C6 Cold Forming Machine
The compact one for fine workThe C6 cold forming machine is the compact solution for the precise production of smaller splines (approx. up to module 2.3) using the Grob cold forming process. It is characterized by very short cycle and setup times, high process stability, and minimal tooling costs, making it ideal for a wide range of applications in the automotive, appliance and mechanical engineering industries, where high quality combined with low production costs is required.
Machine-specific application possibilities
The C6 is particularly suitable for the production of small spline modules and offers a high degree of flexibility and productivity at low acquisition costs. The C6 operates in the continuous partial process and achieves very short machining times. Its main application is in the automotive industry, for the production of torque-transmitting plug-in splines on shafts and axles in the drivetrain, or for the production of high-precision splines, such as for camshafts with shifting cams in engine manufacturing. The C6 is also used in various other applications where low piece costs and high quality are required – such as industrial applications involving pump or shredder shafts.
Your advantages
Like all Grob machines, the C6 cold forming machine impresses with its mature machine concept, focusing on efficiency, flexibility, and maintenance-friendliness, and is based on decades of experience in building cold forming machines.
It is based on and operates with the proven Grob cold forming process, in which the forming is divided into many small steps, which extend across the entire cylindrical section of the forming zone.
The splines produced in this way are characterized by cost-efficiency, highest precision, and surface quality, combined with the well-known advantages of cold forming: no destruction of the material structure, work hardening, improvement of the material structure, material savings, low distortion, etc.
Advantages of the C6 cold forming machine:
- Continuous partial process for shortest machining times
- High process stability
- Minimal setup times
- Maintenance-friendly, robust and durable
- Optional with Fanuc or Siemens control
- Number of workpiece teeth freely programmable

FAQ
Can very long workpieces also be splined with the C6 cold forming machine?
To increase the spline length, the machine can be built with an extended machine bed if required, allowing for the production of almost all commercially available spline lengths.
For which applications is the C6 cold forming machine suitable?
The C6 is mainly used in the automotive, appliance and mechanical engineering industries – for example for the production of plug-in splines on axles and shafts, splines on camshafts with shifting cams, as well as for industrial applications such as pump or shredder shafts.
How flexibly can the C6 cold forming machine be used?
Thanks to the well-thought-out tool holders, the modular machine design, and the freely programmable number of teeth, a wide variety of workpieces can be produced on the C6 with minimal setup effort.
Is the C6 cold forming machine also suitable for series production?
Yes. Due to the very short cycle times, the high process reliability, and the ability to automate the machines according to customer requirements (robot, gantry loader, …), the C6 is ideal for series production of small to very large batch sizes.
What distinguishes the C6 cold forming machine compared to machines from other manufacturers?
The C6 offers very short cycle times, high process stability, and is particularly maintenance-friendly, while having low acquisition costs.
What other advantages does the Grob cold forming process offer?
Work hardening, no destruction of the material structure, very low distortion after subsequent heat treatment, forming of solid material up to a strength of 1,500 N/mm², 1,100 N/mm² for sheet metal.
What spline geometries can be produced with the C6 cold forming machine?
The C6 allows for the production of various spline and spline-like geometries – ranging from classic involute splines to sawtooth geometries.
What spline quality can be achieved with the Grob cold forming process?
According to DIN 5 – 7*, e.g. DIN 5480, 3960 or 3962 * Quality 5 partially.
What surface finish can be achieved with the Grob cold forming process?
Surface roughness of at least Ra 0.4 ~ N5
Which control systems are available?
The machine can be equipped with either Fanuc or Siemens control.
Which process is mainly used on the C6 cold forming machine?
The C6 operates in the continuous partial process using the long-established Grob cold forming process, a chipless forming process for the production of splines and spline-like geometries.
