  Tolleranze generali di colata per l’ALNICO /General casting tolerance for ALNICO
Rare earth magnetsQueste sono le direttive di tolleranze sulla colata normale che si applicano come regola generale in pollice. La tolleranza piω vicina puς essere ottenuta a seconda delle varie progettazioni, in tal caso sono procedure speciali, si posso fare al momento della colata o tramite operazioni secondarie tipo rettifica, che in tal caso potrebbero aumentare, il costo della colata, o i tempi di produzione.
Tolleranza lineare: per tutte le dimensioni lineari dovrebbe essere utilizzato la tabella di tolleranza qui sotto.
The following are tolerance guidelines on the normal casting and they are applied as a general rule in inch. The closest tolerance can be obtained in accordance with the various planning; in that case they are special procedures, they can be done at the moment of casting or with secondary operations, as grinding, and in that case the cost of casting or the production times could increase.
Linear tolerance: for all the linear dimensions should be used the tolerance chart below:
