Horizontal 3-roller flow-forming machine

The horizontal flow-forming machine HSTR 600/3-6 will meet highest demands concerning flexibility and productivity. Three independently CNC-programmable cross slides permit an economic production of rotationally symmetric workpieces by using the following processes, among others:

  • Flow-forming/flow-turning in forward and reverse flow: production of precision hollow bodies with constant or variable wall thicknesses
  • spinning: production of workpieces or cylindrical preforms starting from round blanks
  • flow-turning/flow-forming operations: production of conical, concave or convex rotationally symmetric hollow bodies starting from blanks or preforms
  • flow-forming of internally toothed workpieces, e.g. clutch and gear parts
  • other profiling and forming operations, e.g. spinning of hubs

Matters of course are the closed framework construction for taking up the forming forces, a particularly solid and exactly supported main spindlefor vibration-free forming as well as a radially movable tailstock as well as an internal ejector and an external stripper.


  • horizontal construction, state-of-the-art and extremely solid machine design with complete enclosure
  • the main spindle is driven by a frequency controlled three-phase current motor with energy recovery
  • automatically actuated three-step gear
  • three flow-turning/flow-forming slides designed as cross slide and offset around the main spindle by 120°
  • one radial and axial CNC-programmable feed axis per cross slide, i.e a total of six CNC-controlled feed axes
  • every axial roller offset is individually programmable or all axial axes can be electronically connected as one axis
  • Tailstock designed as a CNC-axis During reverse flow-turning usable as a length-measuring system (option)
  • two hydraulically actuated stripping cylinders
  • hydraulic ejector in the main spindle
  • fast tool and roller change because of optimal accessibility


  • A very high flexibility in the available forming process because of three independently controllable flowturning/ flow-forming slides
  • any roller offset in axial direction is individually programmable
  • high forming forces in axial and radial direction permit strong degrees of forming even with ample material sizes
  • high rapid feed speeds and persevering power reserves
  • very good access to the working range from front and top
  • high overall effiency


  • Aerospace engineering
  • Military engineering
  • Power and Environmental engineering
