The invention relates to a high-strength and high-precision cold drawing accurate grinding bar production technology. After a bar produced through a continuous casting and rolling technology is subjected to cold drawing, roundness is greatly improved, meanwhile, the strength of the bar is improved, and the needed mechanical performance is obtained. In addition, a machining hardening layer is formed on the surface, wear resistance of the surface of the bar can be improved, and the accurate grinding bar is obtained after rough grinding and accurate grinding machining, wherein the size precision is h7, the three-point out-of-roundness is smaller than a half of the tolerance, and the surface roughness is smaller than or equal to Ra 0.2 microns.
