The spur gear consists of two congruent half-rings and of forged, turned and joined components to perform machining operations.

Firstly, the execution cycle included a turning operation followed by gear cutting and drilling.

At the end of the processing cycle, locating keys were applied to the spur gear.

The pictures below show different stages in the manufacture of the spur gear.
