Abstract

La présente invention concerne un disque diamanté pour la coupe de produits durs ou abrasifs, tels que les pierres, les granits, les grès, les produits réfractaires, le béton ou produits similaires, disque composé d'un support en tôle (1) dont la périphérie comporte des dents (2) séparées par des encoches (3), ainsi que de segments diamantés (4) de forme précise épousant la courbure de la périphérie du support (1) et dont l'épaisseur est supérieure à celle de la tôle du support. The present invention relates to a diamond disc for cutting hard or abrasive products, such as stones, granites, sandstones, refractory products, concrete or similar products, disc consisting of a support in sheet metal (1) the periphery of which comprises teeth (2) separated by notches (3), as well as diamond segments (4) in the form precise following the curvature of the periphery of the support (1) and whose thickness is greater than that of the sheet of the support.

Ce disque est caractérisé en ce que le bord d'attaque de chaque dent (2) est muni d'un moyen de protec­ tion (5) contre l'abrasion. This disc is characterized in that the edge each tooth (2) has a protective means tion (5) against abrasion.
