In the process of cutting stone with diamond segments, due to the hardness, abrasiveness, density and other characteristics of natural stone, as well as the diversity of natural stone types, the diamond segments it’s too hard to have the universality in cutting, so it is very common that segments have the problem can’t cut, so what is the specific reason? Let’s take a look:
1: The matrix bond of the diamond segment is too abrasive: the carcass binder of the diamond segment fixes the diamond. When the diamond is cutting the stone, the diamond is constantly consumed, and the matrix will also be constantly consumed. When the consumption is greater than the consumption of the matrix binder, that is, when the abrasiveness of the matrix binder is too high, after the diamond is polished, the diamond segment will not be able to cut the stone, and naturally the diamond segment will not be able to cut the stone.
2: The grade of diamond in the diamond segment is too bad: the grade of diamond is also called the strength of diamond. The higher the strength, the higher the grade. When the diamond grade is relatively poor, the diamond will be consumed very fast when cutting harder stone. If the diamond is consumed, the diamond will be smoothed, then the diamond segment will be can’t cut.
3: The diamond concentration in the diamond segment is insufficient or excessive: the diamond concentration means the diamond content in the diamond segment. If the content is not enough, the diamond segment cannot cut the stone because the diamond is quickly consumed. When the concentration is too high, the diamond will be changed to slow consumption, the cutting edge will be gradually rounded, so that it does not have the cutting ability.
4: The diamond grain size in the diamond segment is too fine: Too small a diamond grain size will greatly reduce the diamond grinding force, and diamonds with small grains are easy to be ground, so usually will choose 50-60 mesh diamonds in stone cutting .
5: The substrate is too soft or bent during the cutting process of the blade: If the substrate of the saw blade is too soft, the segment will be can’t cut, mainly because the blade is bent during the cutting process, which causes the working layer of the blade, It does not participate in cutting or a small part of it participates in cutting. As the deviation of the saw blade increases, the saw blade will break or the surface of the diamond segment participating in the cutting will gradually be smoothed, resulting in the diamond segment being unable to cut the stone.
6: Cutting mechanical problems: When the mechanical power is not enough or the mechanical headstock is damaged, if the hard stone is cut, if the feed speed is too slow, it will directly cause the cutting not to cut or the saw blade to lift the headstock, which will lead to the diamond segment cannot cut the stone.
7: The cutting process encounters the hard layer: This situation occurs from time to time in the process of cutting unknown stone with a saw blade, because the composition of the stone is different, especially when it encounters some metal content or high quartz content. If the hard layer is doped in the stone being cut, it will not be able to cut the stone because the diamond segment is not sharp enough.
8: The sintering temperature and pressure of the diamond segment are not well controlled: mainly because the diamond segment is in the production process, several important parameters are not well controlled, and the sintering process has problems, such as the sintering temperature is too low, the pressure is too low, and the heat preservation time is too low or and pressure maintaining time is too short, the diamond segment will not be able to cut the stone.
9: Insufficient or excessive water supply: This reason is also common. Insufficient water supply will cause the diamond segment to overheat and soften. The softened segment will be directly burned out, and it is inevitable that the stone cannot be cut; Another situation is that the water supply is too large, and the water supply will cause the diamond segment to slip during the cutting process, which causes the diamond segment to not move the stone.
