Vertical automatic spinning machine

The machine is used for the manufacture of complex poly-V-pulleys and damper components. The very short cycle times on this machine are the result of using two turret heads arranged opposite to one another.

The machine can accomodate a wide range of process variation as a result of an optimum programming facility, and the use of up to six forming rollers per turret head. Depending on the workpiece, the following forming programs can be selected:

  • rotary forming from opposing sides using both turret heads simultaneously
  • linear/radial forming using both turret heads simultaneously
  • linear/radial forming using the two turret heads alternately

In addition, it is possible to use the three forming programms in any desired manner for one workpiece programm.


  • vertical layout, modern sturdy, machine design totally enclosed
  • minimum space requirement due to vertical layout
  • frequency controlled AC-motor for main spindle drive
  • two independently controlled CNC-turret heads, each for carrying up to six forming rolls
  • hydraulic ejector in the main and traverse spindle
  • quick tooling and roll changing achieved by optimum accessibility to the machine and the use of a quick changeover system on the turret heads
  • well prepared for automating for use in production lines


  • very short cycle time
  • use of up to twelve forming rollers
  • very low radial and lateral run outs
  • high flexibility and short set-up times by using CNC-control
