Problems solved by technology

In the existing electrolytic belt grinding, the workpiece is the anode, and the anode dissolves during the electrolysis process. The function of the abrasive belt is only to remove the oxide film formed on the surface of the workpiece by grinding, so as to achieve the effect of grinding. Chips will remain in the interstices between the abrasive grains, reducing grinding efficiency and surface quality
