To solve the problem of stone bending, we must first analyze the two factors causing this problem. The first factor is caused by the diamond saw blade. Most circular saw blades used in circular saw machines are welded from the base to the diamond segment. The quality of the saw blade depends largely on the quality of the substrate, the quality of the diamond tip and the welding quality of the diamond tip. These factors determine the quality of circular saw blades.
1. Saw blade base
Generally, the tension value, flatness and end face jump of the new saw blade base are controlled before leaving the factory. However, some deviations often occur when the base is used in the stone factory, thus affecting the efficiency and qualification rate of stone cutting. decline.
This is mainly reflected in the mismatch between the processing technology used in stone processing plants and the matrix tension value. When the positive value of the tension value is too large, it is easy to cause upward and downward bending. On the contrary, when the negative value is too large, it is easy to cause left and right bending. Some base materials have reached the end of their service life after repeated re-welding. This phenomenon also occurs in human life.
Therefore, we must pay attention during processing. When choosing substrates, don’t be cheap and buy inferior products. The base material should be produced by regular manufacturers. At the same time, attention should also be paid to the service life of the diamond saw blade after re-welding, and the saw blade holder should be replaced in time to reduce unnecessary losses.
2. Diamond segment
The main symptom of diamond segment cutting and bending is that the diamond tip is not sharp enough, cutting or operating under forced overload conditions. The cutting current is too large and the plate is bent. Therefore, we recommend that when using a new diamond tip, cutting measures should be taken before use. It is best to use mechanical cutting, which can reduce the deviation of radial runout and end face runout.
3. Welding of base body and diamond segment
The main manifestation of plate cutting and bending in the diamond segment is that the diamond segment is not sharp enough, and the knife is cut or moved under forced overload. The cutting current is too large and the sheet bends. Therefore, we suggest that when using new diamond segments, cutting measures should be taken before use. It is best to use mechanical cutting, which can reduce the deviation between radial runout and end runout.
