Internal forming: Precision from the inside out

With Grob internal forming, we offer you the key to optimal splining

Internal forming

Internal forming

We employ an innovative approach with our Grob internal forming process. Instead of moving the tools around the roller spindles in planetary motion, we generate the splines from the inside out. This results in virtually no gear run-out as we can form very close to a shoulder or shoulders. This alternative enables us to offer you even more precise and versatile solutions.

Advantages

  • Minimal spline run-outs
  • Splining completely formed on the inside
  • Low tooling costs
