The invention discloses a method for preparing a metallographic specimen of spring-like parts. The method comprises the following steps: inlaying the specimen, grinding, polishing and corroding, wherein the specimen is in a cold inlaid manner, and 1200# silicon carbide abrasive paper is adopted in the final accurate grinding process during grinding. The metallographic specimen of spring-like partsprepared by the method disclosed by the invention has high surface quality, a 'backwater' phenomenon is avoided, any microscopic pore does not exist, the parts are tightly combined with the inlay, the working efficiency can be indirectly improved, and the truth of the detection result is improved.
