We were allowed to process a 2-piece welded mill girth gear, module 25, for a well-known plant manufacturer from Austria.

Our task was the complete machinig of the welded semi-finished product provided by the customer.

In order to minimize component distortions during processing as far as possible, all work steps (turning, milling and gear cutting) were carried out once as preliminary and then again as finishing steps.

GearTec AG is currently able to process girth gears with a diameter of up to 4000 mm.

We have once again been able to produce several furnace/mill pinions for a large German plant manufacturer.

This time, at the request of our customer, the pinions were delivered without shafts because they are spare parts.

The pinions in module 28 and module 30, made of 30CrNiMo8+QT, were finish ground to gear quality 5 after gear milling.
