Lapping and polishing is very important to mechanical seal faces/rings.The mechanical seal faces/rings touch the grinding wheels with grinding compounds in a moving way.The high precision can be obtained by the way of removing an extremely thin surface of mechanical seal faces/rings. The lapping and polishing can improve the organizations of seal face surface and reduce friction resistance. Lapping and polishing can make the friction of seal faces smaller and promote surface energy and resistance to corrosion and the polished seal surfaces look nice for the surface reflection co-efficient has improved so they are easy to be checked in optical parallel devices.
