEIFELD ST 650 H S Series is designed for heavy-duty forming of rotationally symmetrical hollow bodies with constant or varying wall thickness by flow forming via cylindrical, conical or embossed mandrel contours. Close tolerances and highest repeatability can be reached.
The machine is applicable for forming processes like forward flow forming, reverse flow forming and shear forming. A wide range of workpieces can be manufactured on this machine from most different unmachined parts or preforms and materials.
Main Characteristics
- Extremely sturdy and torsion-resistant frame construction
- Axially pulling feed with two diagonally positioned, synchronised ball screws spindle
- Electrically positionable tailstock with ball screw drive
- Loading and unloading can be performed by robots
- Maximum flexibility in the production of lengths, external diameters, wall thicknesses and reduction
