Mechanical seal rings are core sealing components for pumps, valves, hydraulic equipment and chemical fluid machinery, preventing medium leakage and bearing pressure relying on high-precision plane fitting. Mostly manufactured from high-hardness and wear-resistant materials such as cemented carbide, silicon carbide and ceramics, seal rings require extremely high flatness, parallelism and surface finish. Traditional polishing and conventional grinding processes produce coarse machining textures and large plane errors, leaving microscopic irregularities and tool marks on sealing end faces. This easily causes medium leakage, excessive wear and high-temperature failure during equipment operation, failing to meet the sealing standards of high-pressure, high-speed and corrosion-resistant equipment. The Mechanical Seal Ring Polisher has become the standard equipment for precision finishing of high-end sealing components.
