FLOW FORMING MACHINE

Leifeld ST 560 H Series

The LEIFELD ST 560 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

  • Near net shape production
  • Highest repeatability of parts production over years
  • Extremely sturdy and torsion-resistant frame construction enables a high level of precision
  • Axially pulling feed with two diagonally positioned, synchronised ball screw spindle
  • Electrically positionable tailstock with ball screw drive
  • Loading and unloading can be performed by robots
  • Maximum flexibility in the production of lengths, diameters and wall thicknesses
