It is an abrasive tool used for cutting materials such as metal, stone, and ceramics. Usually made by pressing abrasives (such as alumina, silicon carbide) and binders, it is mounted on equipment like angle grinders and cutting machines, and achieves cutting operations through high-speed rotation. The material and thickness of the cutting wheel vary depending on the materials to be cut (e.g., metal cutting wheels, stone cutting wheels). When in use, it needs to be matched with corresponding equipment and working conditions to ensure cutting efficiency and safety.
