Machine \u00e0 couper la pierre<\/a> La lame doit avoir une certaine duret\u00e9, une certaine r\u00e9sistance \u00e0 l'usure et une certaine t\u00e9nacit\u00e9. Il existe g\u00e9n\u00e9ralement quatre mat\u00e9riaux de matrice : le cuivre, le cobalt, le fer et le carbure de tungst\u00e8ne.<\/p>\nParmi eux, le mat\u00e9riau matriciel \u00e0 base de cobalt a le meilleur effet, mais son prix est \u00e9lev\u00e9 et il ne peut pas \u00eatre utilis\u00e9 \u00e0 grande \u00e9chelle. Les mat\u00e9riaux matriciels \u00e0 base de fer sont les plus largement utilis\u00e9s dans la production pratique.<\/p>\n
Afin d'am\u00e9liorer la duret\u00e9 et la r\u00e9sistance \u00e0 l'usure de la matrice, des mat\u00e9riaux \u00e0 point de fusion \u00e9lev\u00e9, tels que le tungst\u00e8ne et le carbure de tungst\u00e8ne, sont souvent ajout\u00e9s \u00e0 la composition, et des m\u00e9taux \u00e0 point de fusion bas, tels que le cobalt, le nickel, le mangan\u00e8se et d'autres alliages \u00e0 base de cuivre, sont utilis\u00e9s comme mat\u00e9riaux de liaison pour le diamant.<\/p>\n
Il existe quatre types de composants ajout\u00e9s dans le mat\u00e9riau de la matrice : le composant squelette, le composant de liaison, le composant d'affinit\u00e9 et le composant de renforcement. Les lames de scie en granit utilisent des mat\u00e9riaux matriciels diff\u00e9rents, dont la composition des additifs est \u00e9galement diff\u00e9rente.<\/p>\n
