Thrust air bearing and machining method thereof

The invention discloses a thrust air bearing and a machining method thereof, and relates to the technical field of bearings, the thrust air bearing comprises a bearing body and a pressure equalizing ring, a pressure equalizing groove surrounding the central axis of the bearing body is formed in the working face of the bearing body, and the distance between the inner side groove wall and the outer side groove wall of the pressure equalizing groove is gradually increased in the direction from the groove bottom to the groove opening; a plurality of air outlets are formed in the groove bottom of the pressure equalizing groove at equal intervals, and the outer side wall of the pressure equalizing ring and the outer side groove wall of the pressure equalizing groove are matched to form a flow guide structure inclining outwards. The flow guide structure provides a stable flow path for air and more effectively guides the air in the pressure equalizing groove to flow towards the outer side of the bearing body, so that
