Abstract

Inventia se refera la un cutit tubular pentru formarea gaurilor inelare în piesele de prelucrat format dintr-un corp cilindric avand un tronson drept coada de prindere continuat cu un tronson sub forma de cupa cu canale elicoidale de eliminare a aschiilor si cu dinti frontali. Fiecare cutit este prevazut cu o degajare radiala, formata între miezul piesei prelucrate si fata interioara delimitata de o curba, degajarea radiala extinzandu-se circumferinta de la fata posterioara a fiecarei niste interioare formand o margine sau un spatiu îngust pe periferia inferioara a fiecareia dintre ele în directie radiala.
