    L'introduzione delle barre in metallo duro

    1. Le aste in carburo solido di tungsteno sono stampate mediante stampaggio o estrusione.

    2. Le aste in carburo solido di tungsteno sono sinterizzate da un forno integrato di sinterizzazione a bassa pressione, quindi le prestazioni complessive sono elevate.

    3. La barra tonda in carburo di tungsteno-cobalto grezzo, o il diametro esterno della barra tonda, può essere raffinata e lucidata secondo qualsiasi tolleranza. Le tolleranze comuni sono h5, h6, -0,005, ecc., e anche lo smusso finale delle aste in metallo duro può essere lavorato.

    4. Le barre in metallo duro sono adatte per la lavorazione di acciaio generale, ghisa, acciaio inossidabile, acciaio resistente al calore, base di nichel e lega di titanio. Consigliato per materiali per utensili in metallo duro per uso generico come punte elicoidali, frese a candela, maschi e punte a cannone.
