Research on sealing ring complex curved surface grinding technology

In order to solve the problem of the precision machining of the complex surface of the hydrodynamic seal ring, the precision grinding equipment is used to grind the complex surface. According to the surface structure of the sealing ring, a grinding mathematical model is established, adopting radial ring stacking method and trigonometric formulas to calculate the grinding wheel center movement trace during precision spot grinding. It can provide a strict theoretical basis for the next ultra-precision grinding experiment. According to the movement track, the numerical control program is compiled, and the grinding test of the seal ring is carried out on the self-developed equipment. During the grinding process, the workpiece and the grinding wheel run smoothly. The seal ring test sample meeting the requirements of the face shape is processed, which solves the technical problem of processing the complex face shape. It provides reliable technical support for the subsequent high-precision processing and universal application of the seal ring.
