Abstract

Lame de scie circulaire, comportant sur son pourtour une succession de dents qui sont conformées alternativement en dents de dégrossissage et de finition et dont les arêtes de coupe sont formées sur des plaquettes ou touches de métal dur fixées par brasage dur dans des alvéoles prévus à cet effet. L'invention prévoit, pour les plaquettes des dents de dégrossissage A et pour celles des dents de finition B, des conformations géométriques à facettes multiples dont les inclinaisons respectives sont déterminées de manière à ce que ces plaquettes soulèvent à chaque passe cinq copeaux de métal, les inclinaisons et angles d'attaque de ces diverses facettes étant déterminés de manière à assurer une répartition uniforme de la pression et donc une moindre usure. Application notamment au tronçonnage des barres d'acier.
