Hollow shafts for gear boxes

Shafts intended mainly for the automatic gear box market.

The technological and economic benefits of the so-called precision cold forging process can be found in the highly competitive near net shape blanks that are obtained thanks to:

  • The substantial savings in materials achieved since the various grooves can be produced directly by forging.
  • The precision of the blank part which allows rationalisation of the finishing stages.

Recommended material grades: the complete range of case-hardened or carbonitrided steels and also steels that enable induction hardening to be used as an alternative to batch treatment.

Methods of production:

  • Forge: using single station and multistation vertical or horizontal presses
  • Finishing: machining, drilling, grinding, batch heat treatment and/or induction treatment, assembly
