Cold-forming replaces multi-step manufacturing processes

Cycle time of one second sets new standard

For the transmission of torques, mechanical engineering solutions rely increasingly on hollow sections because they save significantly on weight compared to solid sections, for example, in automotive applications such as shafts for seat back rests or as drive shafts.

Our new RH 08 synchronous machines form both ends simultaneously. This ensures that during forming both hollow ends stay perfectly aligned with each other.

The hollow sections leave the machine ready to be installed, requiring no additional machining. With a cycle time of approximately one second, the machine achieves an extraordinarily high output.

The first machine of this type - which we recently supplied to a component manufacturer for the automotive industry - is designed with upsetting force of up to 25 t at either end, enabling the machine to process steel and stainless steel hollows with outside diameters of up to 20 mm. The two forming stations arranged in the axial direction of the work piece feature fully automatic, high-precision positioning systems, which allow for hollows in lengths between 450 and 800 mm to be processed on the machine.

AMBA More-in-One

All-in-One becomes More-in-One

Amba has enhanced the functionality of its All-in-One screw and bolt making machines. New machining options provide even higher throughput rates and more flexibility in the screw making shop. The new-generation machines can produce screws with a milled-in notch along their tip at rates of up to 80 pieces per minute.
