Problems solved by technology

In the prior art, the dedicated grinding wheel for photovoltaic glass includes a grinding wheel base, and a grinding layer is provided on the edge of the grinding wheel base. The grinding layer is usually a diamond layer, and the diamond layer mainly plays the role of grinding during work. The photovoltaic glass with this structure For special grinding wheels, the adhesion between the diamond layer and the grinding wheel substrate is not firm, it is easy to fall off during use, and the cutting ability is poor; in addition, because photovoltaic glass is relatively brittle, it is prone to fragments during processing. Therefore, when processing, not only must be considered Cutting performance, but also to avoid the problem of photovoltaic glass chipping
