Abstract

L'invenzione riguarda un inserto composito per utensili da taglio, costituito da elementi da taglio in materiale ricoperto da rivestimento rafforzante, nel quale il rivestimento rafforzante è formato da uno strato continuo di materiale duro, e gli elementi da taglio sono riuniti in un pacchetto in modo tale che le parti di lavoro vengono ad essere quelle di testata.Figg. 1a e 5.The invention relates to a composite insert for cutting tools, consisting of cutting elements made of material covered with a reinforcing coating, in which the reinforcing coating is formed by a continuous layer of hard material, and the cutting elements are assembled in a package in so that the working parts come to be the head ones. 1a and 5.
