Diamond saw blade is the most ideal stone cutting tool at present. Today, the ChinShine experts will give you instruction how to distinguish the quality of a diamond saw blade from its appearance.
First of all, look at the diamond segments which are the most important parts of a diamond saw blade. Look over the exposed diamond grits on the surface of diamond segment and observe its concentration and distribution. A good diamond saw blade contains enough and moderate diamond grits which is distributed evenly. Each diamond grit has a “rocket flame”, the longer the flame is, the better the hold of diamond grit, it means that the diamond grit will not drop easily during cutting. Besides, black color diamond grit reveals its poor quality.

Secondly, look at the welding of segments, we could start from the weld seam. The weld seam should be complete and neat, if it is not, and the segment edge is not aligned with the blade slot in vertical, the chip removal and heat radiation will be affected and it may cause segment drop. In addition, you can lift up a diamond saw blade by hand and observe whether the diamond segments are aligned with the blade blank in horizontal, if the segments are uneven and zigzag placed, the stone edges may be damaged during cutting and the diamond segments may drop off.

Thirdly, compare the thickness of diamond segment and blade blank. Take 350mm marble saw blade for example, generally, the thickness of diamond segment is 1mm bigger than the blade blank. And the thickness of 350mm marble diamond segment is 1.0-1.5mm bigger than its blade blank. The purpose of such design is to avoid damage to the blade blank and extend the life of diamond saw blade. In fact, the thickness of diamond segments for saw blade over 1200mm is 2mm bigger than its blade blank. The thickness of diamond segments for saw blade from 800mm to 1200mm is 1.5mm bigger than its blade blank.

In addition, the sharpness and abrasion resistance is in a paradoxical relationship of trade-off. The expert suggests, don’t ask for longer life if the life already meets your demand and the sharpness is moderate. The cutting of diamond saw blade varies according to the situation of saw machine, operation and hardness of stone, once the external environment is changed, the original abrasion-resistant saw blade may be useless.

Finally, in the wake of unfair competition relations, more and more diamond saw blade manufacturers get to use low quality blank to reduce the cost of whole saw blade, it affects the use times of blank directly. Normally, a good quality blank can be recycle-used for 10 times more.

Different saw blade blanks are made of 28CrMo, 30CrMo, 45# steel, 50Mn2V,  65Mn, 75Cr1 or SKS5. 45# steel is used for making low quality saw blade blank (blade core); 28CrMo and 30CrMo is used for making the saw blade for the laser welded diamond saw blade; 50Mn2V and 65Mn are used for making saw blade mainly in China at present; 75Cr1 and SKS5 are better than other raw materials, ChinShine Blade Blanks are made of 75Cr1, 75Cr1 and SKS5 are used for making carbide saw blades as well.

ChinShine experts advice you: not to use a saw blade whose price is abnormal low and pay attention to the importance of blank before purchase.
