i9 Internal forming machine
Internal forming made easyThe i9 Internal Forming Machine is a universal solution for the precise manufacturing of internal splines or spline-like geometries using the Grob impact punch process. It offers highly versatile application options, short cycle and changeover times, strong process stability and very low tool costs. This makes it suitable for various applications in the automotive, appliance and mechanical engineering sectors where high quality combined with low manufacturing costs is required.
Machine-specific application options
It covers a wide range of applications, for example in automotive, mechanical and appliance engineering. With the i9, splines can be formed in classic lightweight sheet-metal carriers, in ring gears for planetary gearsets, as well as internal drive splines in thick-walled parts. The machine also opens up new opportunities in joining technology, for example for directly joining different components through forming or clinching.
Your advantages
Like all Grob machines, the i9 Internal Forming Machine is based on a refined machine concept focused on efficiency, flexibility and easy maintenance, drawing on decades of experience in building cold-forming machines.
It uses the proven Grob internal impact punch process and can be equipped with up to four different tools.
This allows the forming of parts that were previously difficult or only feasible at high cost, representing a real step forward in designing function-integrated components.
The splines produced in this way offer economic efficiency, high precision and surface quality, combined with the well-known advantages of cold forming: no destruction of the material structure, work hardening, improved material properties, material savings, low distortion during heat treatment, and more.
The advantages of the i9 Internal Forming Machine:
- Universal use
- Up to four different tools
- Forming splines in parts with closed bottom contours
- Joining technology, e.g. direct forming or clinching
- High process stability
- Minimal changeover times
- Easy to maintain, robust and durable
- Available with Fanuc or Siemens control
- Number of spline teeth freely programmable
The i9 Internal Forming Machine brings all known advantages of cold forming: work hardening, material savings, refined structure and excellent surface quality, while reducing components thanks to function-integrated geometries.
