Abstract: The method of and apparatus for producing fluid dynamic bearing parts is provided. Sets of grooves are formed by an electrochemical machining apparatus based on a design specification. The electrochemical machining process includes a process for extracting one bearing part in every predetermined number of machining cycles during the bearing parts production, a process for measuring shapes of the grooves on the extracted bearing part, a process for comparing the shapes of the grooves on the extracted bearing part with the design specification data, and a process for changing settings of the electrochemical machining apparatus depending on the result of the comparison. With these processes a stable and precise production of grooves on the fluid dynamic bearing parts are possible during mass production.
