Abstract
A unique wavy-tilt-dam shaped mechanical face seal ring, a mechanical face seal which incorporates the wavy-tilt-dam shaped ring, and an apparatus for shaping seal rings. The face shape of the ring is contoured to include a number of waves, tilts and a dam, for the purposes of promoting hydrostatic and hydrodynamic lift, and minimizing leakage in the seal. The apparatus includes a grinding wheel, a drive motor, a spindle, a cam, a cam follower, and flexure mounts to allow slight rotations of the grinding wheel or the face seal ring being ground, and thereby the apparatus machines contours onto the face of the ring.
