Stone edge polishing machines operate by using abrasive elements, such as polishing pads, wheels, or belts, that rotate at high speed against the stone edge. These abrasives gradually remove imperfections, scratches, and roughness, and create a smooth and shiny surface. The machine's design allows for adjusting the angle, pressure, and speed of the abrasives, enabling different edge profiles, from simple chamfers to complex curved edges, depending on the desired finish.
