[0002] Diamond grinding discs, also known as diamond water grinding discs and diamond soft grinding discs, are flexible processing tools made of diamond as abrasive and combined with composite materials. There is nylon hook and loop cloth on the back, which is fastened to the joint of the grinder and used for grinding. It can perform special-shaped processing on materials such as stone, ceramics, glass, and floor tiles. It is suitable for stone polishing, line chamfering, curved plates and special-shaped stone processing.
