Cutting and sintering blade: the saw blade body of the stone saw machine is too hard, the diamond falls off improperly or the diamond blade height is not enough;
Cutting and sparking: The sparking phenomenon is also caused by improper distribution of diamonds, or the matrix is too hard or too soft.
Cutting knife jumping: Improper detachment of diamonds in granite saw blades will cause knife jumping, because the diamonds are unevenly distributed in the matrix, some places are too aggregated, and some places are too small;
Cutting off the block: the sintered body of the saw blade is loose, and the material segregation will cause the saw blade to drop off during the cutting process;
The cutting is not sharp: in the heating and sintering process of the granite mining machine saw blade, the change of the sintered structure and mechanical properties caused by the temperature gradient between the tooth tip and the tooth root, the powder activity state and the distribution of the low-melting material; Accumulatively, the mechanical properties of the welded body of the granite saw blade are weakened. The strength of the matrix tissue is weakened by the vibration and impact force transmitted by the diamond, resulting in a reduction in the holding force of the matrix on the diamond.
