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.The invention relates to a tubular knife for forming the annular holes in the workpieces formed by a cylindrical body having a section as a continuous clamping tail with a cup-shaped section with helical shank removal channels and frontal teeth. Each knife is provided with a radial relief formed between the core of the workpiece and the inner face bounded by a curve, the radial clearance extending the circumference from the posterior face of each inner part forming a border or a narrow space on the lower periphery of each of them in the radial direction.
