Beschreibung

Esecuzione:

Esecuzione per macchine a CN simile a DIN 8093 con codolo cilindrico per il montaggio su mandrini idraulici oppure ad altissima precisione. In questo modo è possibile ottenere la massima precisione di concentricità radiale.
Visualizzazione delle tolleranze:
Dim. 0,6 – 0,9: Tolleranza di produzione o di taglio 0/+0,004 mm.
Dim. 0,98 – 20: Tolleranza di produzione degli alesatori o dei taglienti a norma DIN 1420 per tolleranza del foro H7.
L’acquisto di supporti speciali non è più necessario quando si utilizzano gli alesatori GARANT NC. Con taglienti lunghi ed elica sinistra.

Uso:

Per alesare fori passanti, poiché i trucioli vengono evacuati nella direzione di taglio. Imbocco adatto anche per fori ciechi.

Nota:

Per alesatori come il n. art. 164340 e 164341 con altri diametri e adattamenti vedi n. art. 164344 e 164345.
