Diamond circular saw blade is the most ideal stone cutting tool at present, and its appearance has greatly improved the efficiency of stone cutting. At present, the more common specifications of diamond circular saw blades in the market are 185 x 20, 190 x 20, 160 x 20, 165 x 20 and so on.

With the rapid development of the stone market, the demand for circular saw blades is increasing, which has led to the emergence of a large number of saw blade manufacturers in the market. However, many manufacturers do not have mature technology and formula, which makes the production of circular saw blade quality is greatly reduced, which leads to stone merchants waste a lot of time, reduced production, increased expenses, reduced income, etc., so it is particularly important to choose a reliable saw blade manufacturer.

How to choose to identify good quality circular saw blade it

So, how to choose to identify the good quality of circular saw blade? The following three points to answer in detail.

The first by looking at the cutter head exposed diamond, to observe its concentration and distribution status. Good diamond circular saw blade, diamond content is not too little, but also not too much, and uniform distribution.

Second by looking at the welding condition, you can start from two points. First, investigate whether the weld is complete, neat. If the weld is not continuous and the edge of the cutter head is not vertically aligned with the substrate sink, it will affect chip removal and heat dissipation. And it may cause the head to fall off. The second point, the saw blade in the hands, observe the diamond head and the substrate in the horizontal surface is aligned, the head if uneven, vertical and horizontal, it is likely to use over the punch in the plate chipping, and even the head fall off.

Thirdly, compare the thickness of the blade and the thickness of the substrate. To 185mm granite saw blade for example, in general, the head to be thicker than the substrate of about 1mm. 350mm marble saw blade head will be thicker than the substrate of about 0.2mm-0.5mm. The reason for this planning is to avoid damage to the substrate and to improve the service life of the saw blade.

In addition, the sharpness and wear resistance of the saw blade will have a contradictory relationship. Our recommendation is that once the life of the circular saw blade has reached the desired level and the sharpness is moderate, no further increase in life should be required. Because the external environment, such as cutting machine, workers’ operation, stone hardness and other conditions may change at any time, and once the external environment changes, the original wear-resistant saw blade may not be able to use.
