Larger diameters, two metals
Aachener Maschinenbau GmbH (Amba) will be showing two new All-in-One machines at the WIRE 2024 trade show. The BM12 machine is the first screwmaking machine able to produce up to 70 screws per minute from 18-mm-dia wire.

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.

40 High-Strength Bicycle Spokes per Minute
The third generation of Amba’s All-in-One reducing machines further improves the straightness of single- and double-butted spokes – as used in electric and cargo bikes, for example.
80 full-thread screws of up to 420 mm length produced on a single machine in one minute
Aachener Maschinenbau GmbH (Amba) has further enhanced its proven All-in-One machines for long-screw production: The machines are now able to produce up to 420-mm-long full-thread screws of 10 mm outside diameter.
From the wire coil straight to full-thread screws on a single machine
At WIRE 2022, Amba is going to introduce its new all-in-one machine for the production of 10-mm-diameter full-thread screws in lengths of up to 420 mm. It is the first machine in the world able to produce screws of this length and diameter from the coiled wire to the finished product in a continuous cycle.
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.
