Abstract
A method of manufacturing a dynamic bearing comprises providing a bearing having a through hole. A photoresist is coated on an inner wall of the through hole. An ultraviolet lamp capable of inserting into the through hole is provided. A mask having patterns of pressure-generating grooves is attached to the surface of the ultraviolet lamp. The ultraviolet lamp is inserted into the through hole to perform an exposure process with the mask. The exposed portions of photoresist are developed to appear portions of the inner wall underneath. The appeared portions of the inner wall are etched to form grooves on the bearing, and finally, the photoresist remaining on the inner wall of the through hole is stripped.
