Possible to flow form complex shape by single chucking with generating metal flow positively. Spline forming without machining, hub forming without welding are the most typical process. Also it is possible to control the material thickness of the specified portion partially for weight reduction and material saving.


  • Compared with machining, possible to process splines with high speed without chips.

  • Process rollers driven by servo motor and ball-screw allows higher positioning accuracy, which is also effective for low maintenance cost and saving energy.

  • Processing chamber concept which is completely separated from control unit / drive unit makes it possible to prevent troubles and achieve easier maintenance.

  • In order to improve workability and reduce change-over time, mandrel/roller exchange support system is available as an option.
