By Flow-Forming the rim section of aluminum wheels, it achieves the improvement of product strength and weight reduction, which is not possible by only turning process.


  • Each roller unit has its individual control axis to allow overlapped process for cycle time reduction.

  • The axial position of each roller can be easily adjusted with NC program.

  • The use of a tool change system allows two or more rollers to be switched over during the process (CW/HW Series).

  • By an optional software, monitoring roller thrust and main spindle motor output are available for cycle time reduction and quality management.
