A9 & A9T Cold Forming Machine
Universal and cost-effective alternativeThe A-Series cold forming machines are used to manufacture high-precision external splines, internal splines and profiles on solid material and sheet-metal components. Depending on the application, various Grob forming processes can be applied.
Machine-specific application
On the A-Series cold forming machines, a wide range of spline geometries and sizes can be produced for numerous applications, such as splines on rotor shafts, fork shafts, clutch carrier plates and more. With the Grob processes used on these machines, even high-strength materials can be formed reliably.
Modular machine configuration
Thanks to the modular system design, the A-Series cold forming machines can be configured precisely to your individual requirements.
Components produced using cold forming stand out through their resource-efficient manufacturing and the broad range of possible geometries, while maintaining high dimensional accuracy and material strength.
The system can be equipped with and combined using various forming technologies. Options include:
- Rolling head: conventional spline profiles
- Radial rolling head: splines up to a shoulder
- Impact punch head: special geometries
- Shifting axis: up to three splines in one clamping operation
- Torque motor: short changeover times with maximum flexibility and performance

FAQ
For which applications are the A9 & A9T Cold Forming Machines suitable?
They are ideal for producing external splines, such as those on rotor shafts, clutch elements, drive shafts or pump components – wherever high precision, strength and repeatability are required.
For which applications are the A9 & A9T suitable?
The produced components are used in drive technology, pump components, gearbox assemblies and electromechanical systems.
How flexible is the A-Series in its configuration?
Thanks to the modular design, the machine can be configured individually and adapted to specific requirements, including the integration of different forming heads.
What distinguishes cold forming with the A-Series?
Cold forming in the A-Series is highly resource-efficient, offers excellent dimensional accuracy and allows a wide range of geometries with consistently high strength.
What is a cold forming machine?
A cold forming machine shapes external splines, internal splines or profiles without heating the workpiece. Forming tools shape the material directly – for example to create drive-spline profiles on shafts.
What is the difference between the A9 and A9T Cold Forming Machine?
The A9 is designed for continuous indexing. The A9T additionally supports interrupted indexing for special spline geometries.
Which dimensions are possible with the A9 and A9T?
The A-Series cold forming machines can produce a wide range of spline geometries and sizes for applications such as rotor shafts, fork shafts or clutch carrier plates. With the Grob forming processes, even high-strength materials can be formed. Please contact us for details and individual guidance.
Which materials can be processed on the A9 & A9T machines?
The A-Series handles solid materials with strengths of up to 1500 N/mm², including various steels, non-ferrous metals and selected cast materials.
Which processes are used on the A9 & A9T?
The machines can be equipped with several Grob cold forming technologies, including: Rolling head for conventional splines, radial rolling head for splines up to a shoulder, impact punch head for special geometries
