The stacked sand abrasive metal abrasive belt adopts a new abrasive technology to aggregate the abrasive particles into a group, and the sand group is evenly bonded to the substrate to form a three-dimensional abrasive structure, which doubles the service life of the product and makes the metal surface to be polished. Uniform and consistent, it is widely used in the field of mechanical polishing of metals, which can improve efficiency, improve quality and reduce costs.
