Technical Field

[0001] The utility model relates to the technical field of oil seal grinding, in particular to a high-precision stamping oil seal double-sided grinding device. Background Art

[0002] Oil seals are mostly annular rings made of elastic materials. They have super sealing performance in harsh working environments with a lot of coal powder, mud, water vapor, etc. They are a compact mechanical seal, mainly used in low-speed and heavy-load occasions.
