The invention discloses a high-precision fracturing pump valve seat and a preparation process thereof, and relates to the technical field of valve seat processing. The fracturing pump valve seat is used for solving the technical problems that the assembly precision and the compression resistance of the fracturing pump valve seat need to be improved, and the inner wall of the fracturing pump valve seat cannot be ground and polished with high efficiency and high regulation and control sensitivity during preparation, a compression ring is firstly embedded into a compression ring groove on the periphery of a valve seat body, and then a sealing ring is embedded into a sealing ring groove; the valve seat body and the fracturing pump valve box are tightly assembled; when the valve seat shakes under the action of external force, the pressure-resistant ring plays a role in bearing pressure and relieving stress, and the sealing ring plays a role in sealing and relieving vibration; the compression-resistant ring is in c
