It is mainly to remove the saw blade traces left by the previous process of stone, and polish the flatness and shape surface of stone in place. The single line map should be roughed, and there should be 0.5mm simo and water grinding allowance when roughed. Semi-fine grinding: remove rough grinding traces, form a new fine line, make the stone surface smooth: fine grinding, fine grinding, clear display of stone surface pattern, particles and color, table main fine and smooth, initial luster, fine grinding, fine grinding stone surface without a trace.
