ABSTRACT:
Finishing a seal assembly as a unit is proposed, which prevents alignment of the end gaps of the annular body and the annular ring of the seal assembly, provides the ability to manufacture the seal assembly to very low tolerances, and establishes virtually perfect parallelism between the upper and lower surfaces of the seal assembly. A finishing process is characterized by lapping a seal assembly as an assembled unit with a lapper using gritted oil as a polishing medium.
