Diamond saw blades are widely used in our daily life, so how to judge the quality of diamond saw blades? Here are some commonly used methods:
1. Observe whether the weld seam and the substrate are welded tightly
Before the weld to the substrate, there will be a weld after brazing. If the curved surface at the bottom of the diamond segment is fully fused with the substrate, there will be no gaps. Gaps indicate that the diamond segments on the blade are not fully fused with the substrate. This is because the circular arc surface at the bottom of the diamond segment is not polished uniformly.
2. measure the weight of the saw blade
The heavier and thicker the saw blade, the better, because the heavier the saw blade, the greater the inertia force during cutting and the smoother the cutting. Generally speaking, the 350mm diamond saw blade should be around 2 kg, and the 400mm diamond saw blade should be around 3 kg.
3. Check from the side whether the diamond segments on the saw blade are on the same straight line
If the diamond segments are not on the same straight line, it means that the size of the diamond segments is irregular, some are wide and some are narrow, which will lead to unstable cutting when cutting stone and affect the quality of the saw blade.
4. Check the substrate hardness
The harder the substrate, the less likely it is to deform. Therefore, whether the hardness of the matrix reaches the standard will directly affect the quality of the saw blade. No deformation during high temperature welding or force majeure. After the base material is processed into a saw blade, it is a good saw blade.
