The mechanical seal ring and stationary ring grinding

1) Remove the snap ring, after grinding, rough first study, after lapping, conditions can be polished.
2) coarse grinding, the choice of 80 ~ 160 # grit abrasive,wire seal first rubbed machining marks. These can then be abrasive grinding 160 #, so finish to meet the design requirements. Carbide or ceramic ring is required after grinding machine polishing with a polishing. The intensity of polishing machine can be used M28 ~ M5 boron carbide. Polished to a mirror. Ceramic ring available after the M5 agate powder grinding, polishing with chromium oxide.
3) graphite-filled PTFE stationary ring, because the soft material, can be used kerosene, gasoline or water lapping, trailer seals without adding abrasives. In the running-in process can also self-development, so finish requirements are not too high.
4) milling method, and a grinding machine can grind the grinding machine, grinding machine can not on the use of glass-eight manual polishing method.
