Disclosed is a high-precision manufacture control method for an electromechanical device. With regard to the design of various parts and components of various electromechanical devices, the present method designs and simultaneously sets various precision technical requirement values of respective concentric geometric tolerances of a plurality of pieces and portions of various structures, provides comprehensive precision adjustable moving fine control parts and components in multi-surface solids of various parts having or not having a rotating or moving part, various orbital motion auxiliary parts, various mechanical components and electromechanical components, respectively provides comprehensive adjustable static fine control parts and components in multi-surface solids of various parts and components of combinations of the above, and provides comprehensive fine control adjustment parts at various positions between the combinations. The parts are manufactured according to technical indices. Assembly is performed and fine adjustment is performed according to comparison calculation fitting of the various designed and set technical requirement values and numerical values measured by various instruments and meters, so that between the above combinations, fixing is performed after various technical requirements of concentric geometric tolerances have respectively been achieved.
