For many applications of geared parts it is necessary to have them hardened or heat treated, for example carburized or nitrided or any other treatment. In that case, special techniques and technologies are required for the further machining of the hardened parts. With these technologies for example, occuring geometrical distortions caused by heat treatment may be fully compensated.

Inhouse production is possible up to the following dimensions:

Peel milling:

The hardening of geared parts may cause dimensional deviations of front and superficies surfaces that affect the running smoothness of the meshing parts. Because of that the geared and hardened parts have to be geared a second time. The gear milling tool literally peels of the upper layers of the hardening to reproduce the predetermined dimesions and profile and flank forms. This process may only be performed with the most modern CNC-controlled machinery.

Hard turning:

In additon to the the distortions of the tooth geometry there may also occur dimensional deviations on simple plains. GSC has the inhouse facilities to turn e.g. case-hardened gears on a special purpose lathe. This technology makes it possible to restore an optimal dimensional accuracy. The parts handling on these machines is fully automated.
