Probl\u00e8mes courants dans la coupe des lames de scie \u00e0 granit :<\/p>\n
D\u00e9coupe et combustion : le corps de la lame de scie de la machine \u00e0 scier la pierre est trop dur, le diamant tombe mal ou la hauteur de la lame diamant\u00e9e n'est pas suffisante ;<\/p>\n
\u00c9tincelle de coupe : le ph\u00e9nom\u00e8ne d'\u00e9tincelle est \u00e9galement d\u00fb \u00e0 une mauvaise r\u00e9partition des diamants, ou \u00e0 une matrice trop dure ou trop molle ;<\/p>\n
Chute de coupe : le corps fritt\u00e9 de la lame de scie en granit est l\u00e2che, et la s\u00e9gr\u00e9gation du mat\u00e9riau entra\u00eene la chute de la lame de scie lors du processus de coupe ;<\/p>\n
Saut de lame : une mauvaise r\u00e9partition des diamants dans la lame de scie en granit entra\u00eene un saut de lame, car les diamants ne sont pas r\u00e9partis uniform\u00e9ment dans la matrice, certains endroits sont trop concentr\u00e9s et d'autres sont trop peu nombreux ;<\/p>\n
Coupe non tranchante : pendant le processus de chauffage et de frittage de la lame de scie en granit, les changements de la structure de frittage et des propri\u00e9t\u00e9s m\u00e9caniques sont dus au gradient de temp\u00e9rature entre la pointe et la racine de la dent, \u00e0 l'\u00e9tat d'activit\u00e9 de la poudre et \u00e0 la diff\u00e9rence de distribution du mat\u00e9riau \u00e0 un point de fusion bas.<\/p>\n
En g\u00e9n\u00e9ral, plus la duret\u00e9 du liant est \u00e9lev\u00e9e, plus sa r\u00e9sistance \u00e0 l'usure est importante. Par cons\u00e9quent, lors du sciage de roches abrasives, la duret\u00e9 du liant doit \u00eatre \u00e9lev\u00e9e ; lors du sciage de roches tendres, la duret\u00e9 du liant doit \u00eatre faible ; lors du sciage de roches dures et abrasives, la duret\u00e9 du liant doit \u00eatre mod\u00e9r\u00e9e.<\/p>\n
Lors du sciage d'une lame de scie en granit, la lame de scie sp\u00e9ciale en granit est soumise \u00e0 une force axiale et \u00e0 une force tangentielle. En raison de l'action de la force dans la direction circonf\u00e9rentielle et dans la direction radiale, la lame de scie en granit est ondul\u00e9e dans la direction axiale et en forme de disque dans la direction radiale.<\/p>\n
Ces deux types de d\u00e9formation font que la section rocheuse de la lame de scie n'est pas droite, que les d\u00e9chets de pierre sont plus importants, que le bruit de sciage et les vibrations s'intensifient, que l'agglom\u00e9ration du granit est endommag\u00e9e pr\u00e9cocement et que la dur\u00e9e de vie de la lame de scie est r\u00e9duite.<\/p>","protected":false},"excerpt":{"rendered":"
