Method of manufacturing rotating device and rotating device

A method of manufacturing a rotating device that includes a base member in which a bearing hole and a tap hole are to be formed, a bearing unit to be inserted in the bearing hole, and a rotating body to be supported by the bearing unit, the method comprising:

• a first machining process of machining the bearing hole while supplying a first cutting lubricant to the base member;
• a second machining process of machining the tap hole while supplying a second cutting lubricant to the base member, the second machining process being continuous from the first machining process;
• a blowing process of blowing at least one of the bearing hole and the tap hole with a fluid in order to eliminate a machining residue;
• a cleaning process of cleaning the base member;
• and
• an assembling process of assembling the base member with the bearing unit and the rotating body;
• wherein the second machining process is executed while a moistening of the first cutting lubricant adhered to the base member after a machining through the first machining process is equal to or higher than a predetermined reference value.
