DIAMOND SAW BLADE
How to choose a diamond saw blade
Publish Date:2020-11-09
Diamond saw blades are industrial products. Unlike ordinary products, it is not easy to see whether they are good or bad in appearance. In fact, this is also true. Many saw blades have poor quality control, but the quality of the selected segment is better, although it looks ugly, but it is very practical to use. Although the decisive factor of the saw blade is the segment, how to choose the saw blade must be judged through some specific details.In the selection process, we mainly check the following aspects. Through simple visual observation, we can simply make a judgment on the quality of the saw blade.
1. First look at whether the segment on the diamond saw blade is in the same straight line
If the segment is not on the same straight line, it means that the size of the segment is irregular, some may be wide and some narrow, which will cause unstable and affect the quality of the saw blade.
2. Observe whether the weld and the steel blade body are tightly welded
There will be a welding seam and the base body after segment welding on steel blade body. If the arc-shaped surface of the segment is completely fused with the blade body, there will be no gap. The gap indicates that the segment on the diamond saw blade and the blade body are not completely fused. This is because the curved surface at the bottom of the segment is unevenly ground.
3. Measure the weight of the saw blade
The heavier and thicker the diamond saw blade is, the better, because if the saw blade is heavy, the greater the inertial force during cutting, the more stable the cutting performance. Generally speaking, 350mm diamond saw blade should be about 2 kg, 400mm diamond saw blade should be about 3 kg.
4. Check the hardness of the blade body
The higher the hardness of the blade body, the less likely to be deformed. Therefore, whether the blade body hardness reaches the standard directly affects the quality of the saw blade during welding or cutting. It is a good blade for high temperature welding without deformation, and without deformation under force majeure conditions.
5. Test the toughness of the blade body
There are many blade body materials for the saw blade. At present, high-speed steel and alloy steel are the best choices, but the blade body must be tough. Although it cannot be judged directly with the naked eye, it can be considered from the parameters of the saw blade. If the toughness of the blade body is strong, the impact resistance and bending resistance will be better during the cutting process, thereby extending the service life of the substrate.
When selecting a saw blade, you can test the contents of these 5 aspects separately, and compare the above aspects to verify whether the selected saw blade is a high-quality and durable diamond saw blade.

Diamond circular saw blade classification
2020-11-09
Diamond circular saw blades are mainly classified according to size. Generally speaking, they are divided into small-diameter saw blades, medium-diameter saw blades and large saw blades. Small saw blades are also divided according to the shape of the blade, while medium-diameter saw blades can be divided according to the cutting material or the shape of the segment, and the large saw blade is divided according to the purpose. This article introduces the classification of circular saw blades to let you better understand the relevant knowledge of diamond saw blades....
