Because of both the power effect and temperature effect, after a long time using, you would notice that there is abrasion on the diamond circular saw blade body. According to different types, such saw blade abrasion can be divided into grinding material abrasion, parts abrasion, binding agent abrasion and so on.

As for the rinding material abrasion, you know, during the whole cutting process, diamond particles would be rubbed with the cutting stone raw materials constantly, then after a while cutting, its seamed edge would become blunt, just like the smooth surface, under such circumstance, diamond saw blade would lost its cutting ability, what’s more, force of friction would be increased at this time and with high cutting temperature, diamond contained in the saw blade would be carbonized, as a result, its hardness would be greatly reduced. In short, this is one vicious circle.

On the diamond particles surface, it will be born the thermal stress because of different and frequent changed cutting power, meanwhile, it will be born the cutting stress, as a result, on the whole saw blade body or some parts, there would be cracking and finally damaged. After a while, you would find the new seamed edge, which is more ideal.
