Abstract

In un procedimento ed in un dispositivo, adatto ad esso, la testa (4) dell'attrezzo di taglio rotante con preassegnata velocità angolare, di un dispositivo granulatore in un accostamento di precisione viene avvicinata ad una piastra abrasiva (3), coperta con uno strato di abrasivo, e viene aggiustata mediante molatura cosi da formare una pista di rotazione, geometricamente unitaria, degli attrezzi di taglio (6). Davanti ad un dispositivo con una testa (4) di attrezzo di taglio, supportata fissa sul posto e in comune con la cappa (2) in un tavolo di alloggiamento (1), a tale scopo assialmente longitudinalmente e parallelamente al piano rispetto alla testa (4) dell'attrezzo di taglio, racchiusa concentricamente dalla cappa (2), a modesta distanza è disposta una piastra abrasiva (3) accoppiata con l'estremità frontalmente libera della cappa (2) (Figura 1).
