Universal and cost-effective alternative

The 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

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
