hei,
kuka osaisi kääntää italiasta suomeen camma di azzeramento (teollisuuskoneisiin liittyvää aineistoa)

t. Leena

Here is the meaning of Camma:
A cam is a rotating or sliding piece in a mechanical linkage used especially in transforming rotary motion into linear motion or vice versa.

Azzeramento means setting back to zero some device.

The only reference I could find about a Camma di Azzeramento on the web is inside a watch mechanism.

Mi Finnish is not even good enough to aswer you on this question, however I hope this explanation can help you somehow. (even if given very late!)
