How to judge the quality of diamond saw blades

1、 Observe whether the weld seam is tightly welded to the substrate

There will be a weld seam before and after copper welding with the substrate. If the curved surface at the bottom of the blade is completely fused with the substrate, there will be no gap. If there is a gap, it indicates that the blade on the diamond saw blade is not completely fused with the substrate, mainly because the curved surface at the bottom of the blade is not polished evenly.

2、 Measure the weight of the saw blade

The heavier and thicker the diamond saw blade, the better, because the heavier the saw blade, the greater the inertial force during cutting, and the smoother the cutting. Generally speaking, a 350mm diamond saw blade should weigh around 2 kilograms, and a 400mm diamond saw blade should weigh around 3 kilograms.

3、 Side check if the blade on the diamond saw blade is in the same straight line

If the blade is not in the same straight line, it indicates that the size of the blade is irregular, some are wide and some are narrow, which can cause unstable cutting when cutting stone and affect the quality of the saw blade.

4、 Check the hardness of the substrate

The higher the hardness of the substrate, the less likely it is to deform. Therefore, whether the substrate hardness meets the standard during welding or cutting directly affects the quality of the saw blade. High temperature welding does not deform, and under force majeure conditions, it does not deform. It is a good substrate, and after processing into a saw blade, it is a good saw blade.
